Abstract

An attempt has been made to experimentally investigate the optimum thickness in order to measure mass attenuation coefficients for some Sn–Pb alloy systems at incident photon energies 122, 511 and 662keV. The Sn–Pb alloys were synthesized with different compositions and different thicknesses using melt-quench technique and cast iron mould. The physical parameters such as mass, thickness, density have been measured for all the prepared alloys. Further, the transmitted photon spectra of Cs-137, Co-57 and Na-22 radioactive isotopes were recorded using GAMMARAD5 (scintillator detector) of dimensions 76mm×76mm with and without inserting different alloy samples between the radioactive isotopes and detector. The experimental results so obtained were compared with the theoretical ones of WinXCom and optimum thickness for measuring mass attenuation coefficients for the selected alloys has been recommended.

摘要

已尝试通过实验研究最佳厚度，以便测量某些Sn-Pb合金系统在入射光子能量122、511和110时的质量衰减系数。 662 keV。利用熔融淬火技术和铸铁模具合成了具有不同成分和不同厚度的Sn-Pb合金。已为所有制备的合金测量了物理参数，例如质量，厚度，密度。此外，使用尺寸为76 mm × 76 mm，有或没有在放射性同位素和检测器之间插入不同的合金样品。将这样获得的实验结果与WinXCom的理论结果进行比较，并推荐了用于测量所选合金的质量衰减系数的最佳厚度。
