First step towards the geographical distribution of indoor radon in dwellings in Albania

The realisation of the geographical distribution of the indoor radon concentrations in dwellings represents a valuable tool necessary for assessing the public exposure. In this work are reported the results of the indoor radon obtained in the first stage of the survey involving 247 measurements. From the preliminary information on ~10 % of the territory, covering the biggest cities in Albania results on indoor radon concentrations ranging from 14 to 1238 Bq m-3 with an arithmetic mean of 120±67 Bq m-3. The population-weighted average indoor radon concentration was calculated to be 101 Bq m-3. The adopted survey strategy highlighted the necessity for the future stages to spread the measurements in order to cover the entire territory of Albania, instead of remaining focused only on the demographic criteria.
