    this document in PDF PDF 113 KB (9 pages)

    Revision Includes: Revised as a result of a biennial review. Updated cover page. Added required standard language to the Purpose section. Added references to the Reference section. Constitutes a total rewrite of document. Incorporates internal and DOL formal review comments. This revision results in no change to the assigned dose and no PER is required.

  2. Site Description
    (Revised October 4, 2006)
    this document in PDF PDF 470 KB (38 pages)

    Revision Includes: Revision initiated for biennial review and to incorporate recent direction from NIOSH to include DOL review comments. Revised to change from a page change (Rev 00 PC-1-A) to a revision (Rev 01- A) as a result of worker outreach comments from PACE Local 5-689 and SPFPA Local 66 04/16/2004 meeting. Approved issue of Revision 01. Section 2.3.12 was added to reflect new information on building X-770 facilities. Table 2-15 was also added. Three references were added. Added a Purpose and Scope subsection to the Introduction (Section 2.0). Three references were added. No sections were deleted. No further changes occurred as a result of internal formal review. Incorporates NIOSH formal review comments. This revision results in no change to the assigned dose.


  3. Occupational Medical Dose
    (Revised April 8, 2013)
    this document in PDF PDF 228 KB (19 pages)

    Revision Includes: Addresses Sanford Cohen & Associates concerns about the document as identified in SC&A-TR-TASK1-0020, Review of the NIOSH Site Profile for the Portsmouth Gaseous Diffusion Plant (see Section 3.3.1). Adds skin doses for all applicable projections and exposure periods. Updates information to conform with revised ORAUT-OTIB-0006, Dose Reconstruction from Occupational Medical X-Ray Procedures. Updates references and added Attributions and Annotations section. Revises information on exposure periods based on recent issuance of ORAUT-OTIB-0079, Guidance on Assigning Occupational X-Ray Dose Under EEOICPA for X-Rays Administered Off Site. Updates pre-1982 X-ray doses, added lumbar spine doses, and added new period for 2010 present based on new information. Incorporates formal internal and NIOSH review comments. Constitutes a total rewrite of the document.

  4. Occupational Environmental Dose
    (Revised August 24, 2009)
    this document in PDF PDF 287 KB (26 pages)

    Revision Includes: Changes were made to the document as per OCAS comments. The Uranium daughter intake values were corrected in Table 4-2. Footnote f was added: "Uranium progeny intakes calculated from recorded or estimated equilibrium fractions with the Uranium parent radionuclides." Changed the term, "claimant favorable" to "favorable to claimant(s)" as appropriate throughout the document. Incorporates formal internal and NIOSH review comments, such as revising wording of footnote "e" in Table 4-2. Equation 4-1 for the geometric standard deviation (GSD) has been deleted along with citations to the GSD in the text and in Table 4-2. This follows ORAUT-PROC-0031 guidance. Deleted Table 4-7 due to the data being limited and not adding value. Revised Section 4.2.3 to provide a better description of the calculations.

  5. Occupational Internal Dose
    (Approved November 24, 2004)
    this document in PDF PDF 316 KB (27 pages)


  6. Occupational External Dose
    (Page Change Revision August 20, 2007)
    this document in PDF PDF 881 KB (59 pages)

    Page Change Revision Includes: Approved page change initiated to clarify information provided in Section 6.3.2.2.1 on page 20 and the application of neutron dose. The need for a PER as stated in Rev. 01 of this TBD is not correct. No PER is required since the method of assigning unmonitored neutron dose remained the same through the previous TBD revisions (i.e. the application of a neutron to photon ratio of 0.2, see Section 6.3.4.2.4). Added NIOSH date reference in Section 6.7 on page 47. Added an Attributions and Annotations section in Section 6.8 on page 48. No further changes occurred as a result of formal internal and NIOSH formal review.

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.

At the current time, no PERs or PEPs specific to Portsmouth Gaseous Diffusion Plant have been developed. However, we have developed PERs and PEPs that pertain to multiple sites. To view all PERs and PEPs that have been developed, please refer to the Program Evaluation Reports (PERs) and Program Evaluation Plans (PEPs) page.

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 Portsmouth 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.
