Opis:: In this study, 1010, 1040, 1050 and 1090 carbonized steels were investigated against gamma radioisotope sources on their gamma attenuation properties. Co-60, Cs-137 and Ir-192 gamma radioisotopes which are commonly used in industrial applications were used in the experiments. Half-value layers were carried out for studied carbonized steels against all studied gamma radioisotopes. In addition, the linear and mass attenuation coefficients were determined for each carbonized steels at different gamma radioisotope sources. The theoretical mass attenuation coefficients were calculated from XCOM computer code for all samples at specific energies of Co-60, Cs-137 and Ir-192 gamma sources. The theoretical and experimental results were compared with each other.

Opis:: Hexagonal boron nitride (h-BN) and hexagonal boron nitride-titanium diboride (h-BN-$TiB_2$) composites are advanced materials for high-tech applications. They were investigated against gamma radioisotope sources Cs-137 and Co-60 which have gamma peaks 0.662 MeV for Cs-137, and 1.17 and 1.33 MeV for Co-60. Materials have been produced at 1800C temperature in argon atmosphere without pressure during 2 h time. Linear and mass attenuation coefficients were calculated for the materials. Gamma transmission technique was used in the experiments. The experimental investigated mass attenuation coefficients of the materials for Cs-137 and Co-60 gamma radioisotope sources were compared with XCOM computer code. For h-BN-$TiB_2$ composites the ratio of $TiB_2$ in the composites is 55% by weight. So gamma attenuation effects of adding $TiB_2$ to h-BN were discussed. It could be said that adding $TiB_2$ to h-BN increases the linear gamma attenuation of the samples.
