RS oN Project 2.274 Gamma Dose Rate vs Time — P. Brown OBJECTIVE To measure residual gamma radiation intensity as a function of time at land fallout stations, and to measure the initial gamma intensity vs time for a high yield air burst, INSTRUMENTATION The initial gamma dose rate vs time was to be detected by scintillator-photomultiplier detectors with time response to 10 msec, Residual and fallout gamma intensity vs time was to be measured with ionization chambers and associated electronics. Station locations Spread from Bokobyaadaa (Able) through Namu (Charlie) to Fnyu (Nan), and on the YAG's and LST 611. RESULTS Usable data was not obtained for either initial or residual radiation rates vs time. firtre. cr? \ ~ he
