EXECUTIVE SUMMARY

In the National Institute for Occupational Safety and Health’s (NIOSH’s) evaluation report (ER) 

for the Idaho National Laboratory (INL) Special Exposure Cohort (SEC) petition SEC-00219 of 

March 12, 2015 (NIOSH 2015), one of the major assumptions was that a bioassayed indictor 

radionuclide (strontium-90 [Sr-90] and/or cesium-137 [Cs-137]) can be used to assign 

dosimetric-significant fission and activation product (FAP) and actinide (alpha emitter) intakes 

using the ratio method. This method requires that radionuclide ratios remain fairly constant for 

the many processes and locations, and over most of the operating history of INL. However, 

SC&A found that apparently most of the radionuclide ratios recommended by NIOSH were 

generated by computer modeling, and that there was no indication that the computer-generated 

ratio values had been compared to ratio values derived from physical measurement.

In view of INL’s many types of reactors, its experimental charter, and the various fuels and 

materials shipped in from other sites for processing, SC&A performed a preliminary analysis of 

some of the available INL bioassay, Brookhaven National Laboratory fuel, and swipe data in 

2015 to obtain an indication of the validity of this assumption (SC&A 2015). As outlined in that 

report, SC&A found there were indications that the Cs-137/Sr-90 values were not always 

centered on unity. SC&A then searched for documentation of quantitative analyses of the fuel 

elements processed in the dissolver at the Idaho Chemical Processing Plant in order to determine 

the radionuclide components that workers may have been exposed to; however, such 

documentation has not been located to date. Therefore, SC&A searched the Site Research 

Database for other documents that could provide quantitative radionuclide data. During this 

search, SC&A located many INL waste reports that contained quantitative Cs-137 and Sr-90 

measurements performed on the same samples (some also contained FAP and actinide analyses); 

these reports spanned a relatively long time period (1961–1998) for the major operational areas 

within INL. Quantitative radionuclide data for waste materials (air, liquid, and solid) at the INL 

facilities provide a good representation of the potential intake exposures to workers. Therefore, 

these data were analyzed in detail to evaluate if there is a reasonably consistent relationship 

between the Cs-137/Sr-90 concentrations, and if these indicating radionuclides could be used to 

assign other radionuclide intakes such as FAP for dose reconstruction (DR) purposes. In 

addition, quantitative actinide data in relationship to Sr-90 and Cs-137 were analyzed when 

available. Data for this report included both monthly and annual radionuclide concentrations. A 

former SC&A report analyzed mostly annual radionuclide concentrations (SC&A 2016). 

Cs-137/Sr-90 

A total of 315 monthly and 77 annual matched pairs of measured Cs-137 and Sr-90 activities 

were located and analyzed, spanning the period 1961–1998 for a number of major facilities at the 

INL site. Of these matched data pairs, approximately 45% contained Cs-137/Sr-90 values 

centered on unity, within a factor of 2 (i.e., Cs-137/Sr-90 = 0.5 to 2.0) for both monthly and 

annual data pairs (there were no outstanding differences between monthly and annual pair 

ratios). The remaining Cs-137/Sr-90 values were outside this interval, with values ranging from 

0.03 to 159. Similar results were obtained for Sr-90/Cs-137 values, with the ratio values being 

the inverse of the Cs-137/Sr-90 ratio values. Cs-137 activities were generally slightly greater 

than Sr-90 activities.

Fission and Activation Product Ratios 

A total of 280 monthly and 103 annual matched pairs of measured Sr-90 and FAP (cerium-144 

[Ce-144], cobalt-60 [Co-60], and ruthenium-106 [Ru-106]) activity were located and analyzed, 

spanning the period 1961–1995 for various facilities at the INL site. The measured FAP/Sr 

values were compared to the FAP/Sr values recommended in Table 7-3a (with a one-year decay 

time) of ORAUT-OTIB-0054, Fission and Activation Product Assignment for Internal DoseRelated Gross Beta and Gross Gamma Analyses, Revision 03, dated February 6, 2015. A 

comparison ratio value centered on 1.0 would indicate agreement between the measured and 

recommended values; however, ratio values not centered on unity would indicate insufficient or 

excessive FAP intake assignments during DR. Of these matched pairs, measured Ce-144/Sr-90 

values generally fell below the recommended ratio of 12.5, measured Co-60/Sr-90 values almost 

always were greater than the recommended value of 1.8E-4, and measured Ru-106/Sr-90 values 

tended to be at or below the recommended ratio of approximately 1.0 (there were no outstanding 

differences between monthly and annual pair ratios for these FAPs). Similar results were 

obtained using FAP/Cs-137 data. 

Actinide Ratios 

A total of 56 monthly and 13 annual matched pairs of measured Sr-90 and an actinide 

(americium-241 [Am-241], plutonium-238 [Pu-238], and uranium-234 [U-234]) activity were 

located and analyzed, spanning the period 1974–1993 for various facilities at the INL site. The 

measured actinide/Sr values were compared to the actinide/Sr values recommended in 

Table 5-22 of ORAUT-TKBS-0007-5, Idaho National Laboratory and Argonne National 

Laboratory – West – Occupational Internal Dose, Revision 03, dated March 2, 2010. A 

comparison ratio value centered on 1.0 would indicate agreement between the measured and 

recommended values; however, ratio values not centered on unity would indicate insufficient or 

excessive actinide intake assignments during DR. Of these matched pairs, most of the measured 

actinide-to-Sr-90 ratios were greater, and a few were less, than the recommended value, with 

considerable scatter and relatively few values falling within the 0.5 to 2.0 ratio range. The 

measured Pu-238 (the most significant radionuclide for internal actinide doses)-to-Sr-90 ratio 

had the most recorded data points, compared to the other actinides, but with ratio values that had 

considerable scatter and fairly poor statistical correlation. Similar results were obtained using 

actinide/Cs-137 data. 

Conclusions

These results indicate that at INL, the Cs-137/Sr-90 values may not be centered on unity as 

indicated in ORAUT-OTIB-0054, Revision 03, and some FAP/Sr and FAP/Cs measured values 

may be greater or less than recommended for assigning FAP intakes. Also, actinide/Sr or 

actinide/Cs values may not be sufficiently constant (or known) as required by ORAUT-TKBS0007-5 (Tables 5-22 and 5-23) for assigning actinide intakes, even in situations where it can be 

assumed that the actinides are tied to an indicating radionuclide, such as Sr-90 or Cs-137. 

Therefore, SC&A finds:

1. Cs-137/Sr-90 values are not sufficiently constant to assume a ratio of unity. Using the 

results of Cs-137 bioassays versus Sr-90 bioassays may lead to differences in FAP intake 

assignments for the radionuclides listed in Table 7-3 of ORAUT-OTIB-0054, 

Revision 03, for DR.

2. Measured Ce-144/Sr-90 or Ce-144/Cs-137 values indicate that the recommended values 

in Table 7-3 of ORAUT-OTIB-0054, Revision 03, are reasonable for DR purposes.

3. Measured Co-60/Sr-90 or Co-60/Cs-137 values are not in agreement with the 

recommended values in Table 7-3 of ORAUT-OTIB-0054, Revision 03. Using the 

recommended ratio values would usually lead to significant underestimation of Co-60 

intake for the waste materials analyzed in this report.

4. Measured Ru-106/Sr-90 or Ru-106/Cs-137 values indicate that the recommended values 

in Table 7-3 of ORAUT-OTIB-0054, Revision 03, are generally reasonable for DR 

purposes, but there was noticeable scatter in the measured ratio values. 

5. Measured FAP ratio values could only be obtained for relatively long-lived radionuclides 

(Cs-137, Sr-90, Ce-144, Co-60, and Ru-106). Therefore, the actual ratio values for the 

short-lived FAPs in Table 7-3 of ORAUT-OTIB-0054, Revision 03, are not known at this 

time for the material analyzed. 

6. Measured actinide/Sr-90 or actinide/Cs-137 values are difficult to obtain because FAPs 

are generally not analyzed when actinide samples are taken. The relatively few data pairs 

obtained for this study indicate that for the three most dose-contributing radionuclides 

(Pu-238, Am-241, and U-234), the measured actinide/Sr-90 or actinide/Cs-137 values 

were generally greater than the recommended values in Tables 5-22 and 5-23 of 

ORAUT-TKBS-007-5, Revision 03, some by a significant amount.

1.0 INTRODUCTION AND BACKGROUND 

The National Institute for Occupational Safety and Health (NIOSH) responded to the Idaho 

National Laboratory (INL) Special Exposure Cohort (SEC)-00219 in an evaluation report (ER) 

of March 12, 2015 (NIOSH 2015). In that ER, and also in the technical basis document for INL, 

ORAUT-TKBS-0007-5, Revision 03, Idaho National Laboratory and Argonne National 

Laboratory – Occupational Internal Dose, issued March 2010, NIOSH’s basis for assigning 

internal intakes/doses for most years and locations at INL (except those actinides covered by 

NIOSH’s proposed SEC class and the reserved areas and dates) relies on the important 

assumption that the cesium-137/strontium-90 (Cs-137/Sr-90) values are approximately unity, 

that fission activation products (FAPs) are directly tied by a known ratio to Sr-90 or Cs-137 (as 

per ORAUT-OTIB-0054, Fission and Activation Product Assignment for Internal Dose-Related 

Gross Beta and Gross Gamma Analyses [also referred to as “OTIB-0054”]1), and that actinides 

are directly tied by a known ratio to Sr-90 or Cs-137 (as per Tables 5-22 and 5-23 of ORAUTTKBS-0007-5, Revision 03). However, SC&A found that apparently most of the radionuclide 

ratios recommended by NIOSH were generated by computer modeling, and that there was no 

indication that the computer-generated ratio values had been compared to ratio values derived 

from physical measurement. 

1 For this analysis, SC&A used ORAUT-OTIB-0054, Revision 03 of February 6, 2015. For Cases A and D, NIOSH 

used ORAUT-OTIB-0054, Revision 00 PC-1 of November 19, 2007; for Case B, NIOSH used Revision 02 of

March 6, 2014; and for Case C, NIOSH used Revision 03 of February 6, 2015.

In a previous evaluation using a relatively small sampling of bioassay and swipe data 

(SC&A 2015), SC&A found indications that the measured Cs-137/Sr-90 values were not always 

centered on unity, and that the measured FAP/Sr, FAP/Cs, actinide/Sr, and actinide/Cs values 

were not constant or necessarily representative of those recommended in ORAUT-TKBS-0007-

5, Revision 03. Therefore, SC&A searched for further documentation of measured quantitative 

radionuclide analyses of Sr-90, Cs-137, FAP, and actinide activities. Searches for documentation 

of quantitative analyses of the fuel elements processed in the dissolver at the Idaho Chemical 

Processing Plant have not produced significant data to date. 

In the process of searching the Site Research Database (SRDB), SC&A located INL waste 

management reports that contained quantitative Sr-90 and Cs-137 measurements performed on 

the same samples (some also contained FAP and actinide data). These reports span a relatively 

long time period (1961–1998) and cover a number of the major operational areas within INL. 

These data provide a good representation of the materials workers could have been exposed to, 

and the potential intake mixtures. SC&A analyzed annual and one-of-a-kind (i.e., point sample) 

radionuclide pairs in a report issued in June 2016 (SC&A 2016). In response to Work Group 

tasking at the joint INL/Argonne National Laboratory-West meeting held in August 2016, SC&A 

prepared this latest report. In this report, SC&A analyzed both monthly and corresponding 

annual data pairs to determine if the measured-to-recommended ratio values were useful for dose 

reconstruction (DR) purposes, and to determine if there is any difference in resulting ratios using 

monthly versus annual activity data. A list of the documents that contained useful radionuclide 

measures and some of the recorded data that were used in this evaluation are provided in this

actinide). Analyses of these data are provided in the following sections. 

2.0 Cs-137/Sr-90 VALUES

NIOSH’s ER and ORAUT-TKBS-0007-5, Revision 03, rely heavily on the use of ORAUTOTIB-00542

 to assign FAP intakes using Sr-90 or Cs-137 as the indicating radionuclide for 

many other FAP radionuclides at INL for most locations and time periods. An example of Table 

7-3a from ORAUT-OTIB-0054, Revision 03, is provided here as Figure 1. As can be seen from 

this table, assignment of FAP intakes is dependent on the Cs-137/Sr-90 value being 

approximately 1.0. 

2 NIOSH’s ER cites ORAUT-OTIB-0054, Revision 02 of March 6, 2014. ORAUT-TKBS-0007-5 cites ORAUTOTIB-0054, Revision 00 PC-1 of November 19, 2007.

Figure 1. Table 7-3a, FAP-to-Sr-90 or -Cs-137 Ratios for ATR-1 (ORAUT-OTIB-0054) 

SC&A located a total of 315 monthly and 77 annual matched pairs of measured Cs-137 and 

Sr-90 activity in the INL waste reports, spanning the period 1961–1998 for the INL site. SC&A 

analyzed these data to determine the Cs-137/Sr-90 values for each matched pair for the INL site. 

Only recorded and paired data points specifically listing Cs-137 and Sr-90 in units of activity 

(microcurie [μCi], curie [Ci], etc.) on the same material were used in these analyses; this 

included air, liquid, and solid waste. Figures 2 and 3 contain the results for the 315 monthly 

(represented by orange squares) and 77 annual (represented by blue diamonds) INL data pairs 

analyzed.

Figures 2 and 3, and 59.7% falling within a factor of 3 (i.e., 0.33 to 3.0). The remaining ratio 

values were outside these intervals with values ranging from 0.03 to 159. Table 1 summarizes 

the distribution of the ratios that fell below, within, and above the recommended ratio by a factor

As can be seen from Table 1, there were no outstanding differences using monthly data as 

compared to using annual data to derive the Cs/Sr and Sr/Cs ratio values in these analyses. Also, 

the ratio values derived using monthly and annual activity data pairs in these analyses were 

similar to those obtained using only annual data in the June 2016 report (SC&A 2016), where 

251 data pairs resulted in 33% of the ratio values falling in the 0.5 to 2.0 interval. The results 

obtained in these analyses, those contained in SC&A’s June 2016 report (SC&A 2016), and 

those contained in SC&A’s November 2015 report (SC&A 2015) were similar. 

Figures 4 and 5 show the ratio values derived from the measured monthly and annual data 

compared to NIOSH’s recommended ratios. The black bar inside the smaller shaded rectangle

(gray) represents a central estimate of the value of the ratio from measured pairs (with the 

smaller shaded rectangle representing the 95% confidence interval3 of the central estimate of the 

value of the ratio from measured pairs). The center horizontal red line inside the larger shaded 

rectangle (pink) represents the NIOSH-recommended ratio value of approximately 1.0. The 

larger shaded rectangle represents the recommended ratio value, + a factor of 3.

 

3 The smaller shaded rectangle (gray) represents the 95% confidence interval of the center estimate of the ratio value 

derived from statistical analyses, which is different from the 95% confidence level of the original data in the data 

pairs.

a factor of 3, there was considerable scatter of the ratio values over a wide range, as shown in 

Figures 2 and 3. 

3.0 FAP/Sr-90 VALUES

Although a large number of radionuclides are listed in Table 7-3 of ORAUT-OTIB-0054, 

Revision 03, many have relatively short half-lives (compared to the time from when the 

radionuclide was created until the time the waste sample was analyzed); therefore, when 

analyzing the INL waste reports, only those with relatively long half-lives (equal to or greater 

than approximately 1 year) were selected for analysis. A total of 280 monthly and 103 annual 

matched pairs of measured Sr-90 and FAP (cerium-144 [Ce-144], cobalt-60 [Co-60], and 

ruthenium-106 [Ru-106]) activities were located and analyzed, spanning the period 1961–1995 

for various facilities at the INL site. The measured FAP/Sr values were compared to the FAP/Sr 

values recommended in Table 7-3a (with a one-year decay time) of ORAUT-OTIB-0054, 

Revision 03. A comparison ratio value centered on 1.0 would indicate agreement between the 

measured and recommended values; however, ratio values not centered on unity would indicate 

insufficient or excessive FAP intake assignments during DR. Figures 6 through 8 contain the 

results for the 280 monthly (represented by orange squares) and 103 annual (represented by blue 

diamonds) FAP INL data pairs analyzed.

As can be seen from Table 2, there were no outstanding differences using monthly data as 

compared to using annual data to derive the FAP/Sr and FAP/Cs ratio values in these analyses. 

Measured Ce-144/Sr-90 values generally fell below the recommended ratio of 12.3, measured 

Co-60/Sr-90 values were almost always greater than the recommended value of 1.8E-4, and 

measured Ru-106/Sr-90 values tended to be near or below the recommended ratio of 1.0. Similar 

results were obtained for FAP/Cs-137 values. 

Figures 9 through 11 show the ratio values derived from the measured monthly and annual data 

compared to NIOSH’s recommended ratios. The black bar inside the smaller shaded rectangle

(gray) represents a central estimate of the value of the ratio from measured pairs (with the

smaller shaded rectangle representing the 95% confidence interval of the central estimate of the 

value of the ratio from measured pairs). The center horizontal red line inside the larger shaded 

rectangle (pink) represents the NIOSH-recommended ratio value. The larger shaded rectangle

represents the recommended ratio value, + a factor of 3.

4.0 FAP CONTRIBUTION TO INTERNAL DOSE 

To determine the impact that FAP intake values and the resulting doses have on the total internal 

dose assignments, SC&A analyzed the FAP doses in four DR cases (A, B, C, and D4) obtained 

from the NIOSH OCAS Claims Tracking System (NOCTS). These cases were selected because 

they each had both FAP intakes assigned using ORAUT-OTIB-00545

 and actinide intakes 

assigned using ORAUT-TKBS-0007-5, Revision 03, Tables 5-22 and 5-23, and included major 

organs of interest. Table 3 summarizes this analysis.

4 A, B, C, and D are not the actual NOCTS claim numbers for these cases. They are placeholders assigned to these 

cases only for use in this analysis. 5 For Cases A and D, NIOSH used ORAUT-OTIB-0054, Revision 00 PC-1 of November 19, 2007; for Case B, 

NIOSH used Revision 02 of March 6, 2014; and for Case C, NIOSH used Revision 03 of February 6, 2015.

D Sr-90 Skin 0.616 0.570 92.5%

D Sr-90 Kidney 0.827 0.700 84.6%

As can be seen from Table 3, FAP doses contribute significantly to the total internal dose, and 

differences in the FAP to Sr-90 or to Cs-137 values used could impact the total dose assigned 

and resulting probability of causation (POC) value. Therefore, there should be reasonable 

agreement among Sr-90 and Cs-137 ratios and among other FAP-to-Sr-90 or to-Cs-137 ratios. 

Tables 4a and 4b provide the six largest contributors to these organ doses of the 17 FAPs listed

in ORAUT-OTIB-0054, Revision 03. The top six contributors were selected for illustration 

because they constitute 80% to 95% of the total FAP internal dose assigned, depending on the 

organ.

These results indicate that a variety of FAP radionuclides are important in assigning FAP internal 

doses, depending on the organ of interest. Therefore, most of the FAP-to-Sr-90 or to-Cs-137 

ratio values are important for FAP dose assignment, and there should be reasonable agreement 

among Sr-90 and Cs-137 ratios and among other FAP-to-Sr-90 or to-Cs-137 ratios for adequate 

and consistent dose assignments.

5.0 ACTINIDE/Sr-90 VALUES

According to NIOSH’s ER, the basis for assigning actinide intakes, except for special situations, 

is directly tied (in a constant ratio) to an indicating radionuclide (Sr-90 or Cs-137) using 

Table 5-22 (Sr-90 ratios) and/or Table 5-23 (Cs-137 ratios) of ORAUT-TKBS-0007-5, 

Revision 03. These tables are reproduced here as Figures 12 and 13.

Figure 13. Table 5-23, Actinide-to-Cs-137 Ratios (ORAUT-TKBS-0007-5, Revision 03) 

Because this method involves assigning actinide intakes and doses over a long time span and 

many areas and operations, it results in the majority of the internal alpha dose assignments for 

INL workers who did not have specific actinide radionuclide bioassays. Therefore, SC&A used 

measured actinide/Sr-90 and actinide/Cs-137 values to determine if the ratio values 

recommended in Tables 5-22 and 5-23, respectively, are applicable to DR for INL workers. The 

major dose-contributing radionuclides in these tables are americium-241 (Am-241), 

plutonium-238 (Pu-238), Pu-239, uranium-234 (U-234), and U-236; therefore, these were the 

radionuclides searched for in this analysis (with emphases on Pu-238, Am-241, and U-234, the 

largest of the dose contributors). SC&A found that there were not significant analyses for 

actinides in the waste reports until around the mid-1970s, and actinides were many times not

included in the waste reports even in the 1970s and afterwards. For the actinides that were

available, SC&A determined the value of the measured actinide/Sr-90 (or actinide/Cs-137) and 

compared that value to the recommended value in Table 5-22 (or Table 5-23) to obtain a relative 

ratio. A relative ratio centered on unity indicates that the measured value is in agreement with the 

recommended value. A ratio >1.0 indicates that the measured value would assign an intake 

greater than that recommended in the tables, and a ratio <1.0 indicates that the measured value 

would assign an intake less than that recommended in the tables. 

SC&A analyzed the INL waste report data for monthly and annual radionuclide activity 

concentrations. Only recorded and paired data points specifically listing an actinide and 

associated Sr-90 and Cs-137 in units of activity (μCi, Ci, etc.) on the same material were used in 

this analysis; this included air, liquid, and solid waste. Figure 14 contains the results for the 

Pu-238/Sr-90 data pairs analyzed.

In this case, 32.5% of 40 monthly and 12.5% of eight annual Pu-238/Sr-90 data pairs fell within 

the 0.5 to 2.0 range; the other ratios had a wide range of values. Similar results were obtained for 

Pu-238/Cs-137 ratios.

Figure 16. Measured U-234/Sr-90 Values Compared to Ratio Values in 

Table 5-22 from ORAUT-TKBS-0007-5, Revision 03 

In this case, 11.1% of the nine monthly and none of the three annual U-234/Sr-90 data pairs fell 

within the 0.5 to 2.0 range; the other ratios had a wide range of values (one monthly U-234/Sr-90 

value is off this chart at 2.2E-07). Similar results were obtained for U-234/Cs-137 ratios. 

Table 5 summarizes the results using INL monthly and annual data pairs for the three most 

important actinide radionuclides evaluated.

The most important actinide dose contributor of the radionuclides listed in ORAUT-TKBS-0007-

5, Tables 5-22 and 5-23, is Pu-238 (see the next section for details). For the 40 monthly Pu-238 

data pairs, the measured ratio compared to the recommended ratio fell within the interval of 0.5 

to 2.0 32.5% of the time, the measured ratio was greater than the recommended ratio 42.5% of 

the time, and the measured ratio was less than the recommended ratio 25% of the time. There 

were fewer (eight) annual Pu-238 data pairs, but those showed the same trend. Similar results 

were obtained for actinide/Cs-137 ratios. 

6.0 ACTINIDE CONTRIBUTION TO INTERNAL DOSE

To determine the effect actinide intake values, and the resulting doses, have on the total internal 

dose assignment, SC&A analyzed the actinide doses in the four DR cases (A, B, C, and D as 

previously discussed in this report). Table 6 summarizes this analysis.

D Sr-90 Skin 0.616 0.046 7.5%

D Sr-90 Kidney 0.827 0.127 15.4%

As can be seen from this table, actinide doses contribute significantly to the total internal dose in 

some cases. Therefore, differences in actinide-to-Sr-90 or to-Cs-137 ratio values used could 

impact the total dose assigned and the resulting POC value. 

The largest contributor to organ dose of the eight actinides listed in Tables 5-22 and 5-23 of 

ORAUT-TKBS-0007 was Pu-238, followed by Am-241; the other six radionuclides accounted 

for the remaining actinide doses. Table 7 summarizes the percent of the individual radionuclide 

actinide dose compared to the total actinide dose assigned for each organ.

D Skin 97.7% 0.3% 2.0%

D Kidney 96.5% 2.2% 1.3%

These results indicate that plutonium and americium radionuclides are most important in

assigning actinide internal doses when using ORAUT-TKBS-0007-5 for these organs, with 

Pu-238 contributing an average of 97% of the actinide internal dose for the organs in this 

analysis. Therefore, the Pu-238 and Am-241-to-Sr-90 or to-Cs-137 ratio values are important for 

actinide dose assignments, and there should be reasonable agreement among Sr-90 and Cs-137 

ratios and among Pu-238- and Am-241-to-Sr-90 or to-Cs-137 ratios for adequate and consistent 

dose assignments. 

7.0 SUMMARY AND CONCLUSIONS 

The following list summarizes the results based on the measured data points analyzed to date and 

SC&A’s conclusions about those results: 

• Cs-137/Sr-90 – Many of the Cs-137/Sr-90 values were not centered on unity; 45.7% of 

315 monthly data points analyzed for Cs-137/Sr-90 from the 1961–1998 INL waste 

reports fell within a range of 0.5 to 2.0, and 59.7% fell within a range of 0.33 to 3.0, of 

the recommended ratio of 1.0. Some ratio values were several orders of magnitude above 

or below unity (similar results were obtained for annual data pairs). There were no

outstanding differences in using monthly and annual data pairs for determining the 

Cs-137/Sr-90 ratios. Sr-90/Cs-137 results were similar. Therefore, SC&A finds that the 

measured Cs-137/Sr-90 values are not sufficiently constant to assume a ratio of unity. 

Differences in FAP intake assignments during DR for the radionuclides listed in 

Table 7-3 of ORAUT-OTIB-0054 could occur depending on whether Cs-137 bioassays 

or Sr-90 bioassays were performed. 

• FAP/Sr-90 – The analyses of a total of 280 monthly and 103 annual measured FAP/Sr-90 

and FAP/Cs-137 data pairs provided the following results: 

– Ce-144: The majority (average of 95%) of the measured Ce-144/Sr-90 values 

were below a factor of 2 of the recommended ratio value of 12.5; Ce-144/Cs-137 

results were similar. Therefore, SC&A finds that the use of the recommended 

Ce-144 ratios are reasonable for DR purposes.

Privacy Act 5 U.S.C. § 552a and has been cleared for distribution.

– Co-60: Almost all measured Co-60/Sr-90 and Co-60/Cs-137 values were greater 

than the recommended value of 1.8E-4, with many values orders of magnitude 

greater. Therefore, SC&A finds that the use of the recommended ratio of 1.8E-4 

would result in significant under assignment of Co-60 intakes for much of the 

materials analyzed in this report.

– Ru-106: Many (average of 76%) of the Ru-106/Sr-90 values were near the 

recommended ratio value of approximately 1.0, within a factor of 2; 

Ru-106/Cs-137 results were similar. Therefore, SC&A finds that the use of the 

recommended Ru-106 ratios are generally reasonable for DR purposes, but there 

was noticeable scatter in the measured ratio values. 

– Measured FAP ratio values could only be obtained for relatively long-lived 

radionuclides (Cs-137, Sr-90, Ce-144, Co-60, and Ru-106). Therefore, the actual 

ratio values for the shorter-lived FAPs in Table 7-3 are not known at this time for 

the material analyzed.

• Actinide ratios – Many of the measured actinide to Sr-90 or Cs-137 values were greater, 

and a few were less, than the recommended values in ORAUT-TKBS-0007-5, 

Tables 5-22 and 5-23. Some ratios were orders of magnitude above, and a few were 

orders of magnitude below, those recommended, with considerable scatter. Relatively 

few values fell within the 0.5 to 2.0 ratio (or the 0.33 to 3.0 ratio) range. For the most 

important (from a dose consideration) radionuclide, Pu-238, an average of 48% of the 

total 40 monthly and 8 annual measured Pu-238 to Sr-90 values compared to the 

recommended value of 1.5E-2 were equal to or below the recommended value within a 

factor of 2.0. Similar results were obtained for Am-241 and U-234, but there were fewer 

data pairs and much more scatter in the ratio values. Actinide/Cs-137 results were 

similar. SC&A found that measured actinide/Sr-90 or actinide/Cs-137 values are difficult 

to obtain, because FAPs are generally not analyzed when actinide samples are taken.

Therefore, verification of the actinide ratios is not feasible from the data analyzed. 

• Use of only Sr-90 or Cs-137 – Evaluation of the many data pairs and radionuclide 

combinations indicates that the sole use of Sr-90 or Cs-137 does not offer an advantage in 

consistency when assigning FAP or actinide intakes. In addition, many bioassays only 

analyzed for Cs-137 or Sr-90, not both. 

• Monthly versus annual data – Comparing the results obtained from using monthly and 

annual data in the waste reports to those obtained previously using bioassays, 

Brookhaven National Laboratory fuels, and smears (SC&A 2015) and those using mostly 

annual data (SC&A 2016) indicates similar results. There did not appear to be any 

outstanding differences in the resulting ratio values when using monthly compared to 

using annual data for the material analyzed for this report.
