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.

Open/Active SEC Petitions

To date, there are no open/active SEC petitions from Bridgeport Brass Company.

SEC Petitions Not Qualifying for Evaluation

Two 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.

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.

    About this Document: Determines the effect of the revised Technical Basis Document for the Bridgeport Brass sites on previously completed claims.

    Summary: The resulting probability of causation (POC) was below 45% for 47 claims. The POC was greater than 50% for one claim. The remaining 2 claims resulted in a POC between 45% and 50%. For those two claims, IREP was run 30 times at 10,000 iterations per NIOSH procedures. The resulting POC was less than 50% for both claims. NIOSH will provide the Department of Labor with the list of all claims evaluated under this PER. Further, NIOSH will request the return of the one claim that would now result in a POC greater than 50%.
