DETERMINATION OF NATURAL RADIOACTIVITY OF SOME SELECTED ECONOMIC MINERALS FROM QUARRY SITES IN IGARRA AREA, EDO STATE, NIGERIA
ABSTRACT Activity concentrations of radionuclides in rocks and minerals are of vital importance in geosciences and health physics especially that primordial radionuclides constitute the main source of radiation exposure risks externally in soil, rocks and minerals. In this study, samples of four (4) economic minerals, namely dolomite, feldspar, limestone and calcite, were collected from quarry sites in Igarra area, Edo State, Nigeria and analysed using gamma ray spectrometric technique.
