Indoor 222Rn concentrations in Central Asturias.
A survey of the 222Rn concentrations in 106 homes in the four main towns of the Central Asturias region was carried out over three years. A total of 1,014 measurements was obtained using passive radon charcoal canisters. The 222Rn concentrations fit a log-normal distribution law, with a geometric mean of 23 Bq m(-3). There is a marked difference between the 222Rn concentration for the ground inhabited floors and first floors. For the other floors, the 222Rn concentrations remain practically constant. The 222Rn concentrations are lower in summer than in winter time. The annual equivalent dose for the general public due to the inhalation of 222Rn is equal to 0.81 mSv (81 mrem).
