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 new information may result in an increase in dose for a completed dose reconstruction with a probability of causation of less than 50%, 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.
Program Evaluation Report: Evaluation of the Impact of Changes to the Isotopic Ratios in for the
Paducah Gaseous Diffusion Plant
PDF 23 KB (3 pages)
Document Number: OCAS-PER-0013 Rev-00
About this Document: This document provides a list of previously
completed claims that are potentially affected
by a revision to the Paducah isotopic ratios.
Approved: August 13, 2007
Summary: An initial selection of claims was based on the following search criteria:
1. Probability of Causation (POC) less than 50%
2. Dose Reconstructions completed prior to November 7, 2006.
These criteria were used to produce a list of 734 potentially affected claims. NIOSH will provide this list to DOL and request these claims be returned for a new dose reconstruction. The new dose reconstruction will be completed using all the current methodology which will account for any other changes affecting these claims.
Program Evaluation Plan: Evaluation of the Impact of Changes to the Isotopic Ratios in for the
Paducah Gaseous Diffusion Plant
PDF 20 KB (2 pages)
Document Number: OCAS-PEP-0013 Rev-00
About this Document: October 25, 2006, Revision 01 of ORAUT-TKBS-0019-5, Occupational Internal Dose was issued as part of the biennial review process. During the biennial revision of this TBD section, the information provided in existing document was evaluated to ensure that the published isotopic ratios for transuranic (TRU) radionuclides meet the criteria of providing either an accurate or maximum dose estimate. The results of the evaluation indicated that the current ratios did not meet that goal. Information provided in existing references (particularly PACE and the University of Utah, 2000; BJC, 2000), as well as that found in a new reference was assessed with the result that new TRU isotopic ratios were developed and are included in the TBD as Tables 5-2 and 5-2a in the revised document.
On November 7, 2006 Revision 01 of ORAUT-TKBS-0019-4, Occupational Environmental Dose was issued. A revaluation of the source data for ORAUT-TKBS-0019-5 led to a revision to the TRU isotopic ratios (relative to uranium) for estimating dose from these radionuclides. In addition, the authors have been able to categorize these ratios according to specific processes and periods as described below in conjunction with ORAUT-TKBS-0019-5.
Approved: March 21, 2007

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.
Below are the Worker Outreach Activities for the Paducah Gaseous Diffusion Plant:

Please note that as part of the procedures and processes of the Advisory Board's Work Groups, several kinds of pre-decisional documents may be developed. These documents, which can include white papers, matrices, working drafts, etc., are distributed among the Work Group members as research and background tools to facilitate discussion and deliberation. The discussions during the above meeting may cover a pre-decisional document. Because these types of documents are pre-decisional in nature, may contain sensitive information, and may change over time, they are not posted on our Web site. These finalized, reviewed and redacted pre-decisional documents are also available to other interested parties through an appropriate Freedom of Information Act request.
