Abstract
This study presents the results of indoor radon measurements collected during three survey campaigns, accumulating around 450 data taken in dwellings, public buildings, and workplaces. The first stage of the study focused on refining the database, which included only 220 measurements taken on the ground floors of dwellings. The information collected from the largest cities in twelve administrative areas of Albania showed that approximately 30% of indoor radon levels were above 100 Bq m−3, with only 4% exceeding the reference level of 300 Bq m−3. The average annual effective dose from indoor radon exposure was 4.9 ± 0.2 mSv y−1, while the geometric average was found to be 3.7 mSv y−1. Utilizing a 10 × 10 km grid, the data distribution covers roughly 20% of the area, according to a selection criterion for cells with more than 1,000 inhabitants. This map was used to assess the exposure of the population to indoor radon in Albania. Moreover, the results emphasized the importance of future studies to include the rural areas of Albania.
