The Effects of Low and Very Low Doses of Ionizing Radiation on Human Health


Book Description

The growing knowledge about the mechanisms of carcinogenesis and the critical analysis of the assumption on which the no-threshold linear relation is based have advanced, but dose-effect relations must be found which optimize the overall epidemiological and experimental data. It is abundantly clear that the standards that will be enforced upon the entry into the force of the International directive no longer enjoy the scientific justifications which made them credible, and that concepts like collective dose and the ALARA (As Low As reasonably Achievable) principle are obsolete. Yet this merely raises, with even greater sharpness, the key question: what can replace them? In this respect, research on the influence of variations in natural irradiation on cancer frequently represent a vital source of information. Radiological protection has entered what some call a turbulence zone, others a renewal. The dogmas on which it lived for more than two decades have been questioned, giving the medical and scientific community a dual responsibility.




Sources and Effects of Ionizing Radiation


Book Description

During the last few years the United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR) has undertaken a broad review of the sources and effects of ionizing radiation. Nine scientific annexes on particular subjects were issued in the UNSCEAR 1993 Report. Two further annexes have been completed, and these comprise the UNSCEAR 1994 Report. In this report the Committee summarizes the main conclusions of the two scientific annexes "Epidemiological studies of radiation carcinogenesis" and "Adaptive responses to radiation in cells and organisms." In addition, the Committee is reviewing the effects of radiation on the natural environment.
