THE ATOMIC Bomb Casualty Commission (ABCC) was established in Hiroshima in 1947 and in Nagasaki in 1948 by the US National Academy of Sciences, National Research Council (NAS/NRC) based on President Truman's directive to initiate a long-term and comprehensive epidemiological and genetic study of the atomic bomb survivors.1 The Japanese National Institute of Health under the Ministry of Health and Welfare joined the ABCC 1 year later to assist in the studies and improve the cooperation of the survivors.
This arrangement continued for 28 years until it was replaced in 1975 by the Radiation Effects Research Foundation (RERF), a nonprofit Japanese foundation binationally managed and supported with equal funding by the governments of Japan, through the Ministry of Health and Welfare, and the United States, through the NAS/NRC under contract with the US Department of Energy (and its predecessors). Thanks to the cooperation of the survivors and the contributions
