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.
Exposure to Very High Levels of Radiation. People who are exposed to very high levels of radiation are much more likely than others to develop leukemia. Very high levels of radiation can be caused by: 1  Atomic bomb explosions (such as those in Japan during World War II).2  Nuclear power plant accidents (such as the Chernobyl accident in 1986).xposure to Very High Levels of Radiation.
