| Abstract: | The scattering characteristics of high γ- ray reference radiation field is stimulated by the Monte Carlo code MCNP to confirm the dose rate and the energy spectrum distribution of the experimental space. Careful analysis of the scattering of shielding wall and in-beam scatterer from multiple perspectives provides reference for the experimental application and shield design of Co- 60 radiation field of Calibration laboratory. |
