Description:
Soil gas ^2^2^2Rn and ^2^2^0Rn concentrations were measured at 18 locations in the Karkonosze-Izera Block area in southwestern Poland. Measurements were carried out in surface air and at sampling depths of 10, 40 and 80cm. Surface air ^2^2^2Rn concentrations ranged from 4 to 2160Bqm^-^3 and ^2^2^0Rn ranged from 4 to 228Bqm^-^3. The concentrations for 10 and 40cm varied from 142Bqm^-^3 to 801kBqm^-^3 and 102Bqm^-^3 to 64kBqm^-^3 for ^2^2^2Rn and ^2^2^0Rn, respectively. At 80cm ^2^2^2Rn concentrations ranged from 94Bqm^-^3 to >1MBqm^-^3. The ^2^2^0Rn concentrations at 80cm varied from 45Bqm^-^3 to 48kBqm^-^3. The concentration versus depth profiles for ^2^2^2Rn differed for soils developed on fault zones, uranium deposits or both. Atmospheric air temperature and soil gas ^2^2^2Rn and ^2^2^0Rn were negatively correlated. At sampling sites with steep slopes, ^2^2^0Rn concentrations decreased with depth.
