Evaluate the rates and impacts of radionuclides remobilized from the benthic environment to the lagoon water mass and subsequently, to the open ocean; Develop a fundamental radionuclide data base and construct models at the Atolls that will be useful in predicting impacts on components of the aquatic environment; | Furnish data to assist in locating usable sources of groundwater at the Atol] and determine correlations between radionuclide concentrations in the groundwater, soils and various edible plant species; and ° Evaluate the impact of marine plutonium labelled particulates resuspended on the ocean-side reef at the Atolls of Bikini and Enewetak. C. Dose Assessment Program The goals of this program are to: Develop accurate estimates of the maximum annual dose rate and the 30 year integral dose for alternate living patterns at Bikini and Enewetak Atolls. These assessments form a basis for decisions for land-use at the atolls and also serve as a basis for decisions by the people of each atoll. The dose assessments in the Marshall Islands must be as accurate as possible; they must neither seriously underestimate nor overestimate the potential radiological risks associated @ith resettlement of these atolls. 14
