3.)Dose Assessments As spelled out in the P.L. 96-205 a radiological dose assessment at the 4 atolls is required at least once every 5 years. A dose assessment must include the evaluation of the following exposure pathways: 1. External gamma 2. Terrestrial foods 3. Marine foods 4. Drinking water 5. Inhalation Maximum dose rates and 30 and 50 year integral doses should be calculated. The results should be broken down by pathway and also given as a total dose from all pathways. Annual body burdens should also be calculated .for pathways 2 thru 4. The dose models used to calculate the doses must be currently accepted models from the scientific literature. Specifically, because '37 66 and 90<,. contribute most of the dose, the whole body and bone marrow dose models for estimating doses from ingested W3leq and 905, must be realistic. Inhalation pathway dose estimates must be based upon sound resuspension models for an atoll] ecosystem. The dose assessment methodology must also be able to generate predicted doses for islands and atolls where locally grown subsistence foods are presently not available. Many of the demands for dose aSsessments involve this kind of situation and there must be a predictive capability to estimate doses when only radionuclide concentrations in soil are available. most essential feature of the required dose assessment methodology. 44 This is a
