Special Exposure Cohort Petition Information

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.

    Document Number: ORAUT-TKBS-0053 Rev-02

    Revised: January 13, 2021

    Revision Includes: Revision initiated to update the document with new information related to a revision of ORAUT-OTIB-0006, Dose Reconstruction from Occupational Medical X-Ray Procedures, and the implementation of ORAUT-OTIB-0088, External Dose Reconstruction. Included information for skin doses to various areas from posterior-anterior and lateral chest X-rays in Table 3-5, and from lumbar spine examinations in Table 3-7. X-ray doses and computational information in Tables 3-1, 3-2, and 3-4, which had previously been labeled “Pre-1970” were renamed to include the year 1970. Information and doses in the tables previously labeled “1970–1985” were changed to reflect the period “1971–1975.” Skin dose information in Table 3-4 for 1986 to present were changed to reflect the revision of the backscatter factor from ORAUT-OTIB-0006. Revision updated to upgrade the document with new and corrected environmental data, both internal and external. Previously unavailable reference documents from Lawrence Livermore National Laboratory were employed to reevaluate existing environmental data and to provide additional data for the period 2004 to 2018. Updated uncertainty information regarding medical dose with information from the International Vocabulary of Metrology (JCGM 2008). Included information and corrections regarding NTA film badges. Incorporates formal internal and NIOSH review comments. Constitutes a total rewrite of the document.

      Document Number: ORAUT-TKBS-0053 Rev-01

      Revision Includes: Updates the document with new information. Modifies Sections 1.0, 5.0, and 6.0 to incorporate the Special Exposure Cohort class through 1994, including references to SEC-ER and HHS designation letter. Replaces reference to ORAUT-TKBS-0048, Site Profile for the Brookhaven National Laboratory, with ORAUT-TKBS-0036-6, Argonne National Laboratory-East – External Dosimetry. Adds information pertaining to chronic lymphocytic leukemia to Section 3.3 and added Table 3-6. Amends Section 5.2 to eliminate the sentence that only tritium and uranium were of concern, and stating there were limited bioassay data for tritium and uranium. Changes Section 5.7 to reflect that unmonitored internal dose is only applicable post-SEC, to indicate applicable years based on facility decommissioning, to remove all references to maximum permissible concentrations, and to supply uranium intake information for all solubilities. Altered Table 5-5 to remove the row related to 1959 and to change the “1990s” row to “post-1994.” Adjusts Table 5-8 for consistency with Table 5-2, to account for tritium intake through skin absorption, and to address uranium tritides, adding ORAUT-OTIB-0066 as a reference. Includes an instruction for dose reconstructors to use minimum detectable activities as provided in the records when available. Incorporates formal internal and NIOSH review comments.
