Introduction. The atomic bomb survivors of Hiroshima and Nagasaki are a significant population for the study of radiation induced human leukemia. Whole body irradiation is most likely the cause of the leukemia caused by the atomic bomb radiation.[1] Follow-up of Japanese adult survivors of Hiroshima and Nagasaki have revealed abnormally high rates of cancer, persistent chromosomal aberrations in circulating lymphocytes, and lenticular opacities.3] Finally, children of atomic bomb survivors, who received exposure in utero ionizing radiation, had diminished stature, small head size, mental retardation, and subsequent seizures. [3] Study of the aforementioned groups has provided essential knowledge on the health effects of atomic bomb radiation.
Excess leukemia was the earliest delayed effect of radiation exposure seen in A-bomb survivors.Japanese physician Takuso Yamawaki in Hiroshima first noted an increase of leukemia cases in his clinical practice in the late 1940s.This led to the establishment of a registry of leukemia and related disorders and to the initial reports on elevated leukemia risks published in the early 1950s.xcess leukemia was the earliest delayed effect of radiation exposure seen in A-bomb survivors.
