• Description:
  To estimate the probability of causation in an occupational radiation exposure compensation program, it is necessary to reconstruct the dose for the tissue or organ that was diagnosed with a primary cancer. In occupational monitoring programs, dosimeter badges are commonly used to assess compliance with prescribed exposure limits. Because the dosimeter badges measure the dose delivered at a specific point on the body, and not to the actual organ, a method has been developed to convert the regulatory compliance dose (monitored dose) to a dose to the affected organ or tissue. The method takes into consideration: 1) the response of the monitoring device; 2) the exposure photon energy; and, 2) the exposure geometry. The combination of these three factors results in a time, facility, and task specific organ dose conversion factor (DCF). This paper describes the technical approach used in developing these organ specific dose conversion factors. Examples of the relative importance of accounting for differences between regulatory compliance dose and the organ dose are provided for selected exposure conditions. [Description provided by NIOSH]
