| INTRODUCTION |

Extensive studies of atomic bomb survivors in Hiroshima and Nagasaki and of persons exposed for medical reasons have resulted in a wealth of knowledge about the health effects resulting from radiation exposure at relatively high doses and dose rates. The availability of individual estimates of dose has made it possible to quantify dose-response relations and to estimate risks from exposure at low doses and dose rates. These estimates form the basis for setting radiation protection standards (1
As Sont et al. (4
) note, the primary reason for studying nuclear workers is to allow a direct assessment of risks resulting from exposure to radiation at low doses and dose rates. The atomic bomb survivor cohort and some of the medically exposed cohorts include persons exposed at low doses and have provided evidence of risk for doses as low as 0.1 Sv (5
). However, estimates from these studies
