prehensive air sampling during 12 consecutive months under conditions closely approxinating human habitation and soil disturbance would provide more accurate data on which to base inhalation exposure estinates. @ The Enewetak People advise that catchment rainwater is the customary principal source of water for human consumption. Except in emergencies, water from underground lenses is not consumed. Samples of underground water were not obtained during the survey, and radiochemical analytical data on lens water is limited to that obtained from a few samples taken on JANET in 1971. A thorough jens water sampling, analysis, and assessment program requires sanpling through a full rain-dry season cycle, 12 consecutive months at aminimum. Arrangements for sampling fresh water lenses are being made, 6 It is the opinion of the Task Group that the resuits of additional air sanpling or lens water sampling probably would not significantly change the dose estinates in NVO~-140 nor change the reconmmendstions of this Task Group. RADIATION CRITERIA RECOIOSTENDED BY THE TASK GROUP A review of the radiation protection standards and puides considered bv the Task Group to be applicable to Enewetak is presented in Appendix ITI. This review indicates that the numerical standards and radiation protection philosophy of both national and international standards bodies are similar. Vey 4, Shea
