A first step in mapping indoor radon concentration in Kosovo and Metohija was taken by carrying out 153 measurements in residential houses. About 21% of the territory of these areas was covered by mapping. Dosimeters with CR-39 detectors were used to measure indoor Rn-222 concentration, all deployed on the ground floor of typical houses. The arithmetic mean (AM) over AMs within 10 km x 10 km grid cells is 202 Bqm(-3) and geometric mean (GM) is 148 Bqm(-3). The data for mapping are arranged according to recommendations made by the Joint Research Centre (JRC) of the European Commission (EC) in 2006. This paper presents the status of the survey of natural radioactivity in Kosovo and Metohija.1st East European Radon Symposium (FERAS), Sep 02-05, 2012, Cluj Napoca, Romani
