Abstract: Radon concentration measurements have been carried out in the selected dwelling houses in Rahovec city, using continuous radon monitor Model CRM-510. This study has covered a region of Kosovo which has not investigated before for radon concentration and the scope of this study is to contribute on Kosovo Radon Map, which is not still completed. Also, has been analysed the impact of age of buildings, type of walls and windows on selected dwelling houses chosen for radon concentration measurements. The average radon concentration on living room has been found to vary from 103.7 19.8 Bq/m3 to 207.1 48.1 Bq/m3. The annual effective dose is found to be lower than action levels of annual effective dose recommended by International Commission of Radiation Protection (ICRP).
