Exposure of school children to alpha particles
Background: A substantial part of the public’s natural radiation dose is due to the inhalation of radon gas. Most of the exposure occurs indoors where the airborne concentration of radon and its decay products is usually higher than outdoors. Materials and Methods: Radon activity concentration has been measured twice in 50 classrooms in 5 levels (10 each) during summer and winter using solid-st...
