Abstract Mass attenuation coefficient is an important physical quantity in X-ray analysis,and it is the most commonly used radiation characterization parameter at present. The hard X-ray ground calibration device can provide “single energy and narrow beam” experimental conditions for the measurement of mass attenuation coefficient,and is an ideal device for the study of mass attenuation coefficient. The mass attenuation coefficients of two medical module materials,Poly tetra fluoroethylene(PTFE) and Polymethyl methacrylate(PMMA),were measured in the energy range of (40~80) keV with a hard X-ray ground calibration device. The measured mass attenuation coefficients were compared with the reference values in NIST database. The relative deviation between experimental value and theoretical value was analyzed. The results show that the variation trend of the mass attenuation coefficient curves of the two materials is consistent with the theoretical value. The maximum relative deviation between the measured values of PTFE and the theoretical values is 5.274%@47keV,and the maximum relative deviation between the measured values of PMMA and the theoretical values is 6.303%@51keV.
