The main goal of this study was to determine the mass attenuation coefficient of paraffin wax and sodium chloride as tissue equivalent materials in medical imaging. In this study, a series of attenuation coefficient was evaluated for a mixture of paraffin wax and NaCl to be established as tissue equivalent materials. Five samples with difference paraffin-to-NaCl ratio were prepared. The attenuation coefficient of each sample was evaluated within energy range of 0.662 and 1.33 MeV. The measurements were performed with a NaI(Tl) detector for gamma spectrometry. The attenuation coefficient values obtained from this experiment were compared with mass attenuation coefficient obtained from the XCOM software and ICRU Report 44. The mass attenuation coefficients of the selected sample and human soft tissue are 0.151 cm2/g and 0.149 cm2/g respectively at energy of 150 keV. A sample with 25% of NaCl used was selected as an ideal tissue-equivalent material in this study.
