Medina Modification Center
(Site Profile/Docket Number 097)
Location: San Antonio, Texas
Also known as: Medina Facility
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.

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.

Program Evaluation Plans (PEPs) and Program Evaluation Reports (PERs)
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.

About this Document: New document to determine which previously completed claims require evaluation for the effect of issuing a revision to the Clarksville TBD.
Summary: Prior to November 4, 2006, there were 65 Clarksville and Medina claims completed which had a probability of causation below 50%. NIOSH will review these dose reconstructions to determine if the dose assigned in consistent or higher than the issued TBD. NIOSH will provide DOL with the list of 65 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.
