Neton, Associate Director for Science 12/18/2009 01 Approved revision to add LAT chest doses for all periods, skin doses for various parts of the body, and an explanation of terminology. Sections 3.0 and 3.1 were modified as a result of these changes. Tables 3-1 through 3-6 were modified and Tables 3-7 and 3-8 were added. The definition of occupational medical dose was revised and three reference titles were changed. Wording in Section 6.2.1 about external uranium dose was modified. Revision made to add unmonitored doses prior to 1953. Section 6.2.1 reworded to remove OTIB-0004 discussion and add new methodology. Section 6.3.1 was modified to include two eras of unmonitored doses. Figure 6-2 was altered to reflect the new unmonitored dose methodology for doses prior to 1953. Table 5-1 was separated into three tables. Changes Document No. ORAUT-TKBS-0055 Revision No. 03 Effective Date: 01/03/2012 Page 3 of 90 were made to Table 5-7 (now 5-8) to clarify and correct intake values. Wording was added to Section 1.3 to caution the Dose Reconstructor on when to label the DR as a partial DR. Incorporates formal internal and NIOSH review comments. Constitutes a total rewrite or the document. Training required: As determined by the Objective Manager. Initiated by Jackson R. Ellis. 01/14/2011 02 Revision initiated to include SEC-00166. Section 1.3.3 and Table 1-3 added. Section 2.1.6 updated to note the end of hot cell operations in the Research Building. Paragraph added in Section 5.0 to discuss SEC-00166. Section 5.1.1.3 updated with internal intake information from SEC-00166. Table 5-4 and 5-8 updated with updated intake rates. Section 5.4.1 updated to remove statement that intakes from the Research Building hot cell would be negligible. Removed A&A point. Added SEC-00166 to the reference section as NIOSH 2010. Incorporates formal internal and NIOSH review comments. Constitutes a total rewrite of the document. Training required: As determined by the Objective Manager. Initiated by Jackson R. Ellis. 01/03/2012 03 Revision initiated to include SEC-00185. Section 1.3.4 was added. Section 1.3 edited to update partial dose reconstruction information and to introduce new SEC. Sections 1.3.1 and 1.3.2 were edited to show inclusion of all workers in those SECs. Expansion of class was inserted in sections of the document as necessary. Section 5.4.1 edited to state environmental doses should be applied to certain Research Building workers. Battelle 2006a was updated to Battelle 2011 and Battelle 2006b was cancelled and replaced with other references. Changes were made to several sections and tables in Sections 5.1 and 6.3. Section 6.3.1.2 was updated to reduce missed dose component of beta doses in Table 6-7. Incorporates formal internal and NIOSH review comments. Constitutes a total rewrite of the document.
