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.
The United States dropped two atomic bombs, the first on Hiroshima and the second on Nagasaki (August 6 and 9, 1945). The results were horendous. Japanese scientists were at the time working on an atmic bomb.This was of course secret and only a small number of officvials and ciebtisdts were aware of the work.he American Manhattan Program was the largest weapons development program in history. It was initiated by President Roosevelt when work done by German physicists led to concern that the NAZIs might build an atomic bomb.
