Natural sources can contribute with significant radiation quantities toward the total radiation exposure that humans receive. The majority of this natural radiation is harmless to humans in the ambient environment. However, radon, a large component of the natural radiation which humans are exposed to, can pose a threat to the workers health when radon gas accumulates in poorly ventilated occupational settings. Radon is the most hazardous natural source of radiation. Even if it is an inert gas, having no color, taste, smell, it has a number of other extremely dangerous properties for the human body. The risk of radiation within underground coal mines refers to natural radionuclides, which are included in coal and surrounding rocks. The Rn-222 radon is a result of Ra-226 radius’s disintegration, it can remain stuck in the rock and it can diffuse in the working place atmosphere as aerosol. Through the data and information provided, the aim of this paper is to present an analysis of the evaluation possibilities of risk exposure associated with the existence of radon in underground coal mining, as well as an estimation of workers’ annual exposure. Based on the results highlighted, a better understanding and optimized mitigation measures can be further developed in practice.

Keywords: radon, radionuclides, radiation, exposure, risk.
