The film badges of three men indicated exposures of 859 95, and 96 R. These individuals are believed to have worked aboard an LCM alongside the Belle Grove. During the washdown of the Belle Grove, consiflerable water reportedly accumulated in the LCM alongside. Subsequently,| these individ- uals were believed to have worked on decontaminating the LCE. Their expo- sures were reportedly a result of concentrated fallout in tHe LCM. ough investigation, however, failed to reveal how they could this much radiation. Thor- have received It was later concluded that some discrppancy in badg- ing or wearing of film badges must have occurred. Careful amination of the badges by densitometer revealed nothing unusual in the r@diation to which they were subjected. Clinical and laboratory studies gonducted on all three individuals at Tripler Army Hospital, Oahu, Territdry of Hawaii, were essentially negative, and they were discharged to duty Reference 16). Task Element 7.3.7.2 (Mine Project Element) The destroyer minelayer USS Shea, the salvage vessel USS Explosive Ordnance Disposal Unit 1, Naval Beach Group 1, and ect 6 made up the Mine Project Element of TG 7.3., which was only for the conduct of Project 3.4, Sea Minefield Neutralizatlion by Means of a Surface Detonated Nuclear Explosion. The project entail laying seven strings of mines, containing 121 in all, at specified dibtances from ground zero. The mines were inert-loaded, but otherwise functfonal, with a detonator installed to assess the shot's effects on the mines components. After the shot, the Mine Laying and Recovery Element, recovered 100 mines and turned them over to the Mine Readying 3.7.3, d Analysis Element, 7.3.7.4, which recorded the effects of blast and presqure on each Mine. Forty-eight of the test mines were returned to the Unite for further study. on 26 April. The project was confined to one shot, UNION} Tables 79, 80, and 81 describe activities of the States detonated Beclaimer, the Shea, and the USS Terrell County during the CASTLE test serdjes.
