Radiation Dosimetry in Hiroshima and Nagasaki Atomic-Bomb Survivors

TO evaluate the late biologic consequences of the atomic bombings of Hiroshima and Nagasaki, there is an evident need for determination of the type and total dose of radiation received by individual survivors. Since 1956 this problem of radiation dosimetry has led to a collaborative effort between the Atomic Bomb Casualty Commission in Japan and the Health Physics Division of the Oak Ridge National Laboratory.Considerable information is needed before a dose can be calculated with any degree of certainty for the individual survivor. Although good estimates of the general magnitude of radiation associated with atomic explosions exist, the bombs . . .
