Internal Dose Assessment
The methodology of References 13 and 14, together with the FIIDOS code (Reference 15), provides a means of calculating the internal dose to a given organ or tissue, based on existing intensity measurements, film badge readings, or dose reconstructions. For internal exposures, airborne radioactive particles are assumed to be fully respirable with an Activity Median Aerodynamic Diameter of 1 micrometer (Reference 16). Based on radiochemistry data for Shots DOG, EASY, and ITEM, and the aforementioned intensity measurements, the veteran’s (50-year) committed dose equivalent to spinal nerve tissue from the inhalation of descending nuclear debris in the fallout on Enewetak Island is less than 0.01 rem. For the inhalation of resuspended fallout, a resuspension factor of 10−5m−1 is applied to the assumed 60 percent of the time spent outdoors, resulting in less than 0.01 rem to spinal nervous tissue.
Internal Dose Summary: The veteran’s total committed dose equivalent to spinal nervous tissue is less than 0.1 rem.
