Revision Includes: Initiated to add text in Section 2.0 and remove information regarding nonuranium radionuclides in Sections 3.0 and 5.0 to incorporate SEC evaluation report recommendation to not reconstruct nonuranium internal dose. Moved Figure 2-1. Incorporates formal internal and NIOSH review comments. Added reference for employee statement regarding X-rays. Constitutes a total rewrite of the document. The recently designated residual period is identified. Section 5.0, Estimating Exposures From Residual Radioactivity, expanded to address dose reconstruction methodologies for exposures received during the residual period. Added Attributions and Annotations section and additional references.

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 Allied Chemical Corporation 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 Allied Chemical Corporation:

  • June 22, 2006
    Meeting with United Steelworkers of America (USW) Local 7-669, Metropolis, IL
