qn were exposed at the 60 foct level of 4 photographic tower about 150 feet from the main exposure site. On Fnyu (Nan) (site 412.01), 10 rabbits were also exposed without filter or shutter protection at the 200 foot level of a photographic tower, RESULTS No burns were sustained in the 103 rabbits and 4 monkeys exposed to this shot. It was estimated that 7-19 cal/em* would be received at the exposure sites on Bikini (Yow) and 2-3 cal/em® on nyu (Nan). Actual measurements, however, showed that Ices than 2 cal/em® was reccived at Bikini (How). The actual dose at Tnyu (Nen) is not know, but is presumed to be correspondingly low. The extremely low radiation doszs are ascribed to rainstorms between the shot and the exposure sites. confirms? the presence of heavy rainfall over Bikini (Eow) at shot time. CONCTISIONS The results of thie study are inconclusive, apparently because of extremely high atmospheric attenuation due to rainstorms at shot time, ~49 ~ aR A Se
