Representativeness of the radon database (RAME)

Aim of the study

There are over 100 000 radon measurements in STUK´s database. The large data set enables detailed studies of the effect of building characteristics, radon prevention, building site circumstances, weather conditions etc. on indoor radon concentration. The data set is, however, not representative, as people living in high radon areas are more likely to carry out the indoor radon measurement.

Implementation

Representative national radon parameters (average, median, fraction exceeding 200 and 400 Bq/m3) are determined by calculating the values for 1x1 km cells and weighting the cell values with the building density of each cell. National parameters are compared to the results of the Radon Surveys 1990–1991 and 2006–2007. The effect of the most important building characteristics (soil type at the building site, foundation type, ventilation type) on radon concentration is also studied.

Dissemination and exploitation of the results

The results are published in an original research paper.
