Long-term integrated radon measurements (alpha-track) were carried out in two housing blocks in Vienna diagonally across from each other. The arithmetic mean was 41 becquerels/cubic metre (= Bq/m3), concentrations ranging from 157 to 9 Bq/m3. The largest variation found within one block came up to a factor of 13, within one house to a factor of 8 and within one floor of one and the same house to a factor of 4. The measurements gave the opportunity to practice risk communication with the residents of the two housing blocks.
