Abstract:
Rn is a (natural) radioactive gas which accumulates in closed spaces and produces lung cancer if it is inhaled, for that it represents a risk factor for the population’s health. As proven by worldwide recent studies, Rn contributes on an average of over 55% to the natural radiation exposure of the population, being able to reach in certain areas ontributions above 90%, cases when exposure to natural radiation is 5-6 times higher than the average exposure around the globe. The main source of indoor Rn is the ground and buildings’ substructure exhalation as well as emanation from the used construction materials.The measurement of the radon in the environment and buildings became during the last years an important field of radiation protection.The proposed method for radon measurement is based on the utilization of track detectors, CR-39, put into an alpha monitoring device. This paper presents results of the measurement in different places in Bucharest, using the CR-39 detectors.
