Alternative methods for assessing the protective effect of liners against radon emissions, with the focus on the radon decay product Pb-210. The so-called 'lead track' was used, i.e. the difference of the specific activities of Pb-210 and Ra-226. With a half-life of 22.3 years, Pb-210 is well suited for assessing long-term effects of radon transport by measuring its specific activity in soil samples. Especially measurements of the depth-dependent Pb-210 concentration profiles resp. the lead track in soils and liners provided information on exhalation of radon or radon concentrations in soil air, which reflect the transport patterns over periods of more than 30 years.
