title: Measurement of 210Po atoms content in glass as an indicator of long-term exposure to radon.
abstract: Measurements of exposure to radon are performed using numerous research methods which register either temporary or periodic radon concentrations. The method presented below allows for the estimation of average radon concentration in the past. This is possible due to indirect measurement of the contents of 210Pb embedded in glass structure. The half-life of 210Pb is about 22 years. A number of exposures of window glass to radon have been carried out in laboratory conditions (radon chamber) and the obtained results were used to calculate the coefficient that renders it possible to define global indoor exposure to radon. The registration was made using a track detector CR-39, which records alpha particles resulting from the disintegration of 210Po, one of 222Rn decay products.
