摘要

Using steel slag and two types of (soft and hard) iron slags, ten samples were prepared. Different gamma radiation interaction parameters were computed theoretically and measured experimentally at different energies: 60 keV, 136 keV, 662 keV, 1173 keV and 1332 keV in low and medium energy range using narrow transmission geometry. It has been observed that shielding effectiveness of a sample is inversely proportional to Half Value Layer (HVL). The obtained results were compared with Pure Flyash and it was observed that slag is better aggregate than flyash in shielding radiation as well as in construction applications. The results have been presented in the form of tables and graphs with more useful conclusions.
