Bibliographic information Finnish Institute of Occupational Health, FIOH-Bookstore, Topeliuksenkatu 41 a A, 00250 Helsinki, Finland, 2009. 95p. Illus. Bibl.ref. Price: EUR 22.95.
Abstract This report studied the main factors affecting indoor radon concentrations, namely construction of the building's foundation, the type of ventilation used and pressure differences between indoor and outdoor air. Construction on hillsides, the use of mechanical exhaust ventilation and location in radon-prone areas of Finland increase the indoor radon concentration. The pressure differences and ventilation rates did not affect the indoor radon concentration statistically significantly. In most of the buildings investigated, radon emitted from construction materials proved to be only a minor source of radon. The study demonstrated that the need for radon surveillance and mitigation is of utmost importance especially in workplaces in the radon-prone areas of Finland. Mitigation is even more important if the workers live in a similar or higher risk area in which their workplaces are located.
