MEASUREMENT OF RADIOACTIVITY IN SOME GRANITE SAMPLES BY USING (HPGE) DETECTOR

2017 International Journal of Latest Trends in Engineering and Technology  
In 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 238 U, 232 Th and 40 K 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

The radiation hazard indices [Ra eq D Ɣ , (AED) in , (AED) out , H in and H ex ] 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 QUICK RESPONSE CODE
