First approved issue. No training required. Initiated by Donald E. Bihl. 01/06/2006 00 PC-1 Approved page change revision. Incorporates changes for environmental ambient external and internal doses for unmonitored, non-radiological workers as a result of formal internal review and informal OCAS comments. Page change includes new content added to pages 7 and 22 (Sections 1.0 and 5.1.4). Removed definition of unmonitored worker on page 26 (Section 6.4.1). Minor revisions were made to pages 17, 18, 19, and 23 (Sections 4.0, 5.0, 5.1.2, 5.2 and 6.2.1). As a result of NIOSH formal review, incorporates Attachment A on pages 43–46, into Site Profile. This attachment describes technical basis of ambient environmental dose estimate for unmonitored workers. No sections were omitted. Retraining is not required. Initiated by Jack J. Fix.

Neton, Associate Director for Science 01/06/2017 01 Revision initiated to incorporate changes to include information from the SEC-0210 Petition Evaluation Report and updated medical X-ray organ dose determination using guidance in ORAUT-OTIB-0006. Affected all sections. Expanded on the Machining Area operations, ThO2 powder sources, and to expand on Mg-Th operational periods. 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.
