In 1998, staff from the U.S. Centers for Disease Control and Prevention (CDC) made a comparison study to compare the amount of radioactive Iodine-131 at four different radiation-polluted sites, measured in curies (1,000 curies of Cesium-137, as found in a radiation therapy machine, could produce serious health effects in a direct exposure of just a few minutes). The CDC team reported its finding that the atmospheric release of curies of Iodine-137 at the Hanford nuclear processing plant was 739,000 curies; at Chernobyl the release was 40 million curies; at the Nevada bomb test site, 150 million curies; and in the Marshall Islands, 6.3 billion curies (more that 30 times as much radiation as the other three sites combined).
The Republic of the Marshall Islands is ranked #5 in the world among countries with the highest health costs as a percentage of GDP -- behind Liberia, Sierra Leone, Tuvalu, and the United States.
