ofe - GA SE VS TIME Project Officer - P. Brown (P. Brown) Objective To obtain gamma rates vs time for various distances a nuclear detonation. Instrumentation Gamma exposure rates were obtained using scintillation ctors set one foot above ground. The detector outputs were réeé as a function of time on continuous recorders. Instrument stations on Bokobyaadaa and Nama had been Rr oyed by blast from GBPse:oration, making it impossible Bp Snstall instrumentation for close-in measurements. Stations were installed on Airukiiji, Airukiraru and i Islands, Bikini Atoll, for the detonation of the 7 | Al! etations operated, and showed negligible gamma nt wetes for the period of sero time to plus 36 hours.
