The information below is taken from governmental agencies and official national organizations that regulate radon and air quality . Most of the measures were taken in periods of one year or more .
While most of the countries stick to values suggested by international organizations , like the WHO , each country makes exceptions based on local soil conditions and other industry regulations .
Most countries set different action levels for homes and offices , the latter being higher than residential ones . The links provided here contain information about action levels for homes ;

Americas
Although the effects of radon were first documented as early as 1530 in Europe , the famous “ Watras incident ” in the U . S in 1984 put radiation regulations on the map . Since then many studies have been carried out to find a correlation between lung cancer and radon exposure .
That ’ s why recommended values in North America are lower than those recommended by the WHO , and workplace regulations – especially regarding power plant and mine workers –
are stricter and more comprehensive than in Europe .
