decreasing radionuclide inventory and detailed ground water studies will be focused at the 4 specified atolls and will be necessary only on a limited basis at other atolls. Estimated incremental costs to conduct the program outlined for the 4 atolls specified in P.L. 96-205 at other atolls are listed in Appendix B. A general description of the required effort is listed by program. }.) Requirements for Dose Assessments a) Terrestrial and marine food sample collection. Soil sample collection and ground-water and cistern-water sample collection will be required at each atoll which is included for monitoring and dose assessment. b.) Diet and Consumption Dietary and consumption habits wil] have to be evaluated for each added atoll] in order to develop dose assessments that are atoll specific. c.) External Gamma Measurements External gamma exposure rates at other atolls are very low and need only to be measured once sometime after 1985 to verify the external measurements of the Northern Marshall] Island survey and the expected decrease. 47
