Abstract:

An attempt was made to document the gamma dose rates from Little Feller I, Little Feller II, and Johnie Boy events using SEMIRAD dose rate measureing devices. The recording equipment was housed in a bunker constructed of a 15-ft. length of ten-foot-diameter corrugated metal pipe CMP. The bunker was installed and, with in a period of two weeks, moved to three differ ent shot sites for participation in the above named events. The experiment failed to obtain the dose rates in each of the events. In Little Feller I, the timing signal was severed prior to zero time. In Little Feller II, the record ing film was unreadable because of an overdose of radiation. In Johnie Boy, the lack of sufficiently intense prompt gamma radiation from this subsurface burst failed to trigger the SEMIRAD detector. The bunker was successful in attenuating radiation, preventing blast damage to the electronic gear inside, and shielding the electronic gear from electromagnetic radia tion. Author
