Radon in soil gas in Kosovo

The levels (Bq kg−1) of naturally occurring radionuclides and levels (kBq m−3) of radon in soil gas obtained at a depth 0.8 m of soil were: 21-53 for 226Ra, 22-160 for 238U and 0.295-32 for 222Rn. With respect to lithology, the highest value for 238U and 226Ra were found in limestone and the highest value for 222Rn was found in metamorphic rocks. In addition, the results showed seasonal variations of the measured soil gas radon concentrations with maximum concentration in the spring months.
