Environmental protection against ionizing radiations: the way proposed by the ICRP, its origin and its analysis

Face to the conceptual lack relative to the radiation protection of environment and when numerous legislative texts begin to come about the species protection, the ICRP began a thought that aims to recommend a frame according to evaluate the impact of ionizing radiations on environment. This choice emphasizes the parallel man-environment by putting the two parts to protect at the same level. The unknown part is essentially the interactions of ecosystem but the future knowledge will be progressively integrated as they will be known. (N.C.)
