Lingering Radioactivity in the Marshall Islands<\/h1>\r\n

The Marshall Islands, a series of remote atolls in the Southern Pacific Ocean were used as ground zero for the testing of nuclear bombs by the US Government Department of Energy. The remote islands, at the time a US protectorate, saw 66 tests over 12 years starting in 1946. With a combined total explosive power of 100Mt many long- and short-lived radionuclides soon contaminated in the ocean and soils on and around the tropical islands. Caf\u00e9 Thorium visited these islands in 2015 to track the fate of some of these.<\/p>\r\n

Following nuclear testing, perhaps not surprisingly, the islands were evacuated due to the health hazards associated with radioactivity found there. In 1977 an effort to decontaminate the islands began. The US Military mixes more than 111,000 cubic yards of contaminated soils and debris from the various islands with cement and buried it in a 30 ft. deep, 350 ft. wide bomb crater on Enewetak island. Dubbed the Runit Dome they then enclosed it in cement, however the bottom is not sealed resulting in tidal waters moving through the material.<\/p>\r\n

Work on the islands involved testing groundwater, seawater and sediments for a variety of radionuclides.<\/p>\r\n
