Program Evaluation Reports (PERs) and Program Evaluation Plans (PEPs)

NIOSH is committed to applying the best available science in dose reconstructions. In keeping with this commitment, completed cases with probabilities of causation less than 50% are reviewed as relevant new information becomes available. The results of these reviews are described in a Program Evaluation Report (PER). The PER details the effect, if any, of the new information on the completed dose reconstruction. If it appears that the compensability of a completed dose reconstruction may be effected, NIOSH is committed to working with the Department of Labor to reopen and rework the dose reconstruction, as appropriate. A Program Evaluation Plan (PEP) describes plans for evaluating specific program details or issues.

• PER 5: Misinterpreted Application of the External Dose Factor for Hanford Dose Reconstructions
  PDF 85 KB (6 pages)
  
  Document Number: OCAS-PER-0005 Rev-00
  
  About this Document: Describes the evaluation of the programmatic effect of the misinterpreted application of the bias factor for Hanford Dose Reconstructions.
  
  Approved: June 9, 2006
  
  Summary: An error in interpretation and application of the bias factor information in the Hanford External Dose Reconstruction Technical Basis Document (1) resulted in an underestimate of the external dose for certain Hanford claims. Claims that were potentially affected by this error were identified and those that had not already been submitted to the Department of Labor were returned to the ORAU team for rework. The cases that had been submitted to DOL were reevaluated by removing the bias factor, thus developing a revised external dose. The probability of causation for each of the affected claims was recalculated. This evaluation found that although this error appeared upon discovery to be rather significant, there was no impact on compensation decisions made by the Department of Labor.
  
  
• PER 29: Hanford TBD Revisions
  PDF 30 KB (4 pages)
  
  Document Number: OCAS-PER-0029 Rev-00
  
  About this Document: Document to determine which previously completed claims require evaluation for the effect of revising the Hanford TBD.
  
  Approved: December 18, 2007
  
  Summary: There were 1190 Hanford or PNNL claims completed prior to June 22, 2007, with a probability of Causation below 50%. The dose reconstruction methodology of each will be reviewed to determine if a new dose reconstruction is necessary to determine if the revisions increase the dose estimate. NIOSH will review these dose reconstructions to determine if they meet any of the criteria listed in the PER. NIOSH will provide DOL with the list of 1190 claims as well as a determination on each claim as to whether a new dose estimate is required. Documentation for each claim not requiring a new dose reconstruction will provide the basis for that determination.

Worker Outreach Activities

Based on a recommendation from the Advisory Board to provide workers and site experts with opportunities to participate in developing the technical documents used in dose reconstruction, NIOSH established a Worker Outreach Program.

At Worker Outreach Meetings, current and former DOE and AWE employees have opportunities to obtain information about Site Profiles, Technical Basis Documents, and Technical Information Bulletins, and to provide information for consideration and possible use in dose reconstruction. This process is valuable to ensure that the technical documents used in dose reconstruction contain correct and useful information.

Advisory Board Work Group on Hanford Site Profile

• Work Group Members
  
  This Work Group is responsible to review the Hanford site profile (as revised), to review the SEC petition(s) from Hanford petitioners, to review the NIOSH Evaluation Report of the petition, to review the SC&A Review of the Hanford Site Profile, to consider issues raised by the Board's contractor (SC&A) concerning the site profile and the petition Evaluation Report, and to assist NIOSH and SC&A in the resolution of such issues. The Work Group may recommend to the Board changes in the site profile as appropriate. The Work Group should also strive to develop recommendations to the Board on adding one or more classes to the SEC.

    About this Document: Establishes the technical basis for assignment of Hanford internal doses based on coworker bioassay data.
    
    Page Change Revision Includes: Approved page change revision. Revised to change thorium intakes based on assumption of equal "mass" as uranium; changed equilibrium conditions with progeny in the thorium chain based on new calculations and included statement of significance of Th-230 to be consistent with the current Hanford internal dosimetry TBD. Changes occurred on pages 33, 34, and 35. In Table 6-9 on page 35, in Section 6.7, corrected error in fission product intake in 1944-47 and adjusted I-131 intakes to be consistent with the Hanford Internal Dosimetry TBD. Made corrections to Table A-1 on page 38 in Attachment A. Incorporates internal and NIOSH formal review comments. The discussion and tables in Section 6.8 about radionuclides not measured in this study was removed. It is addressed in ORAUT-TKBS-0006-5. The pages affected by these changes are 23, 28, 30, and 32. This revision results in a reduction in assigned dose and no PER is required. No sections were deleted. Section 6.0: added Pu mixture statement consistent with Table in Section 5.1. Section 6.2: replaced sentence indicating all uranium exposure meant thorium exposure and referenced the Hanford internal dosimetry TBD for buildings and periods of thorium exposure. Clarified that thorium at PUREX would be Type M. In Table 6-4, corrected Type S intake for 1962-70 to 60.0 pCi/d; corrected PUREX type M intake to 0.957 based on type F. Added footnotes. Removed Table 6-5 on impurities in RU and referenced the TBD.

    Page Change Revision Includes: Corrects errors in units in Table 5-10 (page 27), Table 5-14 (page 28), Table 6-8 (page 33) and 6-10 (page 34). Corrects a value error in Table 6-9 (311.9 instead of 300 in the fifth column, page 33). Provides new guidance on how to assign radionuclides to unmonitored workers based on worker location, consistent with Hanford internal dosimetry TBD (Section 6.8, page 35). Corrects errors in Table 6-13 on page 36. No sections were deleted.
