1. PURPOSE 
This analysis report is one of the technical reports containing documentation of the 
Environmental Radiation Model for Yucca Mountain, Nevada (ERMYN), a biosphere model 
supporting the total system performance assessment (TSPA) for the license application (LA) for 
the Yucca Mountain repository. This analysis report describes the development of biosphere 
dose conversion factors (BDCFs) for the volcanic ash exposure scenario, and the development of 
dose factors for calculating inhalation dose during volcanic eruption. 
A graphical representation of the documentation hierarchy for the ERMYN is presented in 
Figure 1-1. This figure shows the interrelationships among the products (i.e., analysis and model 
reports) developed for biosphere modeling and provides an understanding of how this analysis 
report contributes to biosphere modeling. This report is one of two reports that develop 
biosphere BDCFs, which are input parameters for the TSPA model. The Biosphere Model 
Report (BSC 2004 [DIRS 169460]) describes in detail the ERMYN conceptual model and 
mathematical model. The input parameter reports, shown to the right of the Biosphere Model 
Report in Figure 1-1, contain detailed descriptions of the model input parameters, their 
development and the relationship between the parameters and specific features, events and 
processes (FEPs). This report describes biosphere model calculations and their output, the 
BDCFs, for the volcanic ash exposure scenario. This analysis receives direct input from the 
outputs of the Biosphere Model Report (BSC 2004 [DIRS 169460]) and from the five analyses 
that develop parameter values for the biosphere model (BSC 2004 [DIRS 169671]; BSC 2004 
[DIRS 169672]; BSC 2004 [DIRS 169673]; BSC 2004 [DIRS 169458]; and BSC 2004 
[DIRS 169459]). The results of this report are further analyzed in the Biosphere Dose 
Conversion Factor Importance and Sensitivity Analysis (Figure 1-1). 
The objective of this analysis was to develop the BDCFs for the volcanic ash exposure scenario 
and the dose factors for calculating inhalation doses during volcanic eruption (eruption phase of 
the volcanic event). For the volcanic ash exposure scenario, the mode of radionuclide release 
into the biosphere is a volcanic eruption through the repository with the resulting entrainment of 
contaminated waste in the tephra and the subsequent atmospheric transport and dispersion of 
contaminated material in the biosphere. The biosphere process model for this scenario uses the 
surface deposition of contaminated ash as the source of radionuclides in the biosphere. The 
initial atmospheric transport and dispersion of the ash as well as its subsequent redistribution by 
fluvial and aeolian processes are not addressed within the biosphere model. These processes 
influence the value of the source term that is calculated elsewhere and then combined with the 
BDCFs in the TSPA model to calculate expected dose to the receptor. Another objective of this 
analysis was to re-qualify the output of the previous revision (BSC 2003 [DIRS 163958]). 
This analysis is a revision of the Disruptive Event Biosphere Dose Conversion Factor Analysis 
(BSC 2003 [DIRS 163958]). The analysis was performed in accordance with the Technical 
Work Plan for Biosphere Modeling and Expert Support (TWP) (BSC 2004 [DIRS 169573]).

The biosphere model considers FEPs applicable to the Yucca Mountain biosphere 
(DTN: MO0407SEPFEPLA.000 [DIRS 170760]). Consideration of the LA FEP List 
(DTN: MO0407SEPFEPLA.000 [DIRS 170760]) constitutes a deviation from the technical 
work plan (BSC 2004 [DIRS 169573]), which referred to an earlier revision of the FEPs list 
(DTN: MO0307SEPFEPS4.000 [DIRS 164527]). Table 1-1 lists FEPs that are included in the 
biosphere model for the volcanic ash exposure scenario (BSC 2004 [DIRS 169460], Tables 6.2-1 
and 6.3-6). Relationships among the biosphere-related FEPs, the biosphere conceptual model, 
and the exposure scenarios are examined in the Biosphere Model Report (BSC 2004 
[DIRS 169460], Section 6.3); the disposition of the included FEPs within the mathematical 
model, and their explicit relationship to the model equations and input parameters is presented in 
the Biosphere Model Report (BSC 2004 [DIRS 169460], Table 6.7-1). 
The BDCFs developed as output of this report, and used as direct inputs to the TSPA, are the 
results of the biosphere model and are based on the inputs from the supporting parameter reports. 
The BDCFs, therefore, implicitly include the FEPs that are related to the model and to the model 
inputs taken from the supporting parameter reports. Consequently, explicit mapping of 
individual FEPs listed in Table 1-1 to specific sections of this report and BDCFs is not possible. 
All FEPs considered in the biosphere model and its input parameters are collectively included in 
the BDCFs. 
In addition to producing the BDCFs for the volcanic ash exposure scenario, this analysis 
develops the values of inhalation dose factors for calculation of inhalation doses during a 
volcanic eruption. Inhalation dose factors are multipliers, similar to BDCFs, and are used in the 
TSPA to evaluate inhalation dose accrued during a volcanic eruption. The BDCFs do not 
include contributions from inhalation of the falling contaminated ash. They are developed for 
the conditions following ash deposition and are calculated using the ERMYN model in terms of 
annual doses. The ERMYN is not used to calculate inhalation dose factors. The FEPs that are 
related to inhalation dose factors are listed in Table 1-2. The disposition of these FEPs in TSPA 
is through the dose factors that are the input to the TSPA model.

Table 1-2. Features, Events, and Processes Related to Inhalation Dose Factors 
FEP Number a FEP Name a Description of FEP Relationship to Dose Factors 
1.2.04.07.0A Ashfall Volcanic ash is the source of inhalation exposure during volcanic 
eruption. Inhalation dose is proportional to activity concentration in 
the airborne ash (Equation 6.3-2). 
2.4.01.00.0A Human characteristics 
(physiology, metabolism) 
Physiology and metabolism of the human receptor were 
considered in developing the values of breathing rates and dose 
conversion factors for inhalation, which are used as input to 
calculate the values of dose factors (Equation 6.3-3). 
2.4.04.01.0A Human lifestyle Lifestyles and characteristics of people living in Amargosa Valley 
were considered in developing the values of population proportions 
and exposure times, which are used as input to calculate the 
values of dose factors (Equation 6.3-3). 
2.4.07.00.0A Dwellings Dwellings produce mitigating effect on inhalation dose, which is 
considered in the value of the indoor reduction factor for activity 
concentration in air, which is used to calculate the values of dose 
factors (Equation 6.3-3). 
3.1.01.01.0A Radioactive decay and 
ingrowth 
Contribution from long-lived and short-lived decay products of 
primary radionuclides is included in the values of dose factors, 
primarily through the use of effective dose conversion factors for 
inhalation (Table 6.3-1) and also through including long-lived decay 
products in the dose factor for a primary radionuclide. 
3.2.10.00.0A Atmospheric transport of 
contaminants 
Although not directly included in the development of the dose 
factors, atmospheric transport of radionuclides and the process of 
deposition of contaminated ash on the ground are inherently 
included in the calculation of the inhalation dose associated with 
the eruption phase (Section 6.3). 
3.3.04.02.0A Inhalation Dose factors are used in evaluating exposure of the receptor 
arising from inhalation of contaminated resuspended particles 
(Equation 6.3-2). 
3.3.05.01.0A Radiation doses Radiation doses arising from inhalation exposure during volcanic 
eruption will be evaluated in TSPA using dose factors developed in 
this analysis (section 6.3).

2. QUALITY ASSURANCE 
This analysis involved development of data to support performance assessment, as identified in 
the technical work plan (BSC 2004 [DIRS 169573]), and thus, it was a quality affecting activity 
in accordance with AP-2.27Q, Planning for Science Activities. Approved quality assurance 
(QA) procedures identified in the TWP (BSC 2004 [DIRS 169573], Section 4) were used to 
conduct and document the activities described in this report. Specifically, the procedure 
governing development of this document was AP-SIII.9Q, Scientific Analyses. Electronic data 
used in this analysis were controlled in accordance with methods specified in the TWP (BSC 
2004 [DIRS 169573], Section 8). 
The natural barriers and items identified in the Q-List (BSC 2004 [DIRS 168361]) are not 
pertinent to this analysis. A Safety Category per AP-2.22Q, Classification Analyses and 
Maintenance of the Q-List, is not applicable.

3. USE OF SOFTWARE 
This analysis was performed using the verified and validated model, ERMYN, described in the 
Biosphere Model Report (BSC 2004 [DIRS 169460]). The model files were obtained from the 
Model Warehouse (DTN: MO0306MWDBGSMF.001 [DIRS 163816]). The model runs were 
conducted using the GoldSim Graphical Simulation Environment, a graphical, object-oriented 
computer program for carrying out dynamic, probabilistic simulations (GoldSim Technology 
Group 2002 [DIRS 160643]). 
The analysis was conducted using two versions of software qualified under the Office of Civilian 
Radioactive Waste Management, QA program, for use on the Yucca Mountain Project. 
 GoldSim V7.50.100, STN: 10344-7.5.100-00 (BSC 2003 [DIRS 161572]) 
 GoldSim V8.01, Service Pack (SP) 4, STN: 10344-8.01SP4-00 (BSC 2004 
[DIRS 169695]) 
The software was appropriate for the application of running ERMYN model, which was 
implemented using GoldSim software, as described in the Biosphere Model Report (BSC 2004 
[DIRS 169460], Section 6.9). GoldSim was used within the range of validation in accordance 
with procedure LP-SI.11Q-BSC, Software Management. 
Both versions of GoldSim were installed by Software Configuration Management on a DELL 
Precision Workstation 530 computer (CPU# 151554) and run under the Windows 2000 operating 
system. The GoldSim files generated in this analysis are shown in Appendix A. The original 
verification of the model was performed using GoldSim V7.50.100. Verification of the model 
for the use with GoldSim V8.01 SP4 is described in Appendix E. 
In addition, the commercial off-the-shelf product Microsoft Excel 2000 (Version 9.0.3821 
SR-1) was used for data reduction. Standard functions of that software were used to calculate 
values included in tables in Section 6. The use of those functions, including formulas or 
algorithms, inputs, and outputs are described in Appendix B.

4. INPUTS 
4.1 DIRECT INPUTS 
4.1.1 Calculation of Biosphere Dose Conversion Factors 
The inputs to this analysis are listed in Tables 4.1-1 to 4.1-4. Input parameter values and 
distributions were generated specifically for the biosphere model input and are appropriate for 
their intended use. The appropriateness for the intended use in this analysis and uncertainty in 
the input parameters is discussed in detail in the individual analysis reports that document 
parameter development (BSC 2004 [DIRS 169671]; BSC 2004 [DIRS 169672]; BSC 2004 
[DIRS 169673]; BSC 2004 [DIRS 169458]; and BSC 2004 [DIRS 169459]). 
The parameters were used as input for the ERMYN model for the volcanic ash exposure 
scenario, which is included in DTN: MO0306MWDBGSMF.001 [DIRS 163816]. The half-lives 
and branching fractions for radionuclides included in the biosphere model are listed in 
Table 4.1-2. Dose conversion factors for inhalation and ingestion for use in the biosphere model 
are shown in Table 4.1-3. Dose coefficients for exposure to contaminated soil are shown in 
Table 4.1-4. 
The output of Revision 02 of this analysis (DTN: MO0307MWDDEBDC.001 [DIRS 164616]) is 
also a direct input to this analysis. This DTN is re-qualified within this analysis (see 
Appendix C) using a corroborating data approach as a qualification method per AP-SIII.2Q, 
Qualification of Unqualified Data. The Data Qualification Plan is included in Appendix D. 
In the qualification process, DTN: MO0307MWDDEBDC.001 [DIRS 164616] is compared with 
the results of biosphere modeling generated in this analysis to determine the impact of software 
and input changes and to qualify the data. The software change involves the use of GoldSim 
V8.01 SP4 with a corrected Latin Hypercube sampling method. The input differences involve 
small changes in the values of several input parameters between the previous revision of this 
analysis (BSC 2003 [DIRS 163958]) and the current revision. Table 4.1-5 lists the input DTNs 
used by both analyses and summarizes differences between the inputs. 
The direct inputs described in this section were used in Sections 6.2 and in Appendix C to 
calculate BDCFs for the volcanic ash exposure scenario. 
Additional inputs were taken from the textbook references (sources of established fact data) to 
help with the statistical analysis of the results. Specifically, Steel and Torrie (1980 
[DIRS 150857], pp. 278 to 279) was used as a source of statistical tests of hypotheses and Lide 
and Frederikse (1997 [DIRS 103178], p. A-105) was used as a source of percentage points for 
the Student-t distribution.

6. SCIENTIFIC ANALYSIS DISCUSSION 
The objectives of this analysis were to calculate: 
1. The BDCFs for the volcanic ash exposure scenario  these BDCFs are used as input to the 
TSPA model and allow calculating the expected annual dose to the reasonably maximally 
exposed individual (RMEI) from a given concentration of radionuclides in surface soil and 
thickness of volcanic ash deposited on the ground. The dose to the RMEI is used to evaluate 
compliance with the individual protection standard (10 CFR 63.311 [DIRS 156605]). 
2. The dose factors that can be used by TSPA to calculate the expected inhalation dose accrued 
during the period of deposition of volcanic ash on the ground during the volcanic eruption. 
The BDCFs are calculated using the ERMYN biosphere model. BDCFs for the volcanic ash 
exposure scenario apply to the volcanic eruption modeling case of the igneous scenario class. 
The igneous scenario class is one of the TSPA disruptive scenario classes (BSC 2003 
[DIRS 166296], pp. 51 to 52). The disruptive event scenario classes are developed using 
combinations of screened in FEPs that have a low probability of occurrence but may produce 
potentially adverse future conditions. The disruptive event scenario classes include the igneous 
scenario class, which in turn includes the igneous intrusion and volcanic eruption modeling 
cases, and the seismic scenario class, as well as a special case of the stylized analysis of human 
intrusion into the repository. The biosphere model for the volcanic ash exposure scenario, and 
thus the BDCFs generated using this model, support only the volcanic eruption modeling case of 
the disruptive event scenario classes. The remaining disruptive event scenario classes result in 
radionuclide releases to groundwater and are supported by the biosphere model for the 
groundwater scenario. 
6.1 GENERAL CONSIDERATIONS 
6.1.1 Radionuclides Included in the Analysis 
The radionuclides of interest for the biosphere model depend on the exposure scenario, as 
discussed in the Biosphere Model Report (BSC 2004 [DIRS 169460], Section 6.1.3). The 
following 23 radionuclides were identified as important for the TSPA scenario classes involving 
radionuclide release during a volcanic eruption: strontium-90 (90Sr), technetium-99 (99Tc), 
tin-126 (126Sn), cesium-137 (137Cs), lead-210 (210Pb), radium-226 (226Ra), actinium-227 (227Ac), 
thorium-229 (229Th), thorium-230 (230Th), thorium-232 (232Th), protactinium-231 (231Pa), 
uranium-232 (232U), uranium-233 (233U), uranium-234 (234U), uranium-236 (236U), uranium-238 
(238U), neptunium-237 (237Np), plutonium-238 (238Pu), plutonium-239 (239Pu), plutonium-240 
(240Pu), plutonium-242 (242Pu), americium-241 (241Am), and americium-243 (243Am) (BSC 2004 
[DIRS 169460], Section 6.1.3). These radionuclides are referred to in this analysis as the 
primary radionuclides. The list includes radionuclides that are of potential importance during 
both the first 20,000 years and the period of up to 1,000,000 years (BSC 2003 [DIRS 166296], 
Section 1.3). 
The biosphere model accounts for the decay products of the primary radionuclides. The 
short-lived decay products (half-lives less than 180 days) are considered to be in secular 
equilibrium with the parent radionuclide and their contributions to the BDCFs are included in the 

Disruptive Event Biosphere Dose Conversion Factor Analysis 
ANL-MGR-MD-000003 REV 03 6-2 September 2004 
BDCF for the long-lived radionuclide (either a primary radionuclide or its long-lived decay 
product). Two decay products of the primary radionuclides, 228Th and 228Ra, have half-lives 
greater than 180 days and are not automatically included in the BDCFs of the parent when the 
biosphere model is executed. Instead, for biosphere modeling they are treated like primary 
radionuclides. After their BDCFs are calculated, they are added to the BDCF of the parent 
primary radionuclide. In the case of 232Th, its BDCF includes the contribution from 228Ra, 228Th, 
and their short-lived decay products. The BDCF for 232U includes the contribution from 228Th 
and its short-lived decay products. 
6.1.2 Description of the Volcanic Ash Exposure Scenario 
A detailed description of the volcanic ash exposure scenario, including the associated conceptual 
and mathematical models, is presented in the Biosphere Model Report (BSC 2004 
[DIRS 169460], Sections 6.3.2 and 6.5). A brief summary of the main concepts and the 
modeling approach for the volcanic ash exposure scenario is presented in this section. 
The general scenario (the release of radionuclides to the reference biosphere, environmental 
transport, and the subsequent exposure of the receptor) is shown schematically in Figure 6.1-1. 
The immediate source of radionuclides in the biosphere for this scenario is contaminated 
volcanic ash initially deposited on the ground surface following a volcanic eruption. 
After radionuclides enter the biosphere, radionuclide migration through the biosphere occurs due 
to a number of transport processes that lead to contamination and accumulation in the 
environmental media (e.g., soil, air, flora, and fauna). The following environmental transport 
processes are explicitly included in the biosphere model for the volcanic ash exposure scenario: 
 Resuspension of contaminated soil and ash 
 Dry deposition of radionuclides on crop surfaces (resuspension of contaminated soil and 
subsequent adhesion of soil particles on crop surfaces) 
 Translocation of contaminants from the site of deposition to the edible portions of crops 
 Post-deposition contaminant retention by crops (including weathering processes) 
 Radionuclide uptake by crops through the roots 
 Radionuclide uptake by animals through consumption of contaminated feed and soil, 
and subsequent transfer to animal products 
 Exhalation of radon from the soil. 
Human exposure to radionuclides in the environment arises when people come in direct 
(inhalation and ingestion) or indirect (external exposure) contact with contaminated 
environmental media. Table 6.1-1 provides a summary of human exposure pathways included in 
the biosphere model, as well as environmental media and typical activities that may cause 
radiation exposure. Inhalation exposure arising from gaseous emissions from a volcano was not

considered because gaseous radionuclides were not included among radionuclides of interest 
(Section 6.1.1).

6.1.3 Consideration of Climate Change 
Climate refers to the meteorological conditions that characteristically prevail in a particular 
region. The climate model for the Yucca Mountain region was formulated using paleoclimate 
and paleoenvironmental reconstructions based on microfossil records from Owens Lake, 
California cores and calcite isotope records from Devils Hole, Death Valley National Park, 
Nevada. The sequence and duration of past climate periods are identified from the records and 
applied to the Yucca Mountain site, which has a similar climate setting. The temperature and 
precipitation records of present-day meteorological stations at colder and wetter sites are selected 
to represent future climate states (BSC 2004 [DIRS 170002], Section 6.6.1). 
For modeling of climate change in TSPA, the climate shifts in a series of step changes between 
three different climate states in the first 10,000 years: present-day climate, monsoon climate 
(about twice the precipitation of the present day climate), and glacial transition climate (colder 
than monsoon but similar precipitation) (BSC 2003 [DIRS 166296], p. 79). Within the TSPA 
model, these shifts require coordinating the coupled submodels because they must all 
simultaneously change to the appropriate climate state. To support the modeling of climate 
change in TSPA, the BDCFs must also be appropriate for the given climates. The discussion of 
the effect of climate change on volcanic ash exposure scenario BDCFs is presented in 
Section 6.2.5.

6.1.4 Definition of the Receptor 
The regulations for licensing the repository include an individual protection standard for the 
performance of the repository. This standard is expressed as the annual dose limit to a 
hypothetical person called the reasonably maximally exposed individual (RMEI) 
(10 CFR 63.311 [DIRS 156605]). Analysis of annual dose includes potentially pathways of 
radionuclide transport and exposure (10 CFR 63.311 [DIRS 156605]). Changes in the reference 
biosphere, other than climate changes, are not included. 
The RMEI is a hypothetical receptor that meets the following criteria (10 CFR 63.312 
[DIRS 156605]): 
 Lives above the highest concentration of radionuclides in the plume of contamination 
 Has a diet and lifestyle representative of people who now reside in the Amargosa Valley 
based on surveys of the people residing in the Amargosa Valley that determine current 
diets and lifestyles, and then use the mean values of these factors in the assessments 
conducted for 10 CFR 63.311 [DIRS 156605] and 10 CFR 63.321 [DIRS 156605] 
 Uses well water with average concentrations of radionuclides based on an annual water 
demand of 3,000 acre-feet 
 Drinks 2 liters of water per day from wells drilled into the groundwater from a point 
above the highest concentration of radionuclides in the plume of contamination 
 Is an adult who is metabolically and physiologically consistent with present knowledge 
of adults. 
Of the above receptor characteristics those that are related to contaminated water apply only to 
the groundwater exposure scenario and are not used in this analysis. The evaluation of RMEIs 
exposure from contaminated groundwater is provided in the Nominal Performance Biosphere 
Dose Conversion Factor Analysis (see Figure 1-1). 
To satisfy 10 CFR 63.312(b) [DIRS 156605] criteria, the dietary and lifestyle characteristics of 
the RMEI were determined based on surveys of the people living in the town of Amargosa 
Valley combined with national information on behavior patterns. Characteristics of the RMEI 
were developed in a separate analysis (BSC 2004 [DIRS 169671]). 
6.1.5 Biosphere Model 
This analysis was performed using a verified and validated model, ERMYN, which is described 
in the Biosphere Model Report (BSC 2004 [DIRS 169460]). The model files were obtained from 
the Model Warehouse (DTN: MO0306MWDBGSMF.001 [DIRS 163816]). Additional 
verification of the model files for GoldSim V8.01 SP4 is presented in Appendix E. 
The ERMYN model was developed to model the biosphere processes for radionuclides released 
from the geological repository at Yucca Mountain including the environmental transport of 

Disruptive Event Biosphere Dose Conversion Factor Analysis

radionuclides and human exposure. The Biosphere Model Report (BSC 2004 [DIRS 169460]), 
which describes the ERMYN model: 
1. Describes the biosphere model objectives, the reference biosphere, human receptor, 
exposure scenarios, environmental transport pathways and human exposure pathways 
(BSC 2004 [DIRS 169460], Section 6.1) 
2. Develops the biosphere conceptual model based on the site-specific FEPs, the reference 
biosphere and human receptor, and a number of assumptions (BSC 2004 [DIRS 169460], 
Sections 6.2 and 6.3) 
3. Describes the biosphere mathematical model and its submodels based on the developed 
conceptual model and other published biosphere models (BSC 2004 [DIRS 169460], 
Sections 6.4 and 6.5) 
4. Summarizes model input parameters and uncertainty distributions (BSC 2004 
[DIRS 169460], Section 6.6) 
5. Identifies model improvements compared with the previous biosphere model (BSC 2004 
[DIRS 169460], Section 6.7) 
6. Constructs the ERMYN implementation tool based on the biosphere mathematical model 
using GoldSim stochastic simulation software (BSC 2004 [DIRS 169460], Sections 6.8 
and 6.9) 
7. Verifies the ERMYN implementation tool in GoldSim (BSC 2004 [DIRS 169460], 
Section 6.10) 
8. Validates the ERMYN model by comparing the conceptual and mathematical models and 
by comparing the numerical results with results from other published biosphere models 
(BSC 2004 [DIRS 169460], Section 7). 
The ERMYN model was designed to perform an environmental radiation dose assessment and 
can calculate either radionuclide-specific dose or provide a radionuclide-specific BDCF for a 
given receptor. The use of the ERMYN model in the performance assessment is limited to 
calculation of BDCFs. 
Input parameters for the biosphere model are developed and documented in a series of five 
model parameter reports:

submodels, is shown in Figure 6.1-2. The submodels address radionuclide transport to, and 
accumulation in, specific environmental media (e.g., soil, air, plants and animals) and the 
inhalation, ingestion, and external exposure pathways.

6.2 DEVELOPMENT OF BIOSPHERE DOSE CONVERSION FACTORS FOR THE 
VOLCANIC ASH EXPOSURE SCENARIO 
The BDCFs for the volcanic ash exposure scenario were calculated, using probabilistic analysis, 
in a series of simulations for each of the 23 primary radionuclides and two long-lived decay 
products, 228Th and 228Ra (see Section 6.1.1). Each simulation resulted in 1,000 model 
realizations. A model realization is one of the possible model outcomes obtained as a result of a 

Disruptive Event Biosphere Dose Conversion Factor Analysis 
ANL-MGR-MD-000003 REV 03 6-8 September 2004 
single round of sampling of the model input parameters. This section describes the format and 
the summary of the results of biosphere modeling for the volcanic ash exposure scenario, as well 
as their use in the TSPA model. 
6.2.1 Treatment of Uncertainty 
The probabilistic approach was chosen to develop BDCFs. This approach allows statistical 
sampling of parameter values defined by their probability distribution functions. This method, 
called Monte Carlo analysis, provides a quantitative evaluation of the parameter uncertainties 
and their impacts on the modeling outcome. The uncertainty in the model outcome is 
represented by the probability distribution functions of the BDCFs. Input parameter values were 
sampled using Latin Hypercube sampling for consistency with the sampling technique to be used 
in TSPA (BSC 2003 [DIRS 166296], Section 7.3). With Latin Hypercube sampling, the 
probability distribution is divided into intervals of equal probability. The code then randomly 
samples a value within each interval, which results in a more even and consistent sampling 
compared with the conventional Monte Carlo random sampling scheme. The value of the random 
seed was set to 1. 
6.2.2 Format of Biosphere Dose Conversion Factors for Volcanic Ash Exposure Scenario 
and Their Use in the Total System Performance Assessment Model 
The radionuclide concentration in the volcanic ash deposited on the ground surface is the only 
source of radionuclide contamination for the volcanic ash exposure scenario used for 
development of BDCFs in this analysis (direct inhalation of ash during eruption phase is treated 
separately  see Section 6.3). Environmental transport and receptor exposure pathways 
discussed in the previous section depend linearly on this source. 
The integration of the biosphere component into the TSPA model depends on the format of the 
source term, i.e., the activity concentration in the environmental medium that is the source of 
contamination in the biosphere. In the previous assessment, the source was expressed in terms of 
aerial activity concentration (activity of contaminated volcanic ash deposited per unit area of soil 
surface). For the source of radionuclides expressed in such a way, BDCFs for the volcanic ash 
exposure scenario are a function of the thickness of contaminated soil-ash surface layer. 
Because of the anticipated gradual decrease in airborne particulate concentration over time, the 
BDCFs are also a function of time. For the volcanic ash exposure scenario, the BDCFs are given 
in the following format (BSC 2004 [DIRS 169460], Section 6.5.8.2): 
( ) ) ( ) ( ) , ( , , , , , , , a i p inh i v inh i Rn ing ext a i d g BDCF t f BDCF BDCF t d BDCF + + = (Eq. 6.2-1) 
where 
BDCF i(da, t) = BDCF for primary radionuclide i for an ash depth da at time t 
following a volcanic eruption (Sv/yr per Bq/m2) 
BDCFext,ing,Rn,i = BDCF for primary radionuclide i for external exposure, ingestion, 
and inhalation of radon decay products (Sv/yr per Bq/m2) 
BDCFinh,v,i = BDCF for primary radionuclide i for short-term inhalation at

loading (Sv/yr per Bq/m2) 
BDCFinh,p,i = BDCF for primary radionuclide i for long-term inhalation at 
nominal level of mass loading (Sv/yr per Bq/m2) 
f(t) = decay function describing reduction of mass loading with time 
da = thickness of ash (m) 
g(da) = function of ash thickness, da, representing the fraction of total 
activity that is available for resuspension. 
The linearity of this equation is discussed in the Biosphere Model Report (BSC 2004 
[DIRS 169460], Section 6.5.8.2). 
Three BDCF components are calculated for each primary radionuclide. The first component, 
BDCFext,ing,Rn,i, is time independent and accounts for three exposure pathways (exposure to 
sources external to the body, ingestion, and inhalation of radon decay products). The second and 
third BDCF components account for inhaling airborne particulates. Both of these components 
depend on ash thickness. The second term (BDCFinh,v,i) represents short-term inhalation 
exposure during the period of increased concentrations of resuspended particulates following 
volcanic eruption and is time-dependent because mass loading will gradually decrease after an 
eruption. The third term (BDCFinh,p,i) represents long-term inhalation of resuspended particulates 
under nominal conditions (i.e., when the mass loading is not elevated as the result of volcanic 
eruption). The results of the BDCF calculations are in the format of 1,000 row vectors, one for 
each model realization, consisting of three BDCF components for each of the 23 primary 
radionuclides (i.e., 3  23 = 69 BDCF components per vector) and a value of critical thickness, 
as explained below. A vector can be regarded as a one-dimensional array containing the results 
of a single realization of the biosphere model for all primary radionuclides. Technically, the 
model is executed separately for individual primary radionuclides. The vectors are then 
produced by compiling the BDCFs for a given realization number. Such an approach is valid 
because for a given model realization number all radionuclide-independent parameters are the 
same regardless of a radionuclide. 
The function of time, f(t) in Equation 6.2-1, accounts for the reduction of mass loading in the 
years immediately following volcanic eruption. Mass loading decreases exponentially with time 
(modified from BSC 2004 [DIRS 169458], Equation 6.3-1) as 
t e t f . - = ) ( (Eq. 6.2-2) 
where 
. = mass loading decrease constant (1/yr) 
t = time (yr); t = 0 is the first year after a volcanic eruption. 
The mass loading decrease constant (Equation 6.2-2) depends on the ash thickness, and for an 
initial ash depth of less than 10 mm, it is represented by a triangular probability distribution 
function with a mode of 0.33/yr, a minimum of 0.2/yr, and a maximum of 2.0/yr

(DTN: MO0407SPAINEXI.002 [DIRS 170597]). For an initial ash depth of 10 mm or more, the 
mass loading decrease constant is represented by a triangular distribution with a mode of 0.20/yr, 
a minimum of 0.125/yr, and a maximum of 1.0/yr (DTN: MO0407SPAINEXI.002 
[DIRS 170597]).

where dc is the critical thickness of the ash layer. The critical thickness is defined as the 
thickness of the surface soil (ash) layer that is available for resuspension, and the purpose of the 
ash thickness function is to estimate the activity concentration in this layer for the source term 
given as an areal activity concentration of a radionuclide. Since this parameter is represented by 
a distribution, the value of the critical thickness corresponding to the specific BDCF row vector 
must be used. The critical thickness value is thus added to each of the 1,000 BDCF row vectors. 
The calculations of the all-pathway dose for any given primary radionuclide are carried out in the 
TSPA model by combining the source term with the BDCFs. For the volcanic ash exposure 
scenario, the mass loading decrease function and the ash thickness must also be factored in. The 
total annual dose is the sum of the annual doses from individual radionuclides tracked by the 
TSPA (primary radionuclides), including their decay products. The total annual dose, computed 
by the TSPA model, is calculated as

If the radionuclide concentration in the resuspendable layer of surface soil of about 1-3 mm 
thickness (BSC 2004 [DIRS 169672], Section 6.8) is known, the BDCFs developed as described 
above can be used with the following modifications. First, for the two inhalation BDCF 
components, the source term, Csi, having the dimensions of activity per unit area can be 
converted to the mass activity concentration in the resuspendable layer of surface soil by using 
Equation 6.5.1-3 from the Biosphere Model Report (BSC 2004 [DIRS 169460])

Equations shown above use SI units for consistency with the documentation of the ERMYN 
model (BSC 2004 [DIRS 169460]). However, any units can be used to define parameters in 
GoldSim, where the ERMYN model is implemented, as long as they are dimensionally

consistent. In the previous assessments, the output of the BDCF calculations was presented in 
units of rem/yr or mrem/yr per pCi/m2, and this analysis follows the same format. 
6.2.3 Results of the Calculations 
The outcome of the volcanic ash exposure scenario BDCF calculations consists of the three 
BDCF components generated for each radionuclide and each model realization (3 radionuclidedependent 
BDCF components  1,000 realizations per radionuclide  (23 + 2) radionuclides = 
75,000 data points). A summary of these results, in the form of discrete cumulative probability 
distributions of BDCFs in 5 percentile increments, plus means and standard deviations, is 
presented in Tables 6.2-1 to 6.2-3 for the external-ingestion-radon component, short-term 
inhalation component, and the long-term inhalation component, respectively. The list of 
biosphere model files is provided in Appendix A. The means, standard deviations, and 
percentiles were calculated in an Excel spreadsheet VA BDCF Realizations MC_Rev 3.xls, which 
is described in Appendix B. 
In all tables presenting the results of BDCF calculations, BDCFs for 232Th include contributions 
from 228Ra and 228Th; BDCFs for 232U include the contribution from 228Th.

Correlations among input values for the radionuclides have been appropriately established. In 
general, The BDCFs for the volcanic ash scenario can be correlated because most of the input 
parameters, especially those that are radionuclide-independent, are the same for different 
radionuclides. Correlations exist between the BDCF components for a given radionuclide and 
between the BDCFs for individual radionuclides. The rank correlation coefficients for the BDCF 
components are listed in Table 6.2-4. There is no correlation or a very poor correlation between 
the external/ingestion/radon BDCF component and any of the inhalation components because 
these components are related to different exposure pathways and thus depend on a different set 
of input parameters. A stronger correlation exists only between the inhalation BDCF 
components, the long-term and the short-term, because they depend on the same set of 
parameters describing behavior of the receptor and the receptor environments.

The rank correlations between the BDCF components of different radionuclides have also been 
calculated. The correlation coefficients for the external-ingestion-radon component are listed in 
Table 6.2-5. Correlation coefficients for short-term and long-term inhalation components are 
equal to 1. Details of the calculations are presented in Appendix B. Generally, the correlation 
coefficients for the external exposure-radon-ingestion BDCF components are the highest for 
actinides (227Ac and heavier radionuclides) and relatively low for lighter radionuclides. This 
depends on the importance of individual pathways, and input parameters for these pathways, for 
this BDCF component. 
Some correlation coefficients in Tables 6.2-4 and 6.2-5 are shown as equal to zero. This absence 
of correlation between the variables was determined by performing a statistical test on the 
calculated value of the correlation coefficient. The hypothesis was that the (true) population 
correlation coefficient is equal to zero. If the calculated value of the correlation coefficient for 
the sampling distribution is equal to r, one can compute the values of a parameter t, such that

r t (Eq. 6.2-8) 
where n is the number of data points in the sampling distribution, and compare its value with 
Students t for n-2 degrees of freedom (Steel and Torrie 1980 [DIRS 150857], pp. 278 to 279). 
Table 6.2-6 lists the values of t calculated from Equation 6.2-8 for different values of r. The 
hypothesis that the population correlation coefficient is equal to zero (no correlation) can be 
rejected at the 99% confidence level if the value of t is less than 2.576 (Lide and Frederikse 1997 
[DIRS 103178], p. A-105). (The one-tail area under the probability distribution function for 
variable t is equal to 0.995 for t = 2.576.) This corresponds to the value of r equal to 0.0813. 
Note that the distribution of t approaches a normal distribution for the large number of degrees of 
freedom, which is the case here. The correlation coefficient was thus set to zero for the 
calculated values less than 0.0813.

6.2.4 Pathway Analysis 
The exposure pathway contributions to the BDCFs for volcanic ash exposure scenario are 
time-dependent and also depend on the thickness of contaminated ash layer. The pathway 
analysis was first conducted for the initial ash deposition at t = 0 before the mass loading 
decrease occurs, and the ash layer thickness equal to of less than the critical thickness (da = dc). 
For such conditions, the values functions f(t) and g(da) in Equations 6.2-1 to 6.2-3 are equal to 
unity. From Equations 6.2-1 to 6.2-3, when t = 0 and da = dc, then

ANL-MGR-MD-000003 REV 03 6-25 September 2004 
The evolution of BDCFs with time, which is controlled by the function f(t) shown in Equation 
6.2-2, affects only the short-term inhalation component (see BSC 2004 [DIRS 169458], 
Section 6.3, for the development and detailed description of this function). The short-term 
inhalation component accounts for about one-third of the BDCF values presented in Table 6.2-7 
for all actinides. For those radionuclides, the total mean BDCFs show a greater degree of 
reduction over time compared with radionuclides to smaller short-term inhalation components. 
This effect is shown in Figure 6.2-1 for ash thickness equal to 1 cm (10 mm) and the average 
value of the critical thickness (dc = 2 mm). For such conditions, Equation 6.2-1 becomes

(BSC 2004 [DIRS 169458], Section 7.1). The graph was plotted for 90Sr, 226Ra, and 239Pu 
because of the differing pathway contributions for these radionuclides. 
The mean BDCF for 90Sr includes significant contributions from the external, inhalation, and 
ingestion exposure pathways. Ingestion is a relatively insignificant pathway for 226Ra, while the 
mean BDCF for 239Pu is dominated by inhalation.

Figure 6.2-1. Mean Biosphere Dose Conversion Factors as a Function of Time 
The short-term and the long-term inhalation components of BDCFs are affected by the thickness 
of the layer of contaminated ash. When the contaminated ash layer thickness is greater than the 

Disruptive Event Biosphere Dose Conversion Factor Analysis 
ANL-MGR-MD-000003 REV 03 6-26 September 2004 
critical thickness, a fraction of the deposited activity is unavailable for resuspension; only the 
fraction equal to dc/da can become resuspended. That is why the inhalation BDCF components 
are multiplied by dc/da when da>dc. For such conditions, when the ash thickness increases, a 
smaller fraction of the deposited activity would be available for resuspension because an 
increasing fraction would be in ash that is not subject to resuspension (i.e., below the critical 
thickness boundary). Consequently, the inhalation contribution would decrease. This effect, 
which is illustrated in Figure 6.2-2, would be strongest for radionuclides with large BDCF 
contribution from inhalation, such as 239Pu. Figure 6.2-2 shows the BDCFs for the selected 
radionuclides as a function of ash thickness for the point-in-time conditions at t = 0 and for the 
maximum value of the critical thickness (dc = 3 mm). For such conditions, Equation 6.2-1

6.2.5 Climate Change 
Annual doses arising from volcanic eruption are calculated by combining the biosphere 
component (BDCFs) with the source term, i.e., the activity concentration of a given radionuclide 
per unit area (Equation 6.2-4). BDCFs are independent of the source term. The discussion of 
climate change presented here concerns only the biosphere component, the BDCFs, because the 
source term is calculated in the TSPA model. 
A single biosphere model input parameter is affected by climate change: the growing time of 
crops for the human and animal consumption, which potentially may affect the ingestion 
exposure pathway. The ingestion exposure pathway contributes little to the BDCF for most 
radionuclides (Table 6.2-7). The importance of the ingestion pathway gradually increases as the 
short-term inhalation BDCF component decreases, so there is the potential for an increased effect 
of climate change on the BDCFs at later times. 
Because climate change affects only the BDCF component associated with ingestion through the 
growing-time parameter, the value of this component was calculated for a future climate 
represented by the upper bound of the glacial transition climate. The results, in term of the ratios 
of the mean pathway BDCF values for the present-day and future climates, are presented in 
Table 6.2-8. The results of pathway analysis (Table 6.2-8) indicate that the biosphere modeling 
results for the volcanic release of radionuclides are relatively insensitive to the climate change. 
The values in the table are ratios of the pathway BDCFs for the future and present-day climates. 
Since there is no difference between the inhalation, external exposure, and radon pathway 
contributions to BDCF for the present-day and future climates (climate-dependent parameters are 
not used to develop their values) and the difference between the ingestion pathway contributions 
are insignificant, it is recommended that the BDCFs developed for the present-day climate be 
used for the future climates.

6.3 DOSE FACTORS FOR THE ERUPTION PHASE 
The eruption phase of a volcanic event refers to the conditions that exist during the volcanic 
eruption, before the deposition of volcanic ash on the ground is completed. This phase is not 
included in the calculation of BDCFs for volcanic ash exposure scenario because the BDCFs are 
calculated for the conditions that exist after the deposition took place. BDCFs include inhalation 
exposure to resuspended ash and contaminated soil, external exposure, and ingestion exposure 
and are calculated on the annual basis, regardless of the actual eruption time and day. The 
eruption phase is treated separately and its consequences are evaluated as those arising from the 
exposure occurring during an event of a limited duration (acute or near-acute exposure), rather 
than from a long-term, chronic exposure thereafter. The latter is evaluated using the BDCFs. 
The dose factor may be used in TSPA assessments to evaluate whether the doses received by the 
RMEI during an eruption need to be included in calculation of the expected dose. 
Because higher concentrations of airborne radioactive particulates are expected in the air during 
this phase, inhalation of airborne contaminated ash particles is the only pathway considered in 
the analysis for this phase. The other possible pathways, such as external exposure from 
contaminated ash, are inherently included in the BDCFs (Section 6.2). Inhalation exposure 
arising from direct gaseous volcanic emissions was not considered because gaseous 
radionuclides were not included among radionuclides of interest (Section 6.1.1). 
This section describes the development of the inhalation dose factor for the eruption phase 
(Section 6.3.2). To put the eruption phase into perspective, Section 6.3.1 contains a summary of 
mass loading measurements taken during volcanic eruptions. These values are presented for 

Disruptive Event Biosphere Dose Conversion Factor Analysis 
ANL-MGR-MD-000003 REV 03 6-29 September 2004 
reference only but one could compare them with the values of mass loading used as input for the 
biosphere model to calculate volcanic ash scenario BDCFs. 
6.3.1 Mass Loading Levels During Volcanic Eruption 
This section is a summary of airborne particle concentration measurements taken during and 
immediately after volcanic eruptions. This summary is provided to develop an understanding of 
airborne concentrations of ash that may occur at the location of the receptor following a volcanic 
eruption at Yucca Mountain. This information may be used to support evaluation of receptor 
dose during a volcanic eruption, since the biosphere model does not evaluate receptor dose 
during the period of active ash fall. Inhalation dose from airborne particulate concentrations 
during volcanic eruption, if necessary, will be calculated as a component of performance 
assessment. The data presented in this section were not further used in this analysis. 
The data in this section are from four volcanic eruptions at four widely spaced locations. Data at 
each location include measurements made over time and in different local collecting sites. Most 
of the measurements reported in this section were taken at ambient monitoring stations during or 
soon after ash-fall events. Ambient monitoring stations usually are centrally located in 
communities. The concentrations of airborne particles measured at those stations are 
representative of regional or local conditions that are not influenced by specific, immediately 
adjacent activities. 
Mount St. Helens-Total suspended particulate (TSP) concentrations at Yakima, Washington, 
were as high as 35.6 mg/m3 and averaged 13.3 mg/m3 during the first week following the 
May 18, 1980 eruption of Mount St. Helens (Merchant et al. 1982 [DIRS 160102], pp. 912 to 
913). Five to 10 mm of ash were deposited at Yakima during that eruption (Sarna-Wojcicki et 
al. 1982 [DIRS 160227], Figure 336). 
The peak, short-term (about 4-hour) TSP concentration measured in Missoula, Montana, on 
May 19 (the day of greatest ash fall at that location) was 19.9 mg/m3. The average daily 
concentrations there decreased from 11.1 mg/m3 on May 19 to 0.9 mg/m3 on May 22 
(Johnson et al. 1982 [DIRS 164149], pp. 1067 to 1068). About 2.5 to 5 mm of ash was 
deposited at Missoula (Sarna-Wojcicki et al. 1982 [DIRS 160227], Figure 336). 
The daily average TSP concentration in Clarkston, Washington, on May 18 was 0.68 mg/m3. 
About 0.5 mm of ash was deposited there from that days eruption. At Longview, Washington, 
the average daily concentration on May 27 was 1.42 mg/m3. About 1 to 2 mm of ash was 
deposited on that city during an eruption on May 25 (DTN: MO0008SPATSP00.013 
[DIRS 151750], EPA monitoring sites 53-003-0003 and 53-015-0008; Sarna-Wojcicki et al. 
1982 [DIRS 160227], Figures 336 and 344). 
About 10 percent or less of the ash from Mount St. Helens was =10 m (PM10) (Craighead et al. 
1983 [DIRS 160338], p. 6; Buist et al. 1986[DIRS 144632], p. 40). PM10 is defined as 
particulate matter with mass median aerodynamic diameter less than 10 m. 
Soufriere Hills-Peak PM10 concentrations at 3 locations during an eruption of the Soufriere 
Hills volcano (Montserrat, British West Indies) in 1997 were about 0.3 to 1.0 mg/m3 outside a 

Disruptive Event Biosphere Dose Conversion Factor Analysis 
ANL-MGR-MD-000003 REV 03 6-30 September 2004 
school, 0.1 mg/m3 inside that school, and 0.4 to 1.5 mg/m3 outside a hotel (Baxter et al. 1999 
[DIRS 150713], Figure 3 and p. 1142). The fine ashfall deposits from this volcano typically 
contained 60 to 70 percent (by weight) of 10 to 125 m particles and 13 to 20 percent of particles 
<10 m. Using a ratio of PM10 to TSP concentrations of 1:5 (calculated based on the average 
fraction of particles <10 m in the deposited ash), peak TSP concentrations were about 1.5 to 
5.0 mg/m3, 0.5 mg/m3, and 2.0 to 7.5 mg/m3, respectively at the three locations. These 
concentrations likely did not include resuspended particles as they were taken late in the day 
after activities at the sites had ceased. 
Searl et al. (2002 [DIRS 160104], Table 11) estimated mean personal PM10 exposure 
concentrations for various activity levels during and after eruptions of the Soufriere Hills 
volcano. Using a PM10 to TSP ratio of 1:5, estimated TSP concentrations during periods with 
alert levels to very high levels of ash were 1.5 to 5 mg/m3 for people inactive indoors, 2.5 to 
10 mg/m3 for active indoors, 5 to 15 mg/m3 for active outside, and 25 to 50 mg/m3 for dusty 
occupations. These estimates include the influence of particle resuspension during activities. 
Mt. Spurr-The maximum hourly PM10 concentration in Anchorage Alaska, during the 1992 
eruption of Mt. Spurr was 3 mg/m3. The 24-hour average concentrations the day after the 
eruption was 0.565 mg/m3. About 8 to 15 percent (by weight) of ash particles from that eruption 
collected near Anchorage were <15 m, and 5 to 10 percent were between 2.5 and 10 m, 
resulting in an approximate PM10 to TSP ratio of 1:10. Based on this ratio, the peak TSP 
concentration in Anchorage was about 30 mg/m3 and the 24-hour average was about 5.7 mg/m3 
(Gordian et al. 1996 [DIRS 160111], p. 290; McGimsey et al. 2001 [DIRS 160386], 
Figures 11 and 12). 
Mt. Sakurijima-Yano et al. (1990 [DIRS 160112], p. 373) stated that peak, 2-minute 
concentrations higher than 2 mg/m3 have been measured in high-exposure areas after eruptions 
of Mount Sakurijima (Japan), and that these high levels of suspended particulate matter seldom 
last long, and they usually decrease rapidly to approximately 0.1 mg/m3. 
In summary, daily average concentrations of ash outdoors during an eruption may be as low or 
lower than 1 mg/m3 for light ashfall events or as high or higher than 15 mg/m3 for high ashfall 
events. Concentrations indoors would be much lower (see also BSC 2004 [DIRS 169458], 
Section 6.2). It should be noted that high ambient concentrations reported here do not result in 
an under-representation of the risk estimate because they likely are overestimates of 
concentrations inhaled because it is well documented that during volcanic eruptions people take 
actions, such as staying indoors and wearing masks, to reduce the amount of ash they inhale 
(Johnson et al. 1982 [DIRS 164149]; Buist et al. 1986 [DIRS 144632]; Nania et al. 1994 
[DIRS 164156]). 
6.3.2 Development of Dose Factors 
As noted before, dose factors are developed to account for the inhalation exposure during an 
eruption phase. The dose factors are developed separately from BDCFs because BDCFs are 
developed for annual exposures and do not address relatively short-term exposure conditions 
during a volcanic eruption. The biosphere model described in the Biosphere Model Report 
(BSC 2004 [DIRS 169460]) is not used to calculate the dose factors. 

Disruptive Event Biosphere Dose Conversion Factor Analysis 
ANL-MGR-MD-000003 REV 03 6-31 September 2004 
The dose factor for a given primary radionuclide is numerically equal to the dose resulting from 
a one-day intake of this radionuclide (and associated short-lived decay products, if present) by 
inhaling air containing a unit activity concentration of the radionuclide under consideration (e.g., 
1 Bq/m3) and its short-lived decay products. For a unit activity concentration of a radionuclide 
in air, radionuclide intake depends on inhalation exposure time and breathing rate. 
In the biosphere model, the dose to the RMEI from inhalation exposure to a given primary 
radionuclide i and its short-lived decay products present in airborne particulates is calculated 
(modified from annual dose to daily dose from BSC 2004 [DIRS 169460], Section 6.4.8.1) as

n = environment index; n = 1 for active outdoors, 2 for inactive outdoors, 3 for

BRn = breathing rate for environment n (m3/hr) 
m = population group index; m = 1 for local outdoor workers, 2 for local 
indoor workers, 3 for commuters, and 4 for non-workers 
PPm = fraction of total population in population group m 
t n, m = number of hours per day a population group m spends in environment n 
(hr/d). 
For calculating the inhalation dose, the exposure times for different population groups and 
environments, as well as the associated breathing rates, were developed (see Section 4.1 for a list 
of model input parameters). For the duration of volcanic eruption, environment-specific 
breathing rates and the fractions of time spent indoors versus outdoors are considered relatively 
unchanged compared to the pre-eruption conditions. Therefore, the same parameter values for 
lifestyle characteristics as those used for the BDCF calculation were used to develop dose factors 
for the eruption phase. 
Because a volcanic eruption is an unusual event, it is possible that people would not behave as 
they would under normal circumstances. However, it is difficult to predict how the human 
behavior would change. Some people may seek shelter from falling ash and spend more time 
indoors where exposure would be reduced, while other people may, for instance, perform ash 
removal from their property and spend more time outdoors. 
Ash depths 18 km downwind from Yucca Mountain were predicted to range from 0.07 to 55 cm 
(based on 100 realizations of the ASHPLUME model). About 35 percent of predicted depths 
were less than 1 cm, 75 percent were less than 5 cm, and 90 percent were less than 15 cm 

Disruptive Event Biosphere Dose Conversion Factor Analysis 
ANL-MGR-MD-000003 REV 03 6-32 September 2004 
(BSC 2004 [DIRS 170026], Table 6-4). Ash depths at the location of the RMEI (18 km south of 
Yucca Mountain) would be about 2 orders of magnitude or more lower under normal, variable 
wind conditions (CRWMS M&O 2000 [DIRS 153246], Section 3.10.5.1 and Figure 3.10-14) 
because the wind at Yucca Mountain blows to the south infrequently (BSC 2004 [DIRS 170026], 
Figure 8-1). 
For the small amount of ashfall and an eruption lasting for several days, it is likely that the 
airborne particulate concentrations would not be substantially different from the pre-eruption 
levels. If this is the case, people would not modify their behavior to the extent that their overall 
average daily breathing rate would be affected, in which case the assumption is realistic. If 
airborne particulate concentrations were much greater than the pre-eruption levels, people would 
take actions to reduce the amount of ash they inhale, such as staying indoors and wearing masks 
(Section 6.3.1), and this assumption would lead to conservative results. In summary, using the 
same lifestyle characteristics parameter values for the eruption phase dose factors as those used 
for the volcanic ash exposure scenario BDCF calculations is considered technically defensible 
and not to result in an under-representation of the risk estimate. 
It is further postulated that during volcanic eruption, the average level of mass loading indoors 
arising from the original deposition of tephra is one-half of that outdoors, or equivalently, the 
indoor reduction factor for activity concentration in air is equal to 0.5. This value does not 
concern activity concentrations resuspended due to atmospheric or mechanical processes 
following the initial deposition. 
This indoor reduction factor is based on the ratio of the post-volcanic mass loading values indoor 
and outdoor in the absence of soil disturbing activities causing resuspension of deposited ash. 
Undisturbed conditions were chosen because the process of resuspension and the resulting 
inhalation of resuspended particulates are included in the BDCFs. 
The ERMYN divides the biosphere into the five environments (BSC 2004 [DIRS 169671], 
Section 6.2). These mutually exclusive environments represent the behavioral and 
environmental combinations for which a person may receive a substantially different rate of 
exposure via inhalation or external exposure. These environments are: 
Away from Potentially Contaminated Area environment accounts for time spent away from 
areas contaminated by groundwater or volcanic ash, including time spent working and 
commuting to work by those that work outside of contaminated areas. 
Active Outdoors environment, which accounts for time spent active outdoors, includes time 
spent outdoors in contaminated areas conducting activities that resuspend soil. 
Inactive Outdoors environment represents time spent commuting within contaminated areas and 
time spent outdoors in the contaminated areas conducting activities that do not resuspend soil. 
Asleep Indoors includes time spent sleeping indoors within contaminated areas. 
Active Indoors includes time spent awake, indoors within contaminated areas, including work 
time. It is calculated in the model as the remainder of the day not spent in the other 
environments. 

Disruptive Event Biosphere Dose Conversion Factor Analysis 
ANL-MGR-MD-000003 REV 03 6-33 September 2004 
Two environments that are not associated with soil disturbing activities are the inactive outdoor 
and asleep indoor environments. The modes of the mass loading distributions are 0.060 mg/m3 
and 0.030 mg/m3 for the inactive outdoor and asleep indoor environments, respectively 
(DTN: MO0407SPAINEXI.002 [DIRS 170597]), indicating that dwellings provide about 
50 percent reduction of the outdoor mass loading level. 
Thus, assuming that the radionuclide concentration in the indoor air is a fraction of that in the 
outdoor air, Equation 6.3-1 can be modified as

where

has not yet fallen on the ground (Bq/m3) 
IRFn = indoor reduction factor for activity concentration in air (dimensionless) 
DFi = dose factor for a primary radionuclide i (Sv/d per Bq/m3). 
The activity concentration of a radionuclide i in outdoor air for the ash that has not yet fallen on 
the ground, Cai,outdoor, does not depend on the outdoor environment, as defined for the biosphere 
model (i.e., active outdoor and inactive outdoor), because this quantity is independent of human 
activities. The indoor reduction factor is equal to 1 for the outdoor environments (active 
outdoors and inactive outdoors) and to 0.5 for the indoor environments (asleep indoors and 
active indoors). The term in the brackets in Equation 6.3-2 is the effective daily breathing rate, 
i.e., the volume of outdoor air that contains the same amount of contaminant (radionuclide) as 
the air that is breathed in by a person in one day.

The effective dose conversion factors for inhalation include, where applicable, contributions 
from the associated short-lived decay products. They were developed by calculating a sum of 
the dose conversion factors for inhalation, weighted by the associated branching fractions, as 
shown in Table 6.3-1. Dose conversion factors used in this analysis 
(DTN: MO0407SPACRBSM.002 [DIRS 170677]) are from Federal Guidance Report No. 11 
(Eckerman et al. 1988 [DIRS 101069]). These DCFs were developed for radiation protection in 
the workplace and are usually applied to chronic low-dose, low-dose rate exposures. However, 
the same values are also recommended for conducting radiological assessments for consequence

analysis in the case of accidental releases (Sjoreen et al. 2001 [DIRS 164093], Section 4.9.1), 
where calculated doses can exceed 250 rem (Sjoreen et al. 2001 [DIRS 164093], Table 7.1). 
The dose factors are calculated as deterministic quantities using the mean values of parameters. 
They are provided to allow estimating the dose during the eruption phase. In the previous 
performance assessment, the dose calculated for the eruptive phase did not significantly 
contribute to the calculated expected annual dose, which was shown in the sensitivity analyses 
for the TSPA for the Site Recommendation (CRWMS M&O 2000 [DIRS 153246], 
Sections 3.10.3.1 and 5.2.9.9). Calculations of the individual terms in Equation 6.3-3 are shown 
in Table 6.3-2.

This section summarizes the derivation of volcanic ash exposure scenario BDCF values and 
recommendations for their use in the TSPA model, as well as the derivation of inhalation dose 
factor values for the eruption phase of the volcanic event. The output of this analysis is included 
in several data sets, as shown in Table 7-1.

The output of this analysis includes the new data (DTNs MO0407MWDBMVAE.000, 
MO0407SPADFIDV.000, and MO0407MWDGSMFV.000) as well as the re-qualified results 
(DTN: MO0307MWDDEBDC.001) from Revision 02 of the analysis (BSC 2003 [DIRS 
163958]). The output of the previous analysis included in one DTN two data sets: BDCFs for 
the volcanic ash exposure scenario and the inhalation dose factors for the eruptive phase. The 
BDCFs from that data set are compared to the new BDCFs developed in this analysis 
(DTN: MO0407MWDBMVAE.000) in Appendix C. 
The results of the impact analysis presented in Appendix C (see Section C.3 for conclusions) 
indicate that the differences between the BDCFs included in DTN: MO0307MWDDEBDC.001 
and those in DTN: MO0407MWDBMVAE.000 are negligible and either DTN can be used in 
the TSPA model as a source of BDCFs. The impact was evaluated by comparing the mean, 5th 
percentile and 95th percentile values for the BDCF components. For both inhalation 
components, the differences between the values of these statistics do not exceed 10 percent. For 
the ingestion/external/radon component, the difference exceeds 10 percent in only one case: the 
95th percentile value for 237Np, and it is about 23 percent. However, for this radionuclide 
ingestion and external exposure pathways are negligible contributors for the all-pathway dose 
(radon pathway is not applicable for this radionuclide). It can thus be concluded that both BDCF 
sets can be used interchangeably. 
The DTN: MO0307MWDDEBDC.001 includes dose factors for evaluating daily inhalation 
doses during a volcanic eruption. The inhalation dose factors in the 
DTN: MO0407SPADFIDV.000, which is an output of this analysis, are the same except for the 

Disruptive Event Biosphere Dose Conversion Factor Analysis 
ANL-MGR-MD-000003 REV 03 7-2 September 2004 
values for 90Sr, which differ by about 0.3 percent due to rounding. This difference is negligible 
and both sets can be used interchangeably. 
The values of the BDCFs were developed using the ERMYN biosphere model and remain valid 
within the application and validation limits of the model (BSC 2004 [DIRS 169460], 
Section 8.2). Specifically, the BDCFs were developed for a specific assessment context, 
described in the Biosphere Model Report (BSC 2004 [DIRS 169460]), the reference biosphere, 
and the receptor. If used for other situations, the BDCFs may not apply. 
For the contaminated volcanic ash exposure scenario, the model applies to a layer of small ash 
particles that could be resuspended into the air. The model and the BDCFs do not apply to other 
volcanic media, such as contaminated gas, lava, or coarse ash. Some assumptions regarding the 
model development (BSC 2004 [DIRS 169460], Section 6.3.2.4) are based on thin ash deposits; 
if thick ash deposits occur, the model might overestimate the BDCF values. For example, the 
external exposure is assumed in the biosphere model to originate from a contaminated ground 
surface. If the deposit were thick, the external exposure would be reduced because of 
self-absorption of the fraction of radiation emitted from contaminated ash/soil. The biosphere 
model assumes that the entire deposited activity is mixed into the surface soil and available to 
plants. For the deposits thicker than the rooting depth of plants, a portion of the deposited 
activity would not be available for plant uptake. 
The ERMYN model does not apply during a volcanic eruption when volcanic ash is still in the 
air (i.e., before initial settling on the ground). For the eruption period, the inhalation dose factors 
should be used. 
7.1 ANALYSIS SUMMARY 
7.1.1 Incorporation of Uncertainty 
The outputs of the biosphere model are BDCFs for volcanic ash exposure scenario. To 
incorporate uncertainty in the model input, BDCFs were calculated in a series of 1,000 model 
realizations. The resulting probability distribution represents uncertainty in the BDCFs. The full 
set of BDCFs consists of the three BDCF components generated for each of 23 primary 
radionuclides and each model realization. The summary of these results, in the form of discrete 
cumulative probability distributions of BDCFs in 5 percentile increments, plus means and 
standard deviations, is presented in Tables 6.2-1 to 6.2-3 for the external exposure-ingestionradon 
component, short-term inhalation component, and the long-term inhalation component, 
respectively. The full set of BDCF vectors for each realization is included on a CD-ROM 
(Appendix B) in the file VA BDCF Realizations MC_Rev 3.xls. 
Consideration of uncertainty was not included in the calculation of the dose factors because these 
parameters were developed as a scoping tool for the TSPA, as explained in Section 6.3.2. 
7.1.2 Format of the Biosphere Dose Conversion Factor Input to TSPA 
Three BDCF components are calculated for each primary radionuclide (Section 6.2.2). The first 
component, BDCFi, is time independent and accounts for three exposure pathways (ingestion, 
inhalation of radon decay products, and external exposure). The second and third BDCF 

Disruptive Event Biosphere Dose Conversion Factor Analysis 
ANL-MGR-MD-000003 REV 03 7-3 September 2004 
components account for inhaling airborne particulates. Both of these components depend on ash 
thickness. The second term (BDCFinh,v,i) represents short-term inhalation exposure during 
increased concentrations of airborne particulates following volcanic eruption and is timedependent 
because mass loading will gradually decrease after an eruption. The third term 
(BDCFinh,p,i) represents long-term inhalation of suspended particulates under nominal conditions 
(i.e., when the mass loading is not elevated as the result of volcanic eruption). The results of the 
BDCF calculations are in the format of 1,000 row vectors, one for each model realization, 
consisting of three BDCF components for each of the 23 primary radionuclides (i.e., 69 BDCF 
components per vector) and a value of critical thickness of ash corresponding to the specific 
BDCF vector. A vector can be regarded as a one-dimensional array containing the results of a 
single realization of the biosphere model for the primary radionuclides. 
Some BDCFs include contributions from their decay products. The primary radionuclides 
(radionuclides tracked in the TSPA) and the decay products, which were included in the BDCF 
with the primary radionuclides, are shown in Table 7.1-1.

7.1.3 Use of Biosphere Dose Conversion Factors for Volcanic Ash Exposure Scenario 
Calculating the annual all-pathway dose for any given primary radionuclide is done by 
combining the source term with the BDCFs. In the case of the volcanic ash exposure scenario, 
the mass-loading decrease function and the ash thickness also are factored into the calculations. 
The total annual dose is the sum of the annual doses from individual radionuclides tracked in the 
TSPA (primary radionuclides), including their decay products. The total annual dose, computed 
by the TSPA model, is calculated as

(Eq. 7.1-1) 
where 
Dtotal(da,t) = time- and ash thickness-dependent total annual dose to a defined 
receptor resulting from the volcanic release of radionuclides from the 
repository (Sv/yr) 
Csi(t) = time dependent activity concentration of radionuclide i in volcanic ash 
deposited on the ground (Bq/m2) 
BDCF i(da,t) = BDCF for primary radionuclide i for an ash depth da at time t 
following a volcanic eruption (Sv/yr per Bq/m2) 
BDCFext,ing,Rn,i = BDCF for primary radionuclide i for external exposure, ingestion, and 
inhalation of radon decay products (Sv/yr per Bq/m2) 
BDCFinh,v,i = BDCF for primary radionuclide i for short-term inhalation at 
post-volcanic level of mass loading in excess of nominal mass loading 
(Sv/yr per Bq/m2) 
BDCFinh,p,i = BDCF for primary radionuclide i for long-term inhalation at nominal 
level of mass loading (Sv/yr per Bq/m2). 
The time function, f(t), accounts for the reduction of mass loading in the years immediately 
following volcanic eruption. The mass loading is assumed to decrease exponentially with time 
as 
t e t f . - = ) ( (Eq. 7.1-2) 
where 
. = mass loading decrease constant (1/yr) 
t = time (years); t = 0 is the first year after a volcanic eruption. 

Disruptive Event Biosphere Dose Conversion Factor Analysis 
ANL-MGR-MD-000003 REV 03 7-5 September 2004 
The mass loading decrease constant (Equation 7.1-2) depends on the ash thickness, and for an 
initial ash depth of less than 10 mm, it is represented by a triangular probability distribution 
function with a mode of 0.33/yr, a minimum of 0.2/yr, and a maximum of 2.0/yr 
(DTN: MO0407SPAINEXI.002 [DIRS 170597]). For an initial ash depth of 10 mm or more, the 
mass loading decrease constant is represented by a triangular distribution with a mode of 0.20/yr, 
a minimum of 0.125/yr, and a maximum of 1.0/yr (DTN: MO0407SPAINEXI.002 
[DIRS 170597]).

The value of the critical thickness is different for each biosphere model realization and has to be 
sampled in the TSPA code together with the BDCFs from the same vector. 
An alternative method of using the volcanic ash scenario BDCFs can be offered for the situation 
when the radionuclide concentration in the resuspendable layer of surface soil of about 1-3 mm 
thickness (BSC 2004 [DIRS 169672], Section 6.8) is known. If this is the case, the annual dose 
can be calculated as

Equations shown above use SI units for consistency with the documentation of the ERMYN 
model (BSC 2004 [DIRS 169460]). However, any units can be used to define parameters in 
GoldSim, where the ERMYN model is implemented, as long as they are dimensionally 
consistent. The values of BDCF components in the output DTN are given in rem/yr per pCi/m2.

7.1.4 Use of Dose Factors 
For the eruption period, the dose factors for the inhalation exposure pathway should be used 
instead of the BDCFs. The dose factors for evaluating doses during volcanic eruptions are listed 
in Table 6.3-3. To calculate the daily dose from inhaling a specific radionuclide during a 
volcanic eruption, multiply the activity concentration of that radionuclide in air by the 
appropriate dose factors. The total inhalation dose, Dinh, from concentrations of primary 
radionuclides in air is then calculated as 
. .  = =

outdoor i i 
i 
i inh inh Ca DF D D , , (Eq. 7.1-5) 
where 
Dinh, i = daily inhalation dose for a primary radionuclide i (Sv/d or rem/d) 
DFi = dose factor for a primary radionuclide i (Sv/d per Bq/m3 or rem/d per 
pCi/m3) 
Cai,outdoor = activity concentration of a primary radionuclide i in outdoor air for the 
ash that has not yet fallen on the ground (Bq/m3 or pCi/m3). 
7.1.5 Correlations, Pathway Analysis, and Climate Change 
Correlation coefficients for the BDCF components for each individual radionuclide are listed in 
Table 6.2-4. Rank correlations between the BDCF components of different radionuclides also 
have been calculated. Correlation coefficients for the external-ingestion-radon component are 
listed in Table 6.2-5. Correlation coefficients are the highest for the isotopes of actinides. 
Correlation coefficients for short-term and long-term inhalation components are equal to one. 
Results of pathway analysis are presented in Table 6.2-7. The dominant pathway for actinide 
radionuclides is inhalation, with the long-term component contributing about 2/3 of the dose and 
the short-term component contributing about 1/3 of the dose. The pathway contributions for the 
other radionuclides are more diversified. For example, the food consumption pathways are 
dominant for 99Tc, and the external exposure pathway is dominant for 137Cs. 
The climate change during the period of time considered in this analysis has negligible effects on 
the BDCFs for the volcanic ash exposure scenario because it primarily affects parameters related 
to irrigation and water use, which are not included in the model for the volcanic ash exposure 
scenario. It is thus recommended that the present-day climate BDCFs be used for dose 
assessment for the entire period. 
7.2 HOW ACCEPTANCE CRITERIA WERE ADDRESSED 
The primary function of this analysis was to calculate BDCFs for the volcanic ash exposure 
scenario. As noted before, this analysis thus integrates the model (BSC 2004 [169460]) and the 
model input parameters (BSC 2004 [DIRS 169671]; BSC 2004 [DIRS 169672]; BSC 2004 
[DIRS 169673]; BSC 2004 [DIRS 169458]; and BSC 2004 [DIRS 169459]) to produce the 
output of the biosphere model. All acceptance criteria addressed by the model and input 
parameters reports are implicitly included in this analysis and the modeling results. The results 

Disruptive Event Biosphere Dose Conversion Factor Analysis 
ANL-MGR-MD-000003 REV 03 7-7 September 2004 
reflect consideration of the site-specific FEPs, characteristics of the reference biosphere and its 
features, parameter selection and justification, as well as incorporation of uncertainty in the 
model and its input parameters. The model for the volcanic ash exposure scenario is briefly 
described in Section 6.1.5; the model input parameter values, including uncertainty distributions, 
are presented in Section 4.1. 
In addition, the acceptance criteria, identified as applicable to this analysis in Section 4.2, that 
are related to the model abstraction were addressed. The biosphere modeling does not utilize the 
model abstraction step, but rather, the BDCF are calculated as the model output. In this sense, 
the BDCFs, which are the input to the TSPA model, serve as a collapsed model abstraction. 
The uncertainty in the model and its input parameters is propagated onto and reflected in the 
BDCFs through the development of the BDCF vectors representing individual model realizations 
(see Section 7.1.2), consistent with the acceptance criteria 2.2.1.3.13.3, 2.2.1.3.13.4, and 
2.2.1.3.14.3 (see Table 4.2-2). 
The specific acceptance criteria were addressed as follows. 
2.2.1.3.13.3: Redistribution of Radionuclides in Soils 
Acceptance Criterion 1 (1): As discussed in Sections 1 and 7.1.4, because the BDCFs are used 
directly in the TSPA, the TSPA adequately incorporates the redistribution of radionuclides 
contained in soils as a result of volcanic activity. 
Acceptance Criterion 1(2): By including the BDCFs for disruptive events, the TSPA identifies 
and describes an aspect of radionuclide redistribution in soil that is important to repository 
performance. See, Section 7.1.2 and 7.1.3. The technical bases for the volcanic ash exposure 
scenario are adequately described in Section 6.1.2. 
Acceptance Criterion 1 (3): Relevant site FEPs, including climate change (Section 6.1.3), 
receptor characteristics (Section 6.1.4), and the biosphere model (Section 6.1.5) have been 
appropriately modeled in the BDCFs. Sufficient technical bases are provided for the BDCFs. 
Acceptance Criterion 1 (4): This report was developed in accordance with the QA procedures. It 
commits to NUREG-1297 and NUREG-1298. This commitment is implemented in project 
procedures. Compliance with project procedures is assessed through QA audits and other 
oversight activities. 
Acceptance Criterion 2 (1): The BDCF development process described in Section 6 shows that 
the BDCFs used in the license application are justified. Adequate descriptions of how data was 
used to develop BDCFs are presented in Section 6.2, which includes pathway analysis (Section 
6.2.4), climate change (Section 6.2.5), and uncertainty (Section 6.2.1). 
Acceptance Criterion 2 (2): As shown in Sections 4.1.1 and 6.3.1, sufficient data are available to 
adequately define the parameters for the BDCFs. 
Acceptance Criterion 3 (1): The calculations described in Section 6.2.2, the calculation results 
presented in Section 6.2.3, and the development of dose factors described in Section 6.3.2 show 

Disruptive Event Biosphere Dose Conversion Factor Analysis 
ANL-MGR-MD-000003 REV 03 7-8 September 2004 
that the parameter values are technically defensible, reasonably account for uncertainties, and do 
not result in an under-representation of the risk. 
Acceptance Criterion 3 (2): Section 6.3.1 shows that the data on the airborne particulate 
concentration is based on the resuspension of appropriate material in a climate and level of 
disturbance which is expected to be found at the location of the RMEI in the event of a volcanic 
eruption. 
Acceptance Criterion 3 (3): Sections 6.2.1 and 7.1.1 shows that uncertainty was adequately 
represented in the BDCFs by a probability distribution which was generated from a thousand 
realizations using a Monte Carlo technique. 
2.2.1.3.14.3: Biosphere Characteristics 
Acceptance Criterion 1 (3): Section 6.2.6 shows how the impact of climate change on the BDCFs 
is consistent with assumptions about climate change in other TSPA abstractions. 
Acceptance Criterion 1 (4): This report was developed in accordance with the QA procedures. It 
commits to NUREG-1297 and NUREG-1298. This commitment is implemented in project 
procedures. Compliance with project procedures is assessed through QA audits and other 
oversight activities. 
Acceptance Criterion 2 (1): The BDCF development process described in Section 6 shows that 
the BDCFs used in the license application are justified. Adequate descriptions of how data was 
used to develop BDCFs are presented in Section 6.2, which includes a pathway analysis (Section 
6.2.4), climate change (Section 6.2.5), and uncertainty (Section 6.2.1). 
Acceptance Criterion 2 (2): As shown in Sections 4.1.1 and 6.3.1, sufficient data are available to 
adequately define the parameters for the BDCFs. 
Acceptance Criterion 3 (1): Sections 6.2.3, 6.3.2, and 6.1.4 show that the parameter values are 
technically defensible, reasonably account for uncertainties, do not result in an underrepresentation 
of the risk, and are consistent with the definition of the RMEI. 
Acceptance Criterion 3 (2): The technical bases for the BDCFs and inhalation dose factors are 
shown to be technically defensible by the Section 6.3.1 analysis of mass loadings measured at 
volcanic eruptions.

ANALYSIS OF IMPACT OF SOFTWARE AND INPUT CHANGE ON THE 
MODELING RESULTS 

Disruptive Event Biosphere Dose Conversion Factor Analysis 
ANL-MGR-MD-000003 REV 03 September 2004 

Disruptive Event Biosphere Dose Conversion Factor Analysis 
ANL-MGR-MD-000003 REV 03 C-1 September 2004 
This section presents the results of impact analysis regarding the input and software change 
between the Revision 02 of this analysis (BSC 2003 [DIRS 163958]) and the current revision. 
As a result of source data change and other improvements, the input data changed for a few 
model input parameters. Also, an inconsistency was discovered in the Latin Hypercube 
sampling scheme that was used by GoldSim V7.50.100, which was used to execute the biosphere 
model in Revision 02 of this analysis. The inconsistency was corrected in GoldSim V8.01.SP4, 
which was used to generate the volcanic ash exposure scenario BDCFs in this analysis. The 
comparison of the model output using the previous and the current set of the biosphere model 
input parameters is presented in Section C.1. Section C.2 contains an evaluation of impact from 
the GoldSim version update. The combined effect of the input and the software change is not 
evaluated because the impact from the input parameter change is negligible (Section C.1) so the 
overall difference results almost entirely from the software change. 
C1. EVALUATION OF INPUT CHANGE IMPACT ON THE MODELING RESULTS 
The differences between the old and new input data are shown in Section 4.1, Table 4.1-5, 
describing direct inputs for this analysis. The differences in parameter values are very small and 
are limited to the values of cesium transfer factor for leafy vegetables, cesium transfer 
coefficient for eggs and the maximum value of mass loading for the volcanic indoor asleep 
environment. To evaluate the impact of these input changes the BDCFs, the biosphere model 
was executed for 137Cs and 241Am using the new set of input parameters (DTN: 
MO0407SPAINEXI.002 [DIRS 170597], MO0407SPASRPBM.002 [DIRS 170755], 
MO0403SPAAEIBM.002 [DIRS 169392], MO0407SPACRBSM.002 [DIRS 170677], 
MO0406SPAETPBM.002 [DIRS 170150]) and the previously used version of software, i.e. 
GoldSim V7.50.100. 137Cs was selected because the change in cesium transfer factor for leafy 
vegetables and cesium transfer coefficient for eggs only affects the BDCF components for 137Cs. 
Americium-241 was selected because the maximum value of mass loading for the volcanic 
indoor asleep environment could only affect inhalation BDCF components, which are dominant 
components for the actinides, as shown in Table 6.2-7. Since the contributions of the inhalation 
BDCF components are very similar for all actinides (Table 6.2-7), the evaluation of the input 
change impact for only one of them was sufficient. 
Table C.1-1 shows the statistics for the BDCFs for 137Cs generated using the new input 
parameters and compares them to the BDCF statistics for this radionuclide generated using same 
software version with old inputs (DTN: MO0305SPAINEXI.001 [DIRS 163808], 
MO0305SPASRPBM.001 [DIRS 163815], MO0306SPAAEIBM.001 [DIRS 163812], 
MO0306SPACRBSM.001 [DIRS 163813], MO0306SPAETPBM.001 [DIRS 163814]). 
Table C.1-2 shows a similar comparison for 241Am. The results of comparison are expressed in 
terms of percent relative difference between the BDCF statistics. 
The relative differences between the BDCFs resulting from the input change are negligibly 
small, on the order of a fraction of a percent. It can be thus concluded that the BDCF differences 
due to the input value changes are insignificant.

C2. EVALUATION OF SOFTWARE VERSION CHANGE IMPACT ON THE 
MODELING RESULTS 
This section describes the assessment of the differences in the BDCF values resulting from the 
software change. The software used to calculate BDCFs in the previous revision of this analysis 
(BSC 2003 [DIRS 163958]) was GoldSim V7.50.100. This version was subsequently replaced 
with the GoldSim V8.01 SP4, which uses revised sampling algorithm for the Latin Hypercube 
sampling. Evaluation of the sampling algorithm effects on the biosphere model results was 
performed and is documented in this section. This evaluation corresponds to the Action 001 in 
CR-2222. The following steps were delineated in the action description: 
1. Using GoldSim V8.01 SP4 or higher, rerun all biospheres analyses that rely on Latin 
Hypercube Sampling (LHS) for selecting parameter-input values. 
2. Compare the outputs from these runs with outputs from earlier versions of GoldSim 
used in the analysis and model reports. 
3. Determine the amount of variation between the two outputs for the mean, 95th 
percentile, and 5th percentile values. 
4. If the variation is less than 10 percent document the results of the comparison and 
submit the documentation to the records package for the analysis and model reports. 
5. If the variation is greater than 10 percent then submit the revised outputs to TSPA to 
evaluate the impact of the variation on the TSPA results. 
6. Perform TSPA calculations with GoldSim V8.01 SP4 or higher using the revised 
inputs. 
To evaluate the impact on the BDCFs, the biosphere model was executed using GoldSim V8.01 
SP4 and the old set of input parameters (DTN: MO0305SPAINEXI.001 [DIRS 163808], 
MO0305SPASRPBM.001 [DIRS 163815], MO0306SPAAEIBM.001 [DIRS 163812], 
MO0306SPACRBSM.001 [DIRS 163813], MO0306SPAETPBM.001 [DIRS 163814]). 
Tables C.2-1 to C.2-3 show the statistics for the BDCF generated in such a manner for the three 
BDCF components. These statistics were compared to the statistics for the BDCFs generated 
using GoldSim V7.50.100 and the old input parameter values, which are shown in Tables C.2-4 
to C.2-6). The results of comparison in terms of percent relative difference between the BDCF 
calculated using the two different version of GoldSim are presented in Tables C.2-7 to C.2-9 for 
the external/ingestion/radon, short-term inhalation, and long-term inhalation BDCF components, 
respectively. 
The relative differences between the BDCFs resulting from the software change are relatively 
small. For the inhalation components, the differences between the BDCFs calculated using 
different version of GoldSim are almost the same for all radionuclides. For these components, 
the differences between the mean values are around 1 percent or less, and the differences for the 

Disruptive Event Biosphere Dose Conversion Factor Analysis 
ANL-MGR-MD-000003 REV 03 C-5 September 2004 
5th percentile and the 95th percentile values are less than 7 percent. For the 
external/ingestion/radon components, the differences between the BDCF calculated using 
different GoldSim versions depend on the radionuclide. Still, the mean values do not differ by 
more than 7 percent and the differences for the 5th percentile and the 95th percentile values 
exceed 10 percent for only one radionuclide, 237Np, were the relative difference is less than 
24 percent. The standard deviations, minimum and maximum values seem to be the most 
affected by the software change. 
Because there was an instance when the variation between the results obtained using different 
GoldSim versions exceeded the 10 percent threshold for the statistics listed in step 3 of the 
Action 001 in CR-2222, step 5 was performed and new biosphere results were generated, as 
described in this report.

C3. EVALUATION OF INPUT AND SOFTWARE VERSION CHANGE IMPACT ON 
THE MODELING RESULTS 
This section describes the evaluation of the combined differences in the BDCF values resulting 
from the input and software change. In doing so, the new BDCFs developed in this analysis are 
compared to the BDCFs developed in the previous revision of the analysis and the differences 
are evaluated. 
The differences resulting from the input changes are described in Section C.1; the differences 
resulting from the software changes are described in Section C.2. As stated in Section C.1, the 
relative differences between the BDCFs resulting from the input change are negligibly small, on 
the order of a fraction of a percent, and the input changes concern only one element, cesium, and 
one pathway, short-term inhalation, for all radionuclides. It can be thus concluded that the 
BDCF differences are only due to the software changes. 
Tables C.2-7 to C.2-9 show that the differences between the values of BDCF components are 
small. For most radionuclides, inhalation of particular matter is a dominant exposure pathway 
(Table 6.2-7). The mean values of the inhalation components for all radionuclides differ by just 
0.03 percent for the long-term inhalation component (a more important component in the 
calculations of the expected dose from a volcanic eruption) and by 1.04 percent for the 
short-term inhalation component. The differences in the statistics between 5th and 95th 
percentile are less than a few percent. Only the far tails of the distributions are affected, with the 
differences up to about 20 percent. 
For the external exposure, ingestion, and radon BDCF component, the differences in the mean 
values are radionuclide-dependent and are less than 7 percent. The differences in the percentiles 
of the distribution between 5th and 95th percentile are less than ten percent for all radionuclides 
except 237Np. However, for this radionuclide, the inhalation pathway is dominant and the 
contribution of the external exposure and ingestion to the all-pathway dose is negligible. 
It can thus be concluded that the differences between the BDCFs calculated in the previous 
revision of this analysis and the new BDCFs developed in this analysis are equivalent and can be 
used interchangeably.

The ERMYN model for the volcanic ash exposure scenario (DTN: MO0306MWDBGSMF.001 
[DIRS 163816]) was constructed and verified for GoldSim V7.50.100. Verification was 
conducted for two radionuclides: 226Ra, and 239Pu because these two radionuclides are 
representative of all environmental transport and exposure pathways included in the model for 
the volcanic ash exposure scenario. To verify the applicability of GoldSim V8.01 SP4 as 
software supporting the biosphere model, the original model verification files were opened in 
GoldSim V8.01 SP4 and the verification calculations were repeated. 
Figure E-1 shows the list of the original verification files as well as the model files generated in 
this analysis when the original files were run using GoldSim V8.01 SP4. Table E-1 shows the 
results from the original verification files and their re-runs in GoldSim V8.01 SP4. The results 
are identical, so the model can be executed using GoldSim V8.01 SP4.
