nuclear weapon test

Ivy Mike (Eniwetok atoll - 31. October 1952)

After completion of the Second World War the UN decided that the use of areas of Marshall Islands for security needs of the USA is not subject to any restrictions. Thus the isle became to 31. October 1952 strongly in pulled, when the United States tested there its first hydrogen bomb Ivy Mike with an explosive yield of 10 megatons. Further 43 nuclear weapon explosions followed in the further area, so that the islands were strongly radioactively contaminated . During the atomic bomb tests were stationed approximately 11,000 US technicians, Wissenschafter and military on Eniwetok. For the investigation of the explosion clouds of the bomb tests 1957/58 also some rockets (predominantly of Rockoons) were started [1].

three islands of the remaining radioactive waste were cleaned for Eniwetok lagoon 8.9 Mt [ work on ]. The contaminated earth was wide cleared away and poured together with in-collected garbage in two Explosionskrater. The Krater originated in to 5. April 1956 with the LaCross and to 5. May 1958 with the Cactus explosion on the Inselchen Runit. Although they were afterwards zubetoniert, is to be measured to today still ionizing radiation, particularly because of plutonium. Runit is prohibited area and can only in 24,000 years (radioactive half-life) again be released.
