To shield people from dangerous gamma radiation, it is imperative to fabricate inexpensive and environmentally friendly materials. In the present work, suitability of concrete with various % concentrations of ceramics as gamma-ray shielding material has been studied. In this regard, concrete mixture using M-sand and cement with ceramic as filler in different concentrations has been prepared. The mass attenuation coefficients of the prepared samples were measured for different concentrations of ceramics such as 15, 30, 45 and 60%. The mass attenuation coefficients, half value layer (HVL) and tenth vale layer (TVL) of the prepared samples were determined using gamma-ray spectrometer with NaI(Tl) detector at 511, 661.6, 1173, 1332 keV gamma energies. Experimentally obtained mass attenuation coefficients varied from 0.080 to 0.090, 0.074 to 0.086, 0.056 to 0.072 and 0.054 to 0.055 cm2 g-1 at 511, 662, 1173 and 1332 keV, respectively. Therefore concrete mixture with ceramics filler could be a promising shielding material than the bare concrete.
为了保护人们免受危险的伽马辐射，制造廉价且环保的材料是当务之急。在本工作中，研究了不同浓度陶瓷的混凝土作为伽马射线屏蔽材料的适用性。为此，使用 M 砂和水泥制备了含有陶瓷作为填料的不同浓度的混凝土混合物。测量了不同陶瓷浓度（如 15%、30%、45%和 60%）的制备样品的质量衰减系数。使用 511、661.6、1173 和 1332keV 伽马能的 NaI(Tl)探测器的伽马能谱仪，确定了制备样品的质量衰减系数、半价层（HVL）和十分之一价层（TVL）。实验获得的质量衰减系数在 511、662、1173 和 1332keV 时分别为 0.080 至 0.090、0.074 至 0.086、0.056 至 0.072 和 0.054 至 0.055cm2 g-1。因此，含有陶瓷填料的混凝土混合物可能是一种比裸混凝土更有前途的屏蔽材料。
