            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 022)
Location: Piketon, Ohio
Also known as: PORTS
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 Portsmouth Gaseous Diffusion Plant.
Class(es) Added to the SEC
**Gaseous Diffusion Plants** – Employees who worked at least 250 days before February 1, 1992, at a gaseous diffusion plant in Paducah, Kentucky; Portsmouth, Ohio; or Oak Ridge, Tennessee and who were or could have been monitored in those jobs using dosimetry badges
**Note:** The SEC was established by The Act. The Portsmouth Gaseous Diffusion Plant was one of the classes that Congress included when The Act was signed.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.

Transcript [700 KB (272 pages)]Pre-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.
Site Profile
Introduction [68 KB (9 pages)]
            Revised February 12, 2007
**Revision Includes:** Revised as a result of a biennial review. Updated cover page. Added required standard language to the Purpose section. Added references to the Reference section. Constitutes a total rewrite of document. Incorporates internal and DOL formal review comments. This revision results in no change to the assigned dose and no PER is required.
Site Description [352 KB (38 pages)]
            Revised October 4, 2006
**Revision Includes:** Revision initiated for biennial review and to incorporate recent direction from NIOSH to include DOL review comments. Revised to change from a page change (Rev 00 PC-1-A) to a revision (Rev 01- A) as a result of worker outreach comments from PACE Local 5-689 and SPFPA Local 66 04/16/2004 meeting. Approved issue of Revision 01. Section 2.3.12 was added to reflect new information on building X-770 facilities. Table 2-15 was also added. Three references were added. Added a Purpose and Scope subsection to the Introduction (Section 2.0). Three references were added. No sections were deleted. No further changes occurred as a result of internal formal review. Incorporates NIOSH formal review comments. This revision results in no change to the assigned dose.
Occupational Medical Dose [228 KB (19 pages)]
            Revised April 8, 2013
**Revision Includes:** Addresses Sanford Cohen & Associates concerns about the document as identified in SC&A-TR-TASK1-0020, Review of the NIOSH Site Profile for the Portsmouth Gaseous Diffusion Plant (see Section 3.3.1). Adds skin doses for all applicable projections and exposure periods. Updates information to conform with revised ORAUT-OTIB-0006, Dose Reconstruction from Occupational Medical X-Ray Procedures. Updates references and added Attributions and Annotations section. Revises information on exposure periods based on recent issuance of ORAUT-OTIB-0079, Guidance on Assigning Occupational X-Ray Dose Under EEOICPA for X-Rays Administered Off Site. Updates pre-1982 X-ray doses, added lumbar spine doses, and added new period for 2010 – present based on new information. Incorporates formal internal and NIOSH review comments. Constitutes a total rewrite of the document.
Occupational Environmental Dose [287 KB (26 pages)]
            Revised August 24, 2009
**Revision Includes:** Changes were made to the document as per OCAS comments. The Uranium daughter intake values were corrected in Table 4-2. Footnote f was added: “Uranium progeny intakes calculated from recorded or estimated equilibrium fractions with the Uranium parent radionuclides.” Changed the term, “claimant favorable” to “favorable to claimant(s)” as appropriate throughout the document. Incorporates formal internal and NIOSH review comments, such as revising wording of footnote “e” in Table 4-2. Equation 4-1 for the geometric standard deviation (GSD) has been deleted along with citations to the GSD in the text and in Table 4-2. This follows ORAUT-PROC-0031 guidance. Deleted Table 4-7 due to the data being limited and not adding value. Revised Section 4.2.3 to provide a better description of the calculations.
Occupational Internal Dose [318 KB (26 pages)]
        November 24, 2004
Occupational External Dose [881 KB (59 pages)]
            Page Change Revision August 20, 2007
**Revision Includes:** Approved page change initiated to clarify information provided in Section 6.3.2.2.1 on page 20 and the application of neutron dose. The need for a PER as stated in Rev. 01 of this TBD is not correct. No PER is required since the method of assigning unmonitored neutron dose remained the same through the previous TBD revisions (i.e. the application of a neutron to photon ratio of 0.2, see Section 6.3.4.2.4). Added NIOSH date reference in Section 6.7 on page 47. Added an Attributions and Annotations section in Section 6.8 on page 48. No further changes occurred as a result of formal internal and NIOSH formal review.
