Description

The Fermi age and diffusion theory modeling is applied to study detection mechanism of a subsurface neutron soil moisture meter with a Li-glass scintillation probe. It is found that when the distance between the scintillator and the source is fixed, the thermal neutron counts given by the detector are mainly due to the interaction of neutrons with the medium confined by the side solid-angle of the scintillator with the latter as the centre
