MEASUREMENT OF NATURAL RADIOACTIVITY IN BUILDING MATERIALS SAMPLES BY USING (HPGe) SYSTEM
AbstractIn the present work, we have measured natural radioactivity in twelve building materials samples for four kinds (Brick, cement, gypsum and sand) obtained from some Iraqi governorates by using High Purity Germanium (HPGe) radiation detectors system. The results of measurements have shown that the average values specific activity concentrations for 238U, 232Th and 40K which were equal to (24.236 ± 4.4 Bq/kg), (26.394 ± 4.0 Bq/kg) and (174.888 ± 29.1 Bq/kg), respectively., which were lesser than the corresponding recommended global values reported by (UNSCEAR, 2000) publication. The radiation hazard indices [Raeq DƔ, (AED)in, (AED)out, Hin and Hex] were also studied. The obtained results were also found to be lesser than the allowed limits given by (UNSCEAR, 2000). Thus, all results obtained in the present work have shown no significant radiological hazard when the studied building materials is used for construction of buildings.
