Site Profile
- Site Profile for Atomic Weapons Employers that Refined Uranium and Thorium
(Approved December 13, 2006)
 PDF 446 KB (75 pages)
About this Document: This technical basis is established for the reconstruction of radiation doses of workers at AWE sites which refined uranium under contract to the United States government from 1942 to 1958. This document covers the generic aspects of uranium refining and the data are useful where no other dosimetry data exist. Site specific appendices are included that provide information that apply to only the identified site.

Program Evaluation Reports (PERs) and Program Evaluation Plans (PEPs)
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.
At the current time, no PERs or PEPs specific to United Nuclear Corp. have been developed. However, we have developed PERs and PEPs that pertain to
multiple sites. To view all PERs and PEPs that have been developed, please refer to the Program Evaluation Reports (PERs) and
Program Evaluation Plans (PEPs) page.

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.
Below are the Worker Outreach Activities for United Nuclear Corp.:
At the current time, worker outreach activities have not been scheduled.
