Abstract

A method for simulating the cosmic-ray-induced neutron background at ground level has been developed. This method was used to obtain the expected pulse height distributions, net neutron rates, and angular distribution using EJ-309 liquid scintillators, and has been validated using outdoor measurements. The simulations were carried out using the Monte Carlo transport code MCNPX-PoliMi combined with the source subroutine CRY. The absolute count rates for neutrons were then obtained from the simulations using an empirical scaling formula from literature. Preliminary measurements of the angular distribution of background neutrons were done using a collimated EJ-309 liquid scintillator, showing fair agreement with simulations.
