Determination of mass attenuation coefficients of γ-ray in bone tissue equivalent material
In this paper, γ‑ray with varied energies of 60, 186, 242, 295, 352, 609, 662 keV, emitted from radioactive sources 124Am, 226Ra, 137Cs, are used to determinate the attenuation coefficient for eight samples of different composition prepared from organic compounds (epoxy) and sodium chloride. Measurements are conducted using a γ-ray spectrometer connected to sodium iodide detector (NaI(Tl)). The results are compared with the ICRU-44 report values. It is found that there is good agreement between the obtained results and results from ICRU-44, and the difference is less than 3%. In comparison to ICRU-44, it is confirmed that the materials used in this study, are good alternatives for dosimetry and potentially for tissues to make tissue phantoms for biological tissues under study.
