High radiation levels found in giant clams near U.S. nuclear dump in Marshall Islands « Antinuclear
Researchers have found high levels of radiation in giant clams near the Central Pacific site where the United States entombed waste from nuclear testing almost four decades ago, raising concerns the contamination is spreading from the dump site’s tainted groundwater into the ocean and the food chain.
He said isotopic analyses indicated the lagoon contamination was from residue from the initial nuclear weapons testing.
Between 1946 and 1958, the United States tested 67 nuclear devices in the Marshall Islands, including 44 in Enewetak Atoll, one of the nation’s 29 coral atolls. Although the Marshall Islands were home to only 6% of the total number of tests conducted by the United States, it bore the brunt of more than half the total energy yield of all U.S. nuclear weapons testing.
Much of the fallout from those events is now entombed within Runit Dome. According to a photograph taken of Hamilton’s presentation slides, the 377-foot-wide crater in Enewetak Atoll contains groundwater samples with radiation levels 1,000 to 6,000 times higher than those found in the open ocean.
