Developments in Tissue Reactions and Related Science

Recent work of ICRP, especially in ICRP Publication 118, has shed light on the complexity of tissue reactions (deterministic effects) due to exposure to radiation. New scientific evidence on cataracts and circulatory disease suggesting effects at levels considerably lower than previously understood has raised the profile of tissue reactions. Continued research is necessary to improve the understanding of the risk and mechanisms of cataract induction and circulatory disease related to radiation exposure especially below 0.5 Gy.
