DEVELOPMENT OF RAPID METHODS FOR ASSESSING DOSES FROM INTERNALLY DEPOSITED RADIONUCLIDES.

The article discusses methods used to calculate organ doses from internally deposited radionuclides under the Radiation Dose Reconstruction Program of the U.S. National Institute for Occupational Safety and Health (NIOSH). During the initial phases of the program, calculations were performed using the Integrated Modules for Bioassay Analysis program. However, limitations associated with this program created inefficiencies in the processing of claims. As a result, NIOSH created a suite of tools to expedite the process. The first of these was the Chronic Annual Dose Workbook program, which permits a dose reconstructor to calculate, in a single step, an organ dose that involves up to 255 separate intakes in any combination of radionuclides, intake modes, and absorption types.
