Abstract
The variation in intensity of 1.78Â MeV silicon, 6.13Â MeV oxygen, and 2.22Â MeV hydrogen prompt gamma rays from soil samples due to the addition of 5.1, 7.4, 9.7, 11.9 and 14.0Â wt% water was studied for 14Â MeV incident neutron beams utilizing a LaBr3:Ce gamma ray detector. The intensities of 1.78Â MeV and 6.13Â MeV gamma rays from silicon and oxygen, respectively, decreased with increasing sample moisture. The intensity of 2.22Â MeV hydrogen gamma rays increases with moisture. The decrease in intensity of silicon and oxygen gamma rays with moisture concentration indicates a loss of 14Â MeV neutron flux, while the increase in intensity of 2.22Â MeV gamma rays with moisture indicates an increase in thermal neutron flux due to increasing concentration of moisture. The experimental intensities of silicon, oxygen and hydrogen prompt gamma rays, measured as a function of moisture concentration in the soil samples, are in good agreement with the theoretical results obtained through Monte Carlo calculations.
