The DS86 dosimetry used by the Radiation Effects Research Foundation, in re-evaluating radiation exposure risks from the atom bomb survivor lifespan studies, has led directly to a significant reduction in the maximum permissible dose recommended by the International Commission on Radiological Protection. In the case of uranium miners the contribution to the total dose resulting from the inhalation of radon daughters continues to be assessed in accordance with the procedures recommended in ICRP Report 47, which means that there has been no change in the maximum permissible radon daughter exposure limit. ICRP intends to review this situation once the new report of their task force on lung dosimetry has been adopted. This paper suggests that the direct epidemiological data on the risks of radon daughter inhalation is more satisfactory than indirect estimates of risk based on a lung dosimetry model, and that this direct evidence does not justify any increase in the presently accepted risk factor associated with radon daughter inhalation.
