Description

Using NM2 neutron monitor measure the curve of the radiation dose of roof that caused 241Am-Be neutron source located in the pool with the height of liquid level, combining the verification by MCNP simulation, so as to determine the size and position of the neutron source. On this basis, MCNP simulation is used to construct the energy and flux distribution of the neutron field generated by the source at a specific location, so as to provide the basis for subsequent experiments.
