Energy Net on 26 Jul 10"Between 1946 and 1958 the United States tested 66 nuclear weapons on or near Bikini and Enewetak atolls, which had previously been evacuated. Populations living elsewhere in the Marshall Islands archipelago were exposed to measurable levels of radioactive fallout from 20 of these tests. In this carefully considered analysis, National Cancer Institute (NCI) experts estimate that as much as 1.6% of all cancers among those residents of the Marshall Islands alive between 1948 and 1970 might be attributable to radiation exposures resulting from nuclear testing fallout. Due to uncertainly inherent to these analyses, the authors calculated a 90% confidence interval of 0.4% to 3.6%. Why did the NCI investigate this exposure? In June 2004, the U.S. Senate Committee on Energy and Natural Resources asked the NCI to provide its expert opinion on the baseline cancer risk and number of cancers expected among residents of the Marshall Islands as a result of exposures to radioactive fallout from U.S. nuclear weapons tests that were conducted there from 1946 through 1958. In September 2004, the NCI provided the Committee with preliminary cancer risk estimates and a discussion of their basis in a report titled Estimation of the Baseline Number of Cancers Among Marshallese and the Number of Cancers Attributable to Exposure to Fallout from Nuclear Weapons Testing Conducted in the Marshall Islands. That analysis was based on a number of conservative assumptions designed to avoid underestimating the actual cancer risks and used information that could be collected quickly to provide a timely response.
