Release of 222Rn from some soils

Dueñas, C.; Fernández, M. C.; Carretero, J.; Liger, E.; Pérez, M.

Measurements have been made of 222Rn release from diverse soils in the region surrounding Málaga, Spain. These flux measurements were carried out by two methods. A direct method using a static chamber technique and another indirect method obtained from concentration profile measurements of 222Rn in the soil air. The effects of meteorological variables and other parameters on 222Rn flux were studied. The factors that most affected the instantaneous value of 222Rn release were humidity and soil thermal gradient. The directly measured 222Rn fluxes at investigated sites are higher than 222Rn fluxes derived by the indirect method.
