Indoor Radon Testing, Effective Dose and Mitigation Measures in a Residential House of a Mining Area.

This study presents the results of continuous indoor radon measurements in a test-house in the vicinity of the "Trepča" mine, near the town of Kosovska Mitrovica. Annual measurements were performed using the detector, Airthings Corentium Home, in the bedroom of an old residential building. A high estimated annual effective dose from radon (33 mSv) was calculated using the last ICRP dose conversion factor and is discussed here regarding the previously recommended ones. There are significant indications concerning the health hazard. Several measures are proposed and serve as a technical solution including other effective, low-cost radon mitigation procedures in order to reduce radon levels. The effectiveness of the applied measures resulted in a 44% reduction in radon concentration. [ABSTRACT FROM AUTHOR]
