Abstract:
We would like to explain the effects of radiation on human health and discuss the actual effects of the contamination with radioactive material present in Tokyo. Currently, external exposure doses are within the allowable range in Tokyo and will have no adverse health effects on adults or children. As for internal exposure doses, there will likely be no problems as regards our ordinary dietary intakes. However, hot spots of Cs-134, Sr-90 and others should be monitored further.
