this document in PDF PDF 1.1 MB (90 pages)

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 canceled and replaced with other references. Changes were made to several sections and tables in Sections 5.1 and 6.3. Section 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.

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.

Below is a list of links to Ames Laboratory PER and PEP documents. 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 the Ames Laboratory:

At the current time, worker outreach activities have not been scheduled.
