The MCNP code was used to simulate neutron transmission and reflection from neutron sources of 14 MeV
5 MeV and 252Cf with a shielding body of different sizes in a room of different structures.The results show that both the size and the structure of the shielding body have quite big influence on the transmission of the neutron
and that the room structure and pit have quite big influence on the background reflection.The study provides a valuable reference for designing a neutron source room for experiment with a neutron source.
