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 first Atomic Bomb (called little boy) dropped was on  August 6, 1945 on the city of Hiroshima. The second atomic bomb  (called fatman) dropped was on Nagasaki three days later.  The United States dropped these bombs on Japan in order to end  World War II.Then on August 14, 1945, the Japanese surrendered.he was ended  only 1 day after the second bomb was dropped. The bombs caused  Japan to surrender. Both a-bombs (atomic bombs) caused about  128,000 people to die and over 120, 000 people suffered from  radiation sickness and cancer.
