Abstract

The International Commission on Radiological Protection (ICRP), Committee 1 (C1) considers the risk of induction of cancer and heritable disease (stochastic effects) together with the underlying mechanisms of radiation action. C1 also considers the risks, severity, and mechanisms of induction of tissue/organ damage and developmental defects (deterministic effects). The committee was significantly revamped in 2013 and last met in Abu Dhabi in October of 2013. C1 evaluated progress on two ongoing Task Groups (TG’s); TG 64 “Cancer Risk from Alpha Emitters” and TG 75 “Stem Cell Radiobiology”. Following approval from the Main Commission (MC), C1 established two new TG’s; TG 91 “Radiation Risk Inference at Low Dose and Low Dose Rate Exposure for Radiological Protection Purposes”, and TG 92 “Terminology and Definitions”. Here I will present a synopsis of the current status of C1 and outline the tasks C1 may undertake in the future.
