Abstract

Correlation between natural background radiation exposure rates and cancer mortality rates in 46 Japanese prefectures was statistically studied over the period between 1968 and 1978. With regard to the correlation between natural background radiation exposure rates and cancer mortality rates, statistically significant positive correlation coefficients were observed in most cases of cancers with only a few exceptions.
