Abstract
The major cause of elevated radon levels is the entry of soil generated radon as part of a larger flow of soil gas. A theoretical evaluation of the pressure differences causing these flows, and the resistance of different soil types and house foundations to the movement of soil gas suggested that the rate of radon entry could be predicted as a simple function of soil radium concentration and permeability. A new concept, the Radon Index Number, based on simple field measurements, is proposed as a guide to estimation of the annual average radon concentration in a standard house as a function of site soil parameters.Keywords
