Risque radiologique dans les mines de charbon en Pologne

Abstract

The conditions of exploitation of coal in underground mines in Poland are raising risks of exposure to ionizing radiation, the sources being the radium present in mine waters and sediments and short-lived radon daughters present in air. The miners'colfective annual radiation dose (540 man-sievert) is higher than the collective dose in nuclear activities in Poland (137 man-sievert). The system of control and prevention of risk was introduced in these mines in 1989.
