(Site Profile/Docket Number 012)
Location: Aiken, South Carolina
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 Savannah River Site (SRS).
Class(es) Added to the SEC

SEC Petitions Not Qualifying for Evaluation
In addition to the petitions listed above, three petitions were received but did not qualify for evaluation because they did not meet the minimum petition requirements.
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. Worker Outreach Activities for the Savannah River Site (SRS):

This Work Group is responsible for reviewing the Savannah River Site (SRS) Site Profile, the SEC petition from Savannah River Site (SRS) petitioners, the NIOSH Evaluation Report of the petition, the SC&A Review of the Savannah River Site (SRS) Site Profile, considering issues raised by the Board’s contractor (SC&A) concerning the Site Profile and the petition Evaluation Report, and for assisting NIOSH and SC&A in the resolution of such issues. The Work Group may recommend to the Board, changes in the Site Profile as appropriate. The Work Group should strive to develop a recommendation to the Board on whether a class should be added to the SEC.

Transcript [1 MB (253 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.

Technical Basis Documents
Technical Basis Document for the Savannah River Site to be Used for EEOICPA Dose Reconstructions [4 MB (248 pages)]
**Revised:** April 5, 2005
**Revision Includes:** Adds Section 3.1.3 and Attachment C.3 to include ingestion of foodstuffs.
Occupational Medical Dose Section [581 KB (23 pages)]
**Revised:** November 30, 2009
**Revision Includes:** This revision is updated with newly acquired captured information. Includes Attributions and Annotations section. Specific changes are as follows: Added specific technique factors for PA and LAT projections for Type I machines and for LAT projections for Types II through IV machines in Table 3-3. Added Table 3-4. Rearranged the various sections and changed section headings: Section 3.3.1 changed from X-ray Apparatus to Photofluorography; Section 3.3.2 from Collimation to Radiography; Moved the existing section 3.4.2 on Collimation to Section 3.4. Added Section 3.3.3. Replaced the text in the existing Section 3.5 that contained example calculations of doses for the various projection types with two paragraphs of new text describing how doses were assigned. The original Table B.2 is now Table 3.9. All organ doses for the period 1950-1970 for Type I X-ray equipment have decreased; also doses for the male lungs and female bone marrow have been added. Entrance air kerma and skin doses for the PA and LAT projections have been deleted from Table 3-9. Table 3-10 and Table 3-11 have been added. The discussion regarding the four potential sources of uncertainty has been deleted except for the final statement to assume a +30% uncertainty at the 99% confidence level as stated in OTIB- 0006. Changed reported range on technique factors for the Picker machine. Values added to Table 3-3; The calculated entrance and exit skin doses were compared to the measured entrance and exit skin doses of Cooley (Cooley, 1967) made on the mobile Picker machine for the PA chest for the 1950-1970 time period. The comparison is shown in Table 3-7. The 21% uncertainty derived from the Cooley measurements is substituted into the root mean square calculation for combined uncertainty instead of the 10% value initially reported from this source of uncertainty in ORAUT-OTIB 0006 (2005). As a result of this substitution, the resulting combined, standard uncertainty is 34%, and rounded up to 35%. Skin doses were put into a different table format to more closely match the skin dose tools. Incorporates formal internal and NIOSH review comments. Constitutes a total rewrite of the document.Technical Information Bulletins (TIBs)
ORAUT-OTIB-0081, Rev. 5: Internal Coworker Dosimetry Data for the Savannah River Site (SRS) [6.9 MB (287 pages)]
**Revised:** September 1, 2020
**Revision Includes:** Adds the intake rates for type SS plutonium, uses the ORAUT-RPRT-0096 multiple imputation method for americium bioassay data, updates americium and thorium intake rates, and references ORAUT-RPRT-0070 for thorium intake rates. Incorporates formal internal and NIOSH review comments. Constitutes a total rewrite of the document.
**About this Document:** Provides internal coworker data for the Savannah River Site.
**Note:** The title of this document was changed from “Internal Coworker Dosimetry Data for the Savannah River Site (SRS)” to “Internal Dosimetry Co-Exposure Data for the Savannah River Site” on September 1, 2020, to accurately describe the coworker model as a co-exposure model. Previous versions of this document are located on this page under the Document Archive for Technical Information Bulletins (TIBs) section.
ORAUT-OTIB-0032 Rev-00 PC-1: External Coworker Dosimetry Data for the Savannah River Site [137 KB (10 pages)]
**Page Change Revision:** November 7, 2006
**Page Change Revision Includes:** Page change revision due to release of ORAUT-OTIB- 0052 Rev 00. Updates required language on page 4 in Section 1.0. References ORAUT-OTIB-0052 Rev 00 on page 6 in Section 5.0. Completes Section 8.0 on page 8. Revises title of Table 3 on page 10. No changes occurred as a result of formal internal review. This revision results in an increase in assigned dose and a PER is required.
**About this Document:** Provides information to allow Dose Reconstructors (Health Physicists) to assign doses to Savannah River Site workers who have no or limited monitoring data, based on site coworker data.
OCAS-TIB-006 Rev-02: Interpretation of External Dosimetry Records at the Savannah River Site (SRS) [17 KB (3 pages)]
**Revised:** October 4, 2007
**Revision Includes:** Clarification of applicability per SC&A comments. This revision replaces guidance found in the SRS Site Profile dated April 5, 2005.
**About this Document:** Provides guidance on the Interpretation of External Dosimetry Records at the Savannah River Site.
**ORAUT-OTIB-0001 Rev-00: Maximum Internal Dose Estimates for Savannah River Site (SRS) Claims — CANCELED**
**Approved:** July 15, 2003
**About this Document:** Describes the maximum internal dose estimates for Savannah River Site (SRS) claims.
**Note:** This document has been canceled. Site-specific hypothetical intakes are no longer assigned. ORAUT-OTIB-0018, “Internal Dose Overestimates for Facilities with Air Sampling Programs”, or co-exposure values when available, will be used in its place. Previous versions of this document are located on this page under the Document Archive for Savannah River Site (SRS) section.
OCAS-TIB-007 Rev-01: Neutron Exposures at the Savannah River Site [35 KB (6 pages)]
**Revised:** October 15, 2007

            March 21, 2005Program 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.
OCAS-PER-0001 Rev-00: Misinterpreted Dosimetry Records Resulting in an Underestimate of Missed Dose in Savannah River Site Dose Reconstructions [958 KB (4 pages)]
            September 8, 2003
**About this Document:** Describes the evaluation of the programmatic effect of the misinterpreted dosimetry records resulting in an underestimate of the missed dose for Savannah River Site dose reconstructions.
**Summary:** While the underestimated missed dose resulted in a non-claimant favorable estimate of missed dose, the overestimated onsite ambient dose offset this underestimate. As a result, no further evaluation is necessary because the offset still resulted in a slight claimant favorable bias in the dose estimate and resulting probability of causation.
OCAS-PER-0002 Rev-00: Error in Surrogate Organ Assignment Resulting in an Underestimate of X-ray Dose in Savannah River Site Dose Reconstructions [482 KB (4 pages)]
            December 15, 2003
**About this Document:** Describes the evaluation of the programmatic effect of an error in surrogate organ assignment resulting in a potential underestimate of the X-ray dose for certain Savannah River Site dose reconstructions.
**Summary:** An error in surrogate organ assignment for the liver, gall bladder and spleen (ovaries was assigned instead of lung) resulted in the underestimation of X-ray organ doses in three completed dose reconstructions. The impact on the probability of causation in these three cases has been evaluated and found to be minimal (<0.5%), and the probable compensability status of these claims was unaffected. No revision of any completed dose reconstructions is warranted; however, to preclude future occurrences of this error, revisions of several Technical Basis Documents has been initiated.
OCAS-PER-0019 Rev-00: Program Evaluation Report: The Effect of Additional Neutron Dose Data from the Savannah River Site [20 KB (2 pages)]
            May 18, 2007
**About this Document:** New document to report the impact of additional neutron dose data received from the Savannah River Site.
**Summary:** Dosimetry records are requested from the Savannah River Site for each claim received from the Department of Labor with Savannah River employment. This data is used in reconstructing the individuals’ radiation dose. The Savannah River site notified NIOSH that additional data pertaining to neutron dosimetry was not sent for several claims. The additional data has since been received and added to the original dosimetry data. Previously completed claims were re-evaluated to determine the affect of this new data on the individual claims. This Program Evaluation Report (PER) was prepared to report the results of that evaluation.
OCAS-PER-0030 Rev-00: Program Evaluation Report: Savannah River Site TBD Revisions [31 KB (3 pages)]
            December 18, 2007
**About this Document:** Document to determine which previously completed claims require evaluation for the effect of revising the Savannah River Site< TBD.
**Summary:** There were 54 Savannah River Site claims completed prior to August 21, 2003, (issue date of revision 1) with a probability of Causation below 50%. The dose reconstruction methodology of each will be reviewed to determine if a new dose reconstruction is necessary to determine if the revisions increase the dose estimate. NIOSH will review these dose reconstructions to determine if they meet any of the criteria listed in this PER. NIOSH will provide DOL with the list of 54 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.Public Comments on Savannah River Site (SRS) Documents
