-Nuclear fuel cycle Occupational radiological safety in uranium mines and mills by J.U. Ahmed* Uranium mining and milling industries are growing

Uranium mining and milling industries are growing rapidly in many countries and this trend is likely to continue with the increasing demand for nuclear fuel. The problems of radiological hazards in this part of the nuclear fuel cycle have received considerable attention in recent years because of the epidenuological evidence of lung cancer among uranium miners, mainly smokers. The hazard is not limited to uranium mines only: investigations having shown that the same radiological constituents that have caused lung cancer among uranium miners, i.e. radon and its decay products, occur in other types of mines; and, in some instances, they occur in sufficient concentration to cause occupational illness.
