Abstract

The importance of determining a realistic value of the dose and dose-rate effectiveness
factor (DDREF) is emphasized in estimating the cancer risk of radiation at low dose and low dose rates from cancer data at a high dose such as this from A-bomb data. The currently adopted value for this factor, 2, is too small and does not reflect the true feature. From analysis of non-tumor doses of radiation on experimental and epidemiological studies, the appropriate value of this DDREF value is estimated to be 10 or higher, a number that may better serve for realistic radiation protection rules.
