As far aS exposure to external gamma radiation is con- cerned, our calculations have shown that exposures should not exceed 60-70 millirem per month. To date, in the hundreds of film badge readings taken, only 44 positive values have been recorded, with the highest being 70 millirem, and only 4 (70, 70, 50, 42 millirem) exceeding 10% of the permissible monthly exposure of 416 millirem. As far as internal exposures, our intensive measurement Program has shown no evidence of any intake whatsoever. In the thousands of hours of air sampler operation, no airborne radioactivity above background has been detected. No indication of internal exposure has been detected in analysis of face mask filters, and bioassay urine samples on departing workers with a potential for exposure have. all been negative. In regard to your suggestion that the Services might want to consider using only volunteers in the cleanup work, this is being done insofar as practicable. Except for a few of the DoD personnel (such as the Joint Task Group headquarters), aSSignment to the Atoll is for a 150- to 170- Gay temporary duty period. The few exceptions are assigned for a one-year tour. Each Service handles its personnel assignment slightly differently, but in each case, every effort is made to obtain volunteers. Quite obviously it would be impossible to man such an effort with the requisite skills, over the nearly three-year life of the project solely with volunteers. To date many, though certainly not all, , of the personnel engaged have been volunteers. The participants are fully apprised of the known and potential radiological risks involved in the operation. Upon arrival, all personnel receive an initial orientation covering the operation and the potential hazards, not only radioactive, but also sunburn, coral, fish and others. Those who are to be engaged in cleanup of radioactive materials undergo additional training covering operations in a controlled area and the risks expected. Further, each Service conducts its operations under close leadership and supervision, and in accordance with the pertinent directives, regulations, and standard operating procedures.
