reading on YAG-39 reached levels in excess of 400 R/hr about 17 minutes after the detonation, The washdown system that had been installed to decontaminate the surfaces reduced this level to 0.040 R per hour 30 minutes after the detonation. Recorded shipboard levels were less aboard YAG-40. Both of these vessels had 48 asSigned personnel. However, at the time of detonation only about 12 crewmembers and project personnel were aboard each YAG. Six crewmembers aboard YAG-39 and one crewmember aboard YAG-40 received recorded exposures other than zero. In each instance, recorded film badge readings for crewmembers did not exceed 0.130 R.
