A preliminary indoor radon survey in Greece based on about 250 passive detectors, to test the technique and the statistics, is presented.
The majority of the detectors were placed in schoolrooms and dwellings for a year.
The measurements conceming the northem part of Greece indicate a higher radon concentration than the rest of the country.
The radon concentrations are well fitted to the theoretically expected log-normal distribution.
In the attached map three concentration categories are marked : (0-99 Bq. m-3,100-200 Bq. m-3 and>200 Bq. m-3).
Due to the small sample of detectors, one should not interpret this map as characterising whole geographic areas, but simply indicating the radon concentrations at the particular sites.
In order to complete a national radon survey, a much more dense sample is needed.
