Atomic Bomb Casualty Commission, 1945-1982

In November 1946, President Harry S. Truman issued a directive authorizing the NAS-NRC to undertake the long-term study of the survivors of the atomic bombings of Hiroshima and Nagasaki. Just prior to Truman's directive, a five-man commission, operating under the auspices of the National Research Council's Division of Medical Sciences and calling itself the Atomic Bomb Casualty Commission, had been sent to Japan to conduct a preliminary survey of the situation.

The Atomic Bomb Casualty Commission (ABCC) was officially established under the direction of the Research Council's Division of Medical Sciences in March 1947. The ABCC, which was responsible for carrying out research in the field, was overseen by the division's Committee on Atomic Casualties, which later became the Advisory Committee on ABCC. Operations were funded by the newly created Atomic Energy Commission's Biology and Medicine Division.

The survey findings of the original five-man NAS-NRC commission, communicated in December 1946, made up the ABCC's first report. The first research program proper set up by the ABCC was a hematological study, begun under James V. Neel in March 1947. By 1950, the ABCC had a number of departments in operation, and had established a series of studies that would include research on radiation cataracts, leukemia and other cancers, survivors' aging and mortality rates, sex ratios of survivors' offspring, and genetics.

Logistical and organizational problems of the early ABCC were such that by 1955 it appeared that the program would have to be terminated. Toward the end of 1955, a committee under the direction of NAS Member Thomas Francis was sent to Japan to assess the ABCC and its programs; on the committee's recommendation a new and more effective study program was implemented. By 1957 George B. Darling of Yale University was made director, and it was under his long leadership -- ending only in 1972 -- that the ABCC was able to reorient and stabilize its operations. An Adult Health Study involving biennial examinations of survivors was soon established, followed not long after by new cytogenetic studies. It was also under Darling's leadership that the ABCC instituted bilingual technical protocols and increased the participation of the Japanese National Institute of Health in ABCC studies.

By the early 1970s, constraints imposed by increased operating costs began to make themselves felt. In response to requests that the Japanese Government increase its support of the ABCC, a new, binational private foundation, the Radiation Effects Research Foundation (RERF), was negotiated into existence, and in 1975 it replaced the ABCC while continuing the latter's programs.

The ABCC General Report of January 1947 is available here.
