Soil gas radon and soil permeability assessment: Mapping radon risk areas in Perak State, Malaysia.

In this study geogenic radon potential (GRP) mapping was carried out on the bases of field radon in soil gas concentration and soil gas permeability measurements by considering the corresponding geological formations. The spatial pattern of soil gas radon concentration, soil permeability, and GRP an...
