| Abstract: | In order to research on the correlation of gamma energy spectrum and absorbing medium,based on the method of Monte Carlo,MCNP5 was used to simulate the changes of gamma energy spectrum after gamma photons for 1.46 MeV eitted by 40K through absorbing mediums on 12C,27Al,32S,56Fe and 65Zn,and summarizes the relationship between the characteristics of gamma energy spectrum and the atomic number,the density and thickness of the materials.The results showed that the atomic number of absorbing medium has great in... |
