    Page Change Revision Includes: Approved page change revision to add information to NTS area descriptions on pages 14, 15, 17, and 25 in Sections 2.2.2, 2.2.3, 2.2.4, 2.2.6, and 2.2.25. Added references on pages 52, 53, 54, and 55. Updated references on pages 27, 32, and 51 in Sections 2.2.31, 2.3.1, and 2.4. Changes were made to Table A-2 on page 63 in Attachment A. Added acronyms on pages 7 and 8. Revised legal language on pages 10 and 11 in Section 2.1. Information was added to Attachment B on page 65 and Attachment C on pages 79 and 80. Changes were made to Table C-1 on pages 81, 82, 83, and 84. Incorporates formal internal and NIOSH review comments.

  3. Occupational Medical Dose
    (Revised June 22, 2007)
    this document in PDF PDF 122 KB (29 pages)

    Revision Includes: Initiated to concur with ORAUT-OTIB-0006 (ORAUT 2005), current data in other TBDs, and to include new legal wording in Section 3.1. Constitutes a total rewrite of the document. Incorporates formal internal and NIOSH review comments. Adds Attributions and Annotations section. This revision results in no change to the assigned dose and no PER is required.

  4. Occupational Environmental Dose
    (Revised May 27, 2008)
    this document in PDF PDF 525 KB (77 pages)

    Revision Includes: Approved revision initiated to apply only to post 1962 employment periods and all covered employees including those identified by job classification as a drillback operator prior to 1965. Also applies to covered employees involved with any of the 10 underground tests that resulted in unexpected release of radioactive materials. Revised Table 4.2.1.2.2.-2 (new Table 4-3) to reflect 2,000 hr/yr and 2400 m3/yr breathing rate. Deleted Tables 4.2.1.2.2-3 and 4.2.1.2.2-4. Deleted Sections 4.2.1.2.3 and 4.2.1.2.4. Added Sections 4.2.1.2.3 and 4.1.2.4 to introduce revised method for assigning environmental ambient inhalation intakes. Replaced Section 4.2.2 with ambient ingestion intake section. Revised Section 4.4 to include dose from radon and other alpha and beta emitting radionuclides and to include discussion of radon exposure in Gravel Gerties. Added Section 4.4.3. Revised Section 4.4.4, Table 4.21 to increase radon WLM for G-Tunnel prior to 1984 and to maximize radon exposures for unidentified work locations. Added discussion of radon in Gravel Gerties. Added Section 4.4.5 to provide method for assigning inhalation and ingestion intakes for underground workers. Added Section 4.5.2 to provide instructions to dose reconstructors for assigning inhalation and ingestion ambient environmental intakes for all workers at the NTS. Occupational environmental dose will increase for all claims not previously worked using ORAUT-OTIB-0018 or ORAUT-OTIB-0002. Also, cases of lung, ET1, and ET2 will need to be re-evaluated for increased radon exposures. Attachments A and B (formerly Rollins 2007, SRDB Ref ID: 37805) were added to support the changes discussed in Section A.6.0 which included enriching the near-field environment with refractory elements. The 01-C version only added refractory elements back to the depleted refractory near-field environment given by the Hicks data (i.e., multiplied the Hicks refractory values by 2). The 01-D version enriched the near-field refractory environment by multiplying the Hicks refractory values by 4. Assumption of the enriched refractory near-field environment resulted in larger fission and activation product inhalation and ingestion correction factors (Tables 4-8 and 4-12) and increased number of affected organs and the resultant doses (Tables 4-9 and 4-14). Incorporates formal internal and NIOSH review comments. Constitutes a total rewrite of the document.

  5. Occupational Internal Dose
    (Revised May 28, 2008)
    this document in PDF PDF 583 KB (112 pages)

    Revision Includes: Approved Revision 01 to incorporate additional information regarding bioassay procedures used and expanded MDAs. Addresses comments from the Advisory Board's contractor, and includes guidance to the dose reconstructor in Section 5.6. Adds Attributions and Annotations Section 5.7. Incorporates formal internal and NIOSH review comments. Adds Sections 5.6.4 and 5.6.5. Updates boilerplate language in Section 5-1 and adds reference to OCAS-IG- 003. Constitutes a total rewrite of the document.

  6. Occupational External Dose
    (Page Change Revision May 28, 2008)
    this document in PDF PDF 1.7 MB (125 pages)

    Page Change Revision Includes: Approved page change revision to incorporate expanded co-worker data on pages 45 - 47, 49, and 50 in Section 6.4. Text was added to Section 6.5.1 (page 57) and Section 6.5.2 (page 58) to address hot particle issues and the use of the document Hazards to Personnel Reentering the Nevada Test Site Following Nuclear Reactor Tests. Changes to attributions and annotations numbering were made on pages 59-61, 67, 68, 92, and 95. No sections were deleted. Made additional changes to correct the wording in Section 6.5.1 on page 57 to be consistent with the information in Section 6.3.5.1 on page 36 regarding the lead covering on the dosimetry and identification of the25% as a dose correction factor between the years 1960 and 1965. Corrected the dates in Section 6.3.5.1 on page 36 to be consistent with the dates in Table 6-1. Added information for Operations BREN and HENRE and the Super Kukla reactor. As a result of NIOSH formal review the following pages were changed: 9, 12, 13, 17-19, 21, 24 - 34, 36, 37, 39 - 42, 44 - 47, 49 - 66, 68, 71 - 78, 93 - 95, 101, 102, 104, 105, and 110. These changes occurred in the Acronyms and Abbreviations Section, Sections 6.1, 6.3, 6.4, 6.5, 6.6, Reference Section, Glossary Section and Attachment A.

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 32: Nevada Test Site TBD Revisions
    this document in PDF PDF 17 KB (2 pages)

    Document Number: OCAS-PER-0032 Rev-00

    About this Document: Document to determine which previously completed claims require evaluation for the effect of revising the Nevada Test Site TBD.

    Approved: December 18, 2007

    Summary: There were 481 Nevada Test Site claims completed prior to July 30, 2007, (issue date of revision 1) with a probability of Causation below 50% that meet the criteria above. 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 this PER. NIOSH will provide DOL with the list of 481 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.

Below are the Worker Outreach Activities for the Nevada Test Site:

Advisory Board Work Group on Nevada Test Site, Site Profile


The Nevada Test Site (NTS) Site Profile Work Group was formed in the Spring of 2006. The Work Group was formed to review the NTS Site Profile document for accuracy and authenticity. The Work Group is also responsible for reviewing the SC&A Site Profile Review and for tracking the resolution process for SC&A findings and NIOSH responses. The Work Group is responsible for developing appropriate recommendations to the Board relating to the Site Profile. In January, 2008, the Board also tasked the Work Group with reviewing the petition from NTS for adding a class to the Special Exposure Cohort. The Work Group is responsible to review the NIOSH Evaluation Report (ER) as well as the SC&A review of the ER, to assist in resolving differences, and for making appropriate recommendations to the Board.
