In Nagasaki, the initial nuclear radiation only spread one and six thousandths of a kilometer (The Committee for the Compilation of Materials on Damage Caused by the Atomic Bombs in Hiroshima and Nagasaki, 1981). The reason why the nuclear radiation was not the main caused of deaths or injuries was that the atomic bomb was detonated so high in the atmosphere; approximately five hundred and seventy meters in Hiroshima, and approximately five hundred and ten meters in Nagasaki (Outlaw Labs). Even without causing many deaths the nuclear radiation probably caused the most serious effects. Those with definite proof were those of increased rates of cataracts, leukemia, cancer of the thyroid, cancer of the breast, cancer of the lungs, cancer of the stomach, and mental retardation on babies in utero. Those that had substantial but not definite proof were those of tumors of the esophagus, tumors of the colon, tumors of the salivary glands, and tumors of the urinary tract organs. Those that had no definite nor substantial proof were those of increased rates of birth mortality, birth defects, infertility, and susceptibility towards illnesses (Physicians and Scientists on Nuclear War, 1981). The total number of people effected by the nuclear radiation was estimated to be thiry-five thousand people in Hiroshima, and twenty-one thousand people in Nagasaki (The Committee on Damage Caused by the Atomic Bomb in Hiroshima and Nagasaki).

Either the blast, the thermal radiation, or the nuclear radiation from an atomic bomb explosion will have severe effects on both humans and on the environment in which they live in. The only two cities that have ever experienced having an atomic bomb being exploded on them were the Japanese cities of Hiroshima and Nagasaki during World War II. In Hirsohima, the total number killed was one hundred and eithteen thousand six hundred and sixty-one. The total number severely injured was thrity thousand five hundred and twenty-four. The number slightly injured was forty-eight thousadn six hundred and six. The total number missing was three thousand and six hundred and seventy-seven. In Nagasaki, the total number killed was seventy-three thousand eitght hundred and eighty-four. The total number severely injured was seventy-four thousand nine hundred and nine. The total number slightly injured was one hundred and twenty thousand eight hundred and twenty (The Committee for the Compliation of Materials on Damage Caused by the Atomic Bombs in Hiroshima and Nagasaki, 1981).
