Radioactivity in Minerals

Radiation Dose Calculation is based on the GRapi response. Since the GRapi response is scaled to the borehole geometry where the detector is centered in a borehole with a 3 inch standoff, the estimate is based on the GRapi response of common clay minerals. The government estimated exposure to terrestrial sources is 30 mRem/year.
