(Site Profile/Docket Number 029)
Location: Mercury, Nevada
Special Exposure Cohort Petition Information for NTS
The Special Exposure Cohort (SEC) is a unique category of employees established by the Act (42 CFR Part 83). Claims compensated under the SEC do not have to go through the dose reconstruction process. To qualify for compensation under the SEC, a covered employee must meet specific requirements (e.g., must have at least one of 22 “specified cancers,” and have worked for a specified time period at one of the SEC sites). Classes of employees and work sites can be considered for addition to the SEC through a NIOSH petition process. More information about the Special Exposure Cohort can be found on our Frequently Asked Questions page.
Open/Active SEC Petitions
To date, there are no open/active SEC petitions from the Nevada Test Site.
Classes Added to the SEC
Department of Energy (DOE) employees or DOE contractor or subcontractor employees who worked at the Nevada Test Site from January 27, 1951 through December 31, 1962 for a number of work days aggregating at least 250 work days, either solely under this employment or in combination with work days within the parameters (excluding aggregate work day requirements) established for other classes of employees included in the SEC, and who were monitored or should have been monitored.
**Note:** This class was established from Petition 55
All employees of the Department of Energy, its predecessor agencies, and its contractors and subcontractors who worked at the Nevada Test Site, from January 1, 1963 through December 31, 1992, for a number of work days aggregating at least 250 work days, occurring either solely under this employment or in combination with work days within the parameters established for one or more other classes of employees in the SEC

SEC Petitions Not Qualifying for Evaluation
In addition to the petitions listed above, nine petitions were received but did not qualify for evaluation because they did not meet the minimum petition requirements.
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:

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. In January, 2008, the Board tasked the Work Group with reviewing the petition from NTS for adding a class to the SEC. The Work Group is responsible for reviewing the NIOSH Evaluation Report (ER), the SC&A review of the ER, reviewing the SC&A Site Profile Review, and for tracking the resolution process for SC&A findings and NIOSH responses. The Work Group may recommend to the Board, changes in the site profile as appropriate. The Work Group should strive to develop a recommendation to the Board on whether a class should be added to the SEC.

Transcript [1.5 MB (381 pages)]Pre-Decisional Document Policy
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 pre-decisional documents, such as white papers, matrices, working drafts, etc., are distributed among Work Group members as research and background tools to facilitate discussion and deliberation. Although discussion during a public meeting may cover pre-decisional documents, these documents often are not further revised or finalized, and thus do not reflect the final determination or evaluation of the Advisory Board and its Work Groups. Additionally, some pre-decisional documents not otherwise posted on the website may contain sensitive information, which would require an interested party to obtain such documents by filing a Freedom of Information Act (FOIA) request with the CDC/ATSDR FOIA office at foiarequests@cdc.gov.
Technical Documents
If the energy employee’s personal radiation information is incomplete, NIOSH will use other sources to estimate the radiation dose. This may involve using technical documents called Site Profiles, Technical Basis Documents, and Technical Information Bulletins.

Occupational Environmental Dose [1.9 MB (94 pages)]
            Revised February 19, 2020
**Revision Includes:** Clarified in Section 4.3.1 that site maximum values would be entered into IREP as constants. Clarified in Section 4.4.4 that 220Rn should be assumed to be present at twice the concentrations of 222Rn in Table 4-20. Added discussion in Sections 4.3.1 to provide maximum and best-estimate methods, respectively, for estimating onsite ambient external doses. In Section 4.5.2, clarified that the intake values in Tables 4-7 and 4-11 are to be considered bounding and should be applied in IREP as constants. Also for a best estimate, 10% of the intakes in Tables 4-7 and 4-11 should be assigned. The best-estimate intakes should be applied in IREP as a lognormal distribution with a GSD of 3.0. Added to Section 4.4.4 that doses for all organs should be adjusted in accordance with DCAS-TIB-011 for radon (DCAS 2018). Added instructions in Section 4.4.4 for the application of underground occupancy factors for work in the gravel gerties and tunnels. Incorporates formal internal and NIOSH review comments. Constitutes a total rewrite of the document.
Occupational Internal Dose [963 KB (116 pages)]
            Revised August 17, 2012
**Revision Includes:** Added SEC language. Added dates to Table 5-1 for C-720 Maintenance. Clarified column titles in Tables 5-2 and 5-2a. Updated references. Deleted previous Table 5-3 (not used in dose reconstruction). Revised Table numbers. Revised in vitro measurement in Table 5-3 for 1952 – 1988 period from 5 μg/L to 0.005 mg/L. Moved reporting formats and codes to Attachment A. Added Attachment B, Internal Dosimetry Coworker Data for PGDP (formerly ORAUT-OTIB-0037 Rev 00). Added the option for dose reconstructors to use the 95th-percentile intake rate in Attachment B. Added Attachment C to provide dose reconstructors a general idea of the types of job categories, work activities, and work locations for which internal dose assignment might be necessary. Added Section 5.4.5, Assessment of Intake for Unmonitored Employees. Moved Table 5-8, A History of Significant Events, to Attachment C. Incorporates formal NIOSH review comments.

**Revision Includes:** Fixes Table 6-1 for neutron dosimeters (1961–1979, 1979–1986, and 1987–2000) that included a factor of 2 (for claimant favorability) based on the discussion in Sections 6.3.4.2.1, 6.3.4.2.2, and 6.3.4.2.3. This multiplier has been removed and the language in these sections modified. Section 6.3.1.4 – Language was added to clarify REECo reporting practices for workers visiting the site and to document the correct source of information when evaluating REECo employees assigned to TTR. Clarification of the beta-to-gamma ratio to be applied before 1966 during most dose reconstructions. Language was added to Section 6.4.2.1 to direct the reader to Attachment C if a more accurate estimate of the beta to gamma ratio was required. Section 6.4.2.2 was moved to Attachment C, Section C.2, and Section 6.4.2.3 was moved to Attachment C, Section C. 3. In Section 6.5.2 the beta-to-gamma ratio to be used before 1966 was clarified. Uncertainty paragraph was deleted because for beta dose OTIB-ORAUT-0017 is the methodology used. Section 6.5.1 – Language added about unmonitored workers and when no external monitoring indicated a worker was not on NTS. Incorporates formal internal and NIOSH review comments. Constitutes a total rewrite of the document.Top of Page

            December 13, 2005Program 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.
PER 32: Nevada Test Site TBD Revisions [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.Public Comments on Nevada Test Site Documents

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.
