            Cybersecurity Modernization Initiative
                We are taking steps to continue to modernize and secure our data, applications, and systems. We completed the first phase and restored many of the functions put on pause in May 2021. Now that the first phase is complete, work will resume at a slower pace but will speed up as new systems and applications are brought online. For more information and updates, please visit our Cybersecurity Modernization Initiative web page.

(Site Profile/Docket Number 023)
Location: Oak Ridge, Tennessee
Also known as: Clinton Laboratories
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 Oak Ridge National Laboratory (ORNL/X-10).
Class(es) Added to the SEC
All employees of the Department of Energy, its predecessor agencies, and their contractors and subcontractors who worked in any area at the Oak Ridge National Laboratory (X-10) in Oak Ridge, Tennessee, from June 17, 1943, through July 31, 1955, for a number of work days aggregating at least 250 work days, occurring either solely under this employment, or in combination with work days within the parameters established for one or more other classes of employees in the Special Exposure Cohort.
**Note:** This class was established by Petition 189.
Petitions Qualified for Evaluation
Below is a list of the petitions that qualified for evaluation. Select a petition on the list to view the table for that particular petition.
Petition 189 (Jan 1, 1943 to Dec 31, 1952)
	Petition 189
Steps in Petition Process:
Petition Details:Date Received
July 18, 2011Date Qualified for Evaluation
October 11, 2011Summary of Information in Petition
**Job Titles and/or Job Duties:** All contractor employees, subcontractor employees, and AEC employees who were monitored or should have been monitored for any of the various radionuclides and fission products present at the X–10 Plant
**Period of Employment:** January 1, 1943 through December 31, 1952
**Note:** The information above is what qualified for evaluation. During our evaluation of whether dose reconstructions can adequately be completed for the above job titles and period of employment, information may cause NIOSH to change some the dates or job titles/duties. Therefore, as this petition proceeds through the SEC petition process and if an SEC class is proposed, the proposed class may not exactly match the above information.Copy of the Petition Received

SEC Petitions Not Qualifying for Evaluation
There were six additional petitions received but did not qualify for evaluation. Five petitions did not meet the minimum petition requirements for evaluation and the other petition was withdrawn by the petitioner.
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.

                    March 29, 2018Pre-Decisional Document Policy
Please note that as part of the procedures and processes of the Advisory Board’s Work Groups, several kinds of pre-decisional documents may be developed. These pre-decisional documents, such as white papers, matrices, working drafts, etc., are distributed among Work Group members as research and background tools to facilitate discussion and deliberation. Although discussion during a public meeting may cover pre-decisional documents, these documents often are not further revised or finalized, and thus do not reflect the final determination or evaluation of the Advisory Board and its Work Groups. Additionally, some pre-decisional documents not otherwise posted on the website may contain sensitive information, which would require an interested party to obtain such documents by filing a Freedom of Information Act (FOIA) request with the CDC/ATSDR FOIA office at foiarequests@cdc.gov.
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.
