Abstract |
The EPA Science Advisory Board's (SAB) Radiation Advisory Committee has reviewed EPA's Low-LET Risk Estimate for Regulatory Purposes and determined that, on an interim basis, the nominal central estimate of 400 fatal cancers and a range of 120-1200 additional fatal cancers per million persons exposed to one rad of low-LET radiation is acceptable. However, several important reports and radiation risks are expected within the year which could alter the understanding of their magnitude. The reports are based, in part, on new information from Japan on the survivors of the atomic bombing of Hiroshima and Nagasaki. The SAB urges EPA to take the findings and conclusions of such reports into account in the development of final regulations on radionuclides in the environment. |
