aaBle a a, BRAVO fallout on some Navy ships also resulted in additional pa@rsonnel who had exposures approaching or exceeding the CASTLE MPE of 3.9 Rj To allow for operational completion of the remaining CASTLE shots, it became necessary to issue a number of waiver authorizations permitting expbsures of as much as 7.8 R. In a limited number of cases, even this level] was exceeded. As a result of BRAVO, 21 individuals on the USS Philip (DDE-498] 16 on the USS Bairoko (CVE-115) sustained small skin lesions resembhing burns that were definitely classified as beta burns. The affected person- nel received radiological contamination while on the weather deck of tioned near ventilation blowers. and sta- These all healed without complica The USS Patapsco (AOG-1), a Navy gasoline tanker, which was approxi 180-195 nautical miles (333-360 kilometers) northeast of BRAVO's gr zero at the time of detonation, received fallout as it returned to Harbor. Exposure estimates as high as 18 R are possible, assuming individual was on deck 24 hours a day with the ship retaining 100 of all fallout radioactivity and using the highest reading from rad Surveys. For an individual who spent only 8 hours a day on deck and hours a day inside, and assuming that the storm conditions washed o 16 50 percent of the activity en route, the estimated dose is 3.3 R. The other five CASTLE detonations, though extremely important a weapon tests, did not produce significant, unexpected personnel radifation exposures. While small numbers of personnel at CASTLE did receive exposures} in excess of imposed standards, by far the largest portion did not. Inj fact, the radiation exposure for JTF 7 personnel at CASTLE averaged about 1.7 R. The recorded CASTLE exposures are summarized in the table onjthe following page. plaid MAM RN, negative" or “generally negative." sh The results of these medical observations were reported as "essent¥Jally
