Some Elementary Concepts of Radiation Health and Safety in Underground Uranium Mines

摘要

Some elementary concepts of radiation health and safety in underground uranium mines are discussed. This report reviews the main radiation sources which contribute to the contamination of mine atmospheres and hence to the exposure of mine workers. A brief discussion of the biological effects of ionizing radiation, with special reference to radon and its progeny, is followed by the introduction of the presently accepted radiation indexes for radiation hazard (WL) and radiation exposure (WLM). Finally, a succinct review of the available techniques for radiation control and monitoring in underground uranium mines is complemented by a discussion of various methods of personnel radiation protection, including the use of respirators, job rotation, personnel dosimetry and medical surveillance.
