prehensive air sampiing during 12 consecutive months under conditions closely approximating human habitation and soil disturbance would provide more accurate data on which to base inhalation exposure estimates. e The inewetax 2eopie aivise 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 lens water sampling, analysis, and assessment program requires sampling through a full rain-dry seasen cycle, 12 consecutive months at a minimum. Arrangements for sampling fresh water lenses are 7 J ode oy ’ 5 i : J / 4 being made. ; #. wae le anrhl he Nenadwen FR ‘ e CG, It is the opinion of the Task Group that the results of additional air sampling or lens water sampling probably would not significantly change the dose estimates in NVO-140 nor change the recommendations of this Task Group. RADIATION CRITERIA RECOMMENDED BY THE TASK GROUP A review of the radiation protection standards and guides considered by the Task Group to be applicable to Enewetak is presented in Appendix III. This review indicates that the numerical standards and radiation protection philosophy of beth national and intemational standards bodies are similar. G04
