In 1958 , the United States quiz the 18 - kiloton “ Cactus ” atomic twist on Runit Island in the Pacific . 20 year later , Cactus ’ 350 - foot - wide volcanic crater was filled with radioactive soil and covered with a 100,000 - substantial - human foot concrete noodle . bad vacation ever ?
The $ 239 million Cactus Dome , which is on Runit in the Enewetak Atoll , holds111,000 cubic yards of radioactive soil and detritusfrom nuclear examination on the Bikini and Rongelap atoll . The dome was construct between 1977 and 1980 and is made of 1.5 - ft - thick concrete . I suppose you could still drop by , but I ca n’t imagine the melodic theme of abide on top of a radioactive landfill holds much appeal . There ’s no gift shop , for one .
