Abstract
A new method for monitoring radon concentrations in air, which is based on measuring the γ activity of aerosol filters, through which air is uninterruptedly circulated, is described. In this case, the equilibrium concentration of decay products on the filter is proportional to the radon concentration in air. The use of a large (20 (diameter) - 20 cm) NaI(Tl) crystal with a well for realizing a 4π-geometry ensures a 15-to 20% error of the method.
