Stee my Figure 9. Eneman Camp, Bikini, looking south-southwest, CASTLE. low activity of alpha" on the shot islands and only small "pools” of - tivity within 1,000 feet (305 meters) of the craters formed by the expflosions. These areas were covered with soil during that year; a radioloical Survey in March 1950 showed less than 0.001 R/hr on Enjebi and Aomon ahd an average of 0.002 R/hr on Elereron. On Runit the general radioactivity was 0.0015 R/hr, but some of the old shot tower footings showed 0.012 After a third survey in April and May of that year, B/hr. it was concluded that no possibility of overexposure to gamma radiation existed on any islan@ of the atoll and the wearing of film badges was discontinued (Reference 6]. The GREENHOUSE (1951) detonations were on Enjebi, Eleleron, and apparently left these islands and other areas contaminated. and Rugit The D@G and ITEM tower residues were left in place on Enjebi after GREENHOUSE. Shot GEORGE of GREENHOUSE left a large radioactive crater on Eleleron. MIKE, the first thermonuclear device, detonated on Eluklab in 1952 during Operation IVY, destroyed the island and left an underwater cratdr. 48
