Moisture measurements of wood and sugar samples using neutron transmission technique

Moisture contents of sugar and shredded wood samples were measured using fast neutron transmission technique. Neutrons with 2.8 MeV energy were produced via D(d,n) reaction. The neutrons transmitted through the wood and sugar samples containing different moisture contents were detected by an NE213 scintillation detector. Monte Carlo simulations were carried out to calculate fast neutron detector counts as a function of water contents (wt%) of wood and sugar samples as well. The experimental results were compared with the results of Monte Carlo simulations. Within the experimental uncertainties, a good agreement has been achieved between the experimental results and the results of the Monte Carlo simulations.
