Measurement of natural radioactivity in some types of cement samples by using (HPGe) detector

Abstract

In the present work, we have measured specific activity concentrations in ten cement samples from different origins by using high purity germanium (HPGe) detector. The results have shown that, the specific activity, for 238U was ranged from (22.23±4.7 Bq/kg) in Turkyi origin to (9.39±3 Bq/kg) in Iraq (Najif) origin, for 232Th was ranged from (24.56±4.9 Bq/kg) in Turkyi origin to (8.98±2.9 Bq/kg) in Iraq (Najif) origin, for 40K was ranged from (317.81±17.8 Bq/kg) in Turkyi origin to (67.34±8.2 Bq/kg) in Iraq (Kabisa) origin. The study shows the cement samples do not pose any significant source of radiation hazard and are safe for use in the construction of dwellings.
