【Abstract】 The irradiator’s calculation method of shielding parameters and reserving multiple radioactive source’s capability were established by Monte Carlo code MCNP/4B simulation. The shielding thickness of multiple materials assembled and capability of storing multiple radioactive source were obtained, which optimized design structure. The results and computation model were verification by experiment data, which obtain reference to developing and using of the device.更多还原
