Statement of Work 

Purpose and Description of Work: 

The contractor shall evaluate whether or not the reconstruction of dose provides a reasonable 

estimate of the dose (as needed to adjudicate the claim). The contractor shall evaluate and 

recommend whether or not the assumptions (individual case assumptions and assumptions 

applicable to multiple cases) made for dose reconstruction are appropriate and defensible for 

purposes of this program. The contractor shall evaluate whether or not the data from DOE or 

other sources is of sufficient quality necessary to obtain a reasonable estimate of dose. The 

contractor shall evaluate whether or not the dose reconstruction was performed fairly using 

NIOSH guidelines and in a manner consistent with other cases. 

The contractor shall review all relevant dose reconstruction methodologies and/or procedures 

employed by NIOSH I NIOSH contractors in conducting individual dose reconstructions. The 

contractor shall evaluate whether methodologies and procedures are consistent with requirements 

under 42 CFR 82 and whether there are sufficient procedures to achieve consistent application of 

the requirements in 42 CFR 82. 

The contractor shall conduct one of three different levels of review on the selected cases: 1) 

Basic Review, 2) Advanced Review, or 3) Blind Review. The level of review will be determined 

by the Advisory Board. The number of individual dose reconstruction reviews is estimated to be 

approximately 62 during the 6 month performance period ofthis task. It is expected that there 

will be approximately 40 Basic Review cases, 20 Advanced Review cases and 2 Blind Review 

cases. The Board shall select all cases for these reviews. 

Details outlining the approach for each type of review are shown below: 

1. Basic Review 

A. Review Data Collection 

1. Evaluate whether NIOSH received all requested data for the DOE or A WE site 

from any relevant data source or repository 

2. Evaluate whether the data used by NIOSH for the case was adequate to make a 

determination with regard to probability of causation.

B. Review Interview and Documentation provided by claimant 

1. Evaluate whether NIOSH appropriately addressed all of the reported work history 

and events represented by the claimant including but not limited to a) incidents or 

occurrences, b) actual monitoring practices, c) personal protection practices, and 

d) work practices 

2. Assure that interview information is consistent with data used for the dose 

estimate, and if not, evaluate whether reasonable justification is provided. 

C. Review futernal and External Dose Estimates 

1. Evaluate whether all assumptions used in the dose determination ~re appropriate 

for a remedial compensation program and whether the benefit of the doubt was 

resolved in favor of the claimant 

2. Verify dose calculations are appropriate for purposes of determination ofPOC 

3. Evaluate whether the data were consistent with site radiological monitoring 

protocols of the time period. 

4. Evaluate the treatment of 'missed dose' and/or 'unrnonitored dose' if relevant to 

the case. 

5. The review of each dose reconstruction shall include an evaluation of all relevant 

portions of the methods and/or procedures used by NIOSH. This includes, but is 

not limited to: 

a) Review the internal and external radiation dose reconstruction technical 

basis documents, 

b) Review ofmethods for estimating 'missed dose' and 'un-moni~ored dose ' 

(for cases related to monitoring t~chnology and for cases where 

monitoring was not performed, monitoring data is not available or 

incomplete or otherwise inadequate), 

c) Review of the statistical approaches developed for multiple dose 

reconstructions, 

d) Review procedures used for determining whether data are sufficient to 

make a reasonable dose estimate, 

e) Review methods or procedures used for substituting exposure information 

for unavailable or incomplete information, 

f) Review methods for estimating uncertainty in dose and uncertainty 

distributions surrounding internal and external dose reconstructions on a 

facility and time specific basis and evaluate whether the benefit of the 

doubt was resolved in favor of the claimant where there were 

uncertainties. 

g) Review procedures and questionnaire used for work history phone 

interview.

h) Review the NIOSH methods, procedures and performance in evaluating, 

analyzing and validating all contractor work products 

2. Advanced Review 

The Advanced Review will include all task items in the Basic Review along with the 

additional tasks listed below: 

A. Review Data Gathering 

1. Review the entire analysis record to evaluate if relevant information exists which 

was not considered by NIOSH 

Note: The dose reconstruction report and all supporting documentation associated with a 

case, which was previously called the administrative record, is now called the NIOSH 

analysis record. 

2. Review the relevant aspects of the Site Profile as they apply to the individual case 

and evaluate the adequacy and completeness of the site profile and evaluate 

whether the information from the site profile is consistent with the information 

used for the individual dose estimate. 

3. Evaluate whether, to the extent practicable, all relevant sources of data (e.g., 

DOE, A WE, CDC, EML, NRC, EPA, External Health and Safety Regulators, 

GAO, DNFSB, Congressional Hearing Records, other research programs, 

research pubiications, publications regarding the history of the DOE complex, or 

administrative/court records) were identified, evaluated and where appropriate, 

included within the Site Profile database and where appropriate were used in the 

assessment of the individual dose reconstruction case. 

B. Review Work History Interview and Documentation provided by claimant 

1. Evaluate the phone interview in ascertaining relevant work history information. 

2. Evaluate whether, for the cases involving survivors, there has been an adequate 

effort to research co-located workers and other historical records to characterize 

the individual's work history. 

C. Review Internal and External Dose Estimates 

1. Evaluate whether the dose estimate is consistent with relevant radiological 

information within the NIOSH site profile (e.g. air monitoring, wipe data are 

consistent with bioassay results)

2. Compare case information and· asswnptions with relevant co-worker case 

information and asswnptions for consistency 

3. Blind Dose Reconstruction 

Using all raw data available to NIOSH the independent expert will develop an IREP dose 

input file that they feel is sufficient to make a determination with regard to POC. The 

case should be assembled in a manner consistent with NIOSH (i.e., all asswnptions 

should be stated, relevant procedures or technical basis docwnented, and relevant data 

used for the assessment highlighted within the analysis record). 

Period of Performance 

The timeframe for this task is six months. Interim reports to designated Board members and to 

the overall Board will be required at each Board meeting (approximately every 2 months). 

Reporting/Deliverable Requirements 

The contractor will be required to assemble Individual case review reports, Summary review 

reports (summarizing findings from an assigned group of cases), and assist the Board in 

developing reports for HHS. The format of these reports is detailed in the Board procedure on 

Processing Individual Dose Reconstruction Reviews. The Board will select groups of cases and 

designated Board members. This will include approximately 20 cases every 2 months (with 

proportions of types of cases consistent with those presented in the overview of this task).
