New Evaluation Method of Exposure to Radon Gas in Mining Environments

Physical and chemical agents in workplace environments can be hazardous for employees. Much of the exposure to ionizing radiation occur due presence radon workplace. Mining are more susceptible containing gas because it emanates from soil or rocks. Radon is known associated with lung cancer as a gaseous agent under normal conditions also radioactive. Since there little knowledge about Brazilian mining workplaces, this study aims measure occupational through proposed methodology verify its compliance international standards confirm potential risk concentration open-pit work was measured used basis comparison assess new evaluation method, which will consist laboratory evaluations samples taken same workplaces. The data were compared tests statistical correlation. results, reference values, tolerance limits, action levels, showed that radon, outdoor considered low employees’ health. application indicated field presented correlation each other, being an indication estimate risks preliminary way. Another important point fact observed measurements practical faster perform when evaluations. These facts bring future gains number performed evaluated environments.
