Claimants must sign and return this form to NIOSH before the final dose reconstruction report can be sent to the Department of Labor for a compensation decision. The claimant has 60 days from the time he/she receives the form to sign and return it to NIOSH. Otherwise, NIOSH may administratively close the case. Signing this form does not mean that the claimant agrees or disagrees with the results of the dose reconstruction. It only confirms that the claimant does not have any more information to share with NIOSH at the time the form is signed. The OCAS-1 Form is titled, “Statement by the Claimant Closing the Record on a Dose Reconstruction Under the Energy Employees Occupational Illness Compensation Program Act.”
- Office of Compensation Analysis and Support (OCAS): former name of DCAS, Division of Compensation Analysis and Support, before it was changed from an office to a division. OCAS was previously part of the NIOSH Office of the Director (OD). The name change reflects the conversion from an Office to a NIOSH Division that reports to, but is not included within the NIOSH OD. This action is part of an ongoing project to reduce the size of the NIOSH OD, which is one of the goals of an OD Management Review begun in September of 2009. DCAS is primarily responsible for conducting occupational dose reconstructions under Subtitle B for cancer claims and for overseeing the petition process for adding more classes of employees under the Special Exposure Cohort (SEC).

- Records: records include all books, papers, maps, photographs, machine readable materials, or other documentary materials, regardless of physical form or characteristics, made or received by an agency of the US Government under Federal law or in connection with the transaction of public business and preserved or appropriate for preservation by that agency or its legitimate successor as evidence of the organization, functions, policies, decisions, procedures, operations or other activities of Government or because of the information value of the data in them (44 U.S.C. 3301External)
- Restricted Data (RD): defined by the Atomic Energy ActExternal as all data concerning the design, manufacture, or utilization of atomic weapons; production of special nuclear material (uranium and plutonium); use of special nuclear material in the production of energy. The Atomic Energy Act of 1954 recognized the need to make certain atomic energy information more accessible to the United States military. It provided for the transfer of information primarily dealing with the military utilization of atomic weapons from the RD category to another category of classified information. This category of information became known as “Formerly Restricted Data.” Although the word “formerly” implies the information may no longer be classified, it should be noted that Formerly Restricted Data remains classified. Documents containing RD are exempt from automatic declassification and must be reviewed by the Department of Energy prior to release.
- Secondary Cancer: a cancer that spreads from its origin to another area of the body.
- Secret: second-highest classification; if publicly disclosed, would cause “serious damage” to national security.
- Security Classification: the act or process by which information or matter is determined to require protection in the interest of national security under 42 U.S.C. 2162, Classification and Declassification of Restricted Data Cdc-pdf[169 KB (2 pages)]. There are 3 levels of security classification: Confidential, Secret, and Top Secret.
- Site Profile: a document that contains information about a facility’s general activities and radiation protection practices (i.e., frequency of badge exchange, types of radiation exposure monitored, medical exposure information). Site Profiles may be used by NIOSH when completing dose reconstructions to further understand or add to the personal exposure information for a particular claim; however, they are not always required to complete a dose reconstruction. Site Profiles are “living documents” and can be updated at any time as relevant information becomes available. If a Site Profile is revised at any time, previous non-compensable dose reconstructions will be reviewed to see if the revision affects the outcome of the claim. If it does affect the outcome, the dose reconstruction will be revised. More information on Site Profiles can be found on our FAQs: Technical Documents page.
- Site Research Database (SRDB): NIOSH database for research that contains site-specific data that can support the development of Technical Basis Documents, Site Profiles, Special Exposure Cohort petitions, and dose reconstructions.
- Special Exposure Cohort (SEC): a group of energy workers who do not need a dose reconstruction done for their claim because they meet specific criteria outlined in the Act/EEOICPA: a) have at least one of 22 specified cancers, b) worked at a facility covered under the Cohort, and c) worked for a specified amount of time. Workers may be added to the SEC if it is determined that 1) they were likely exposed to radiation at a nuclear facility, but it is not possible to estimate the amount of radiation the workers received with sufficient accuracy, and 2) there is a reasonable likelihood that the amount of radiation they received may have endangered their health. The Department of Labor determines whether an individual qualifies for compensation as part of the SEC. More information can be found on our Special Exposure Cohort (SEC) page.
- Special Exposure Cohort Petition Counselor: a specific individual at NIOSH responsible for providing advice to individuals interested in submitting an SEC petition. The SEC Counselor will assist petitioners in understanding the development, submission, qualification, evaluation, and the Board’s deliberation processes that their petition will undergo. If you are interested in filing an SEC petition or have questions about the petition process, contact the Counselor toll-free at 1-800-356-4674; directly at 513-533-6800; or email email@example.com.
- Technical Basis Documents (TBDs): the individual documents that form a Site Profile. An individual TBD contains information on a specific aspect of the work site. This aspect may be the physical layout of the work site, the work processes used, or other particular features of the work site and the work performed there. More information can be found on our Technical Documents Used in Dose Reconstruction and FAQs: Technical Documents pages.
- Technical Information Bulletins (TIBs): documents that contain information on specific technical issues or procedures for estimating radiation exposure. They are used to add to or supplement Technical Basis Documents and Site Profiles. TIBs may be used for a specific work site or multiple work sites. More information can be found on our Technical Documents Used in Dose Reconstruction and FAQs: Technical Documents pages.
- Top Secret: highest security level that if publicly disclosed, would cause exceptionally grave damage to the national security.
