Measurement of concentrations of the natural radio-activities and Cs-137 in soil samples in the Al-Baha region of Saudi Arabia

Abstract

Measurement of concentrations of naturally occurring radio nuclides together with Cs-137 deposited in soil have been carried out in the Al-Baha region of the Kingdom of Saudi Arabia. Soil samples collected from about fifty locations have been analyzed using high resolution hyper pure germanium spectrometers. Concentrations of the gamma emitting radio nuclides from naturally occurring uranium-radium and thorium series, Potassium-40, and Cesium-137 have been determined for the selected locations. Gamma-ray dose rates have been calculated from the measured concentrations of natural radioactivity in soil. © 2011 WIT Press.
