Location: La Jolla, California

Also known as: Division of General Dynamics, GA, John Jay Hopkins Laboratory for Pure and Applied Science

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

There are currently no open/active SEC petitions from General Atomics.

Advisory Board Work Group on Uranium Refining Atomic Weapons Employers (AWEs)–formerly TBD 6001 Work Group

This Work Group reviews technical documents and Special Exposure Cohort (SEC) petitions for uranium refining AWEs assigned to it by the Advisory Board on Radiation and Worker Health. The Work Group makes recommendations to the Board on SEC petitions, reviews reports developed by the Board’s contractor (SC&A), and assists NIOSH and SC&A in resolving issues that arise through the review process.

Sites currently being considered by the Work Group include: General Atomics, Hooker Electrochemical, Reduction Pilot Plant, Westinghouse Electric Corp. (New Jersey), and W.R. Grace (Erwin, TN).

Meeting information (including agendas and transcripts) for this Work Group can be found on either the individual work site pages or on the Advisory Board and Public Meetings page.

  • David Pompa

Meeting Information:

  • No meetings have been scheduled to discuss this work site at this time.

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.

Site Profile

Note: The Site Profile below can be used to complete dose reconstructions for Area IV of the Santa Susana Field Laboratory, the Canoga Avenue Facility (Vanowen Building), the Downey Facility, and the General Atomics (these are sometimes referred to as Energy Technology Engineering Center [ETEC] or Atomics International).

Advisory Board and NIOSH Discussions on General Atomics

The General Atomics discussion papers listed below are working documents prepared by NIOSH or its contractor for use in discussions with the Advisory Board on Radiation and Worker Health or its Working Groups or Subcommittees. Draft, preliminary, interim, and white paper documents are not final NIOSH or Advisory Board (or their technical support and review contractors) positions unless specifically marked as such. These documents represent preliminary positions taken on technical issues prepared by NIOSH or its contractor.

The discussion papers have been reviewed to identify and redact any information that is protected by the Privacy Act 5 USC §552a and have been cleared for distribution.
