摘要：
The mass attenuation coefficients, mu/rho of some thermoluminescent dosimetric materials with potential applications as personnel dosimeters, have been investigated using Geant4 simulation toolkit. Appreciable variations are noted for the mu/rho values by changing the photon energy and chemical compositions. The Geant4 toolkit simulation results of mu/rho are compared with experimental data wherever possible. Comparisons are also made with predictions from the XCOM program in the energy region from I keV to 100 GeV. Good agreement among Geant4 toolkit simulation, XCOM program and experimental data indicate that the Geant4 toolkit may be employed to make calculations on the mu/rho values of various dosimetric materials. The results indicate that this process can be followed to determine the interaction of photon with the several energies in different materials. (C) 2014 Elsevier Ltd. All rights reserved.
