| Abstract: | The three-dimensional dose distribution in polystyrene were calculated by the simulation based on the user code DOSRZnrc of the latest version of the EGSnrc a new EGS4 version EGSnrcMP Monte Carlo code system with 4MeV initial electron energy.And the depth dose distribution in polystyrene and H2O were calculated with 2.5-4MeV initial electron energy.And the effects of different electron beam sizes on absorbed dose were calculated too.The dose was given by absolute dose（Gy·cm^2）.The calculation uncertainty was controlled within 1%.This kind of work proposes a useful theoretical tool for optimizing technology of electron radiation processing. |
