Studies on the life spans of atom-bomb survivors

Journal Article:

Abstract

A shortening of whole life as late injuries of atom-bomb survivors was discussed from the aspects of aging and the studies on the causes of leukemia and cancers. Twenty-one thousands four hundreds and forty-seven of 109000 subjects died during the period between 1950 and 1970. Mortality by exposure doses presented a high value with exposure doses. Mortality of subjects which had received exposure doses of more than 200 rads rose to a level which was 1.27 times in all causes of deaths of the control which had received exposure doses of 0 to 9 rads, and it showed 1.32 times in all deaths of sickness, 18.3 times in leukemia, and 1.48 times in death from cancer. Mortality due to leukemia decreases after 1950-1954, but in the group which had received exposure doses over 100 rads, the mortality was significantly higher than that in all districts in Japan. The shape of dose-reaction curve in Hiroshima was different from that in Nagasaki. In the same dose, mortality due to leukemia in Hiroshima was higher than that in Nagasaki. The younger the age at exposure was, the higher the risk rate of occurring cancer was. Especially, the risk rate of cancer was high  More>>

The younger the age at exposure was, the higher the risk rate of occurring cancer was. Especially, the risk rate of cancer was high in the patients who were exposed to atomic bomb during the age of 0 to 9 years old. Mortality due to cancer increased with the dose. Cancers which statistically showed higher mortality than that in the control group are lung cancer, cancer of the breast (100-199 rad), carcinoma of the esophagus, cancer of the urinary organ (200-299 rad) and gastric cancer (over 300 rads). There are not so clear difference in the mortality due to cancer between Hiroshima and Nagasaki, comparing with the mortality due to leukemia.}
