The development of technology increases the
environmental pollution and radiological effects. In the present work, the radiation
effects were determined experimentally, in the high strength lightweight
concrete according to  water /cement ratio . Also, the mass attenuation coefficients of the high strength lightweight concrete samples which producing with perlite aggregate were determined. The measurements were performed using a high-purity germanium detector. Ten different gamma rays energies were used. It is observed that the mass attenuation coefficients of the concrete samples are decreasing with the increasing photon energies. The concrete obtained with perlite aggregate can be used for protect from the radiation.water /cement ratio .

Teknolojinin gelişimi
ile çevre kirliliği ve radyolojik etkiler artmıştır. Bu çalışmada, ham perlite
agregası kullanılarak üretilen yüksek dayanımlı hafif betonda su-çimento oranının
radyasyona etkisi deneysel olarak belirlenmiştir. Ayrıca, beton numunelerin
perlit agregalı kütle zayıflama katsayıları belirlenmiştir. Ölçümler, yüksek
saflıkta bir germanyum detektörü kullanılarak gerçekleştirilmiştir. Farklı gama
ışın enerjileri kullanılarak beton örneklerinin kütle soğurma katsayılarının
artan foton enerjileri ile azaldığı gözlenmiştir. Perlit agregası ile elde
edilen betonun radyasyondan korunmak için kullanılabilir olduğu ortaya çıkmıştır.
