Better integration of radiation protection in modern society.

Until the late thirties, the known effects of radiation were the injuries to the superficial tissues, the changes in the blood and derangement of internal organs. Because of the existence of thresholds for the appearance of these effects the corner stone of radiological protection was the limitation of exposure below a level considered as tolerable to avoid any dangers of over exposure From the forties, the recognition of stochastic effect, coupled with the uncertainty concerning the existence of a threshold for this category of effects, led the radiological protection community to progressively adopt a prudent attitude and to add to the limitation of exposure the objective of keeping doses to the lowest possible level. From that time, one of the key question of radiological protection has been to find a reasonable compromise to satisfy both the objective of keeping doses as low as possible and of preserving the viability of medical, industrial and nuclear activities considered as beneficial to the welfare of societies. The paper presents the march of thought which, over half of a century, attempted to translate into practical recommendations this quest.
