Abstract In an effort to quantify thegeogenic radon soil–gas potentialand appraise the use of radon tech-nique as a geological mapping toolin a crystalline basement rock terrain of Ile–Ife Nigeria, radon measure-ment concentration were made usinga radon detector instrument (EDARD-200) that measures radon isotopes by a scintillator cell coupled to a photo multiplier tube. The data were collected from soils derived from three different lithologic rock units. The observed values were the...
