Occupational Radiological Risks In Uranium Mining : A System Analysis Of Protection Environment

This study is devoted to the improvement of the decision-making process in occupational protection of uranium miners in France. Its purpose is to apply the principles which are recommended by the I.C.R.P. in the field of radiation hazards. These principles, which have introduced the notion of "optimization" in standard setting, suggest the importance of applying cost-benefit and cost-effectiveness analysis to this sector. The objectives here are twofold : to evaluate the present organization of radiation protection on the basis of a simulation model of polluted air flow in the mine (due to the decay of a radioactive gas, radon) and to develop cost-effectiveness analysis of the various radiation protection policies.
