Neton, Associate Director for Science FOR DOCUMENTS MARKED AS A TOTAL REWRITE, REVISION, OR PAGE CHANGE, REPLACE THE PRIOR REVISION AND DISCARD / DESTROY ALL COPIES OF THE PRIOR REVISION. New Total Rewrite Revision Page Change Document No. ORAUT-TKBS-0052 Revision No. 01 Effective Date: 07/11/2016 Page 2 of 33 PUBLICATION RECORD EFFECTIVE REVISION DATE NUMBER DESCRIPTION 08/30/2006 00 New document to describe the Pacific Proving Ground and other oceanic test locations to enable the preparation of dose reconstructions. First approved issue of Revision 00. Incorporates internal and NIOSH formal review comments. There is no change to the assigned dose and no PER is required. Training required: As determined by the Task Manager. Initiated by Lori J. Arent. 07/11/2016 01 Revision initiated to update occupational medical and external dose information. Added excerpts to Section 1.3 from EEOICPA Bulletin No. 06-15 and EEOICPA Bulletin No. 07-05 clarifying that 83 days of continuous presence on land or ships would be equivalent to the 250-workday requirement for eligibility for compensation. Removed reference in Section 3.0 to ORAUT-PROC-0061 and added evaluation requirements under ORAUT-OTIB-0079. Provided additional information about the assignment of X-ray procedures based on various DOE responses. Revised Section 6.0 requirement to assign 95th-percentile doses from Attachment A for unmonitored workers and added requirement to Attachment A for comparison and assignment of the larger of missed plus recorded dose to the 95th-percentile doses. Removed requirement to assume beta-to- gamma ratios from the Nevada Test Site profile. Added Section 6.1 to provide beta-to-gamma ratios as a function of time after detonation and distance from source plane, which is favorable to claimants. Added Section 6.2 to provide methods for reconstructing dose from fallout from the GREENHOUSE operation for workers on contaminated islands and ships. Added Sections 6.3.1 and 6.3.2 to provide methods for determining penetrating and nonpenetrating dose. Added Section 6.3.3 for determining penetrating and nonpenetrating dose from fallout. Revised Section 7.0 to include all dose reconstruction methods. Incorporates formal internal and NIOSH review comments. Constitutes a total rewrite of the document. Training required: As determined by the Task Manager. Initiated by Eugene M. Rollins.
