Development of DOE site profiles to support dose reconstruction.
Health Phys 2003 Jun; 84(Suppl):S222-S223
During the performance of soe reconstructions, individual dosimeter data and measured intakes (through bioassay analysis, in vivo measurements, etc.) should be used whenever possible and given precedence over area monitors, survey data, or source term data. However, this is not always possible. A person's exposure record may be incomplete, missing, or perhaps the individual was not monitored properly or at all during the time of employment. The development of site profiles for all of the major Department of Energy sites is a necessary tool for completing dose reconstructions. These profiles serve several purposes: 1) they provide a brief, general overview of specific DOE sites; 2) they identify the facilities on site with a brief description of the processes and radionuclides of interest; and 3) they provide very important support information for the dose reconstructor to use if the monitoring data are inadequate or not available. These are technical basis documents that include specific information and assumptions that can be used by the dose reconstructor. Each claim is reviewed individually. Depending on the situation, important parameters may include facility monitoring data (by radionuclide, mechanism, year, location within a facility); medical x-ray exposures and techniques used; environmental measurements (by area on site, radiation type, energy range); MDAs for different radionuclides;. specific source terms within each facility or process; and specifics of the dosimetry program itself as it has evolved over time. Resources include technical basis documents for the external and internal dosimetry programs, facility descriptions, environmental reports, safety analysis reports, and other reports that have been written to describe the workplace environments within the facilities. For example, the Site Plan for the Savannah River Site provides the above-referenced information for five heavy-water reactors (no longer operational) and other facilities in seven areas on the site.
