Moisture effect in prompt gamma measurements from soil samples
The variation in intensity of 1.78MeV silicon, 6.13MeV oxygen, and 2.22MeV hydrogen prompt gamma rays from soil samples due to the addition of 5.1, 7.4, 9.7, 11.9 and 14.0wt% water was studied for 14MeV incident neutron beams utilizing a LaBr3:Ce gamma ray detector. The intensities of 1.78MeV and 6....

| description | The variation in intensity of 1.78MeV silicon, 6.13MeV oxygen, and 2.22MeV hydrogen prompt gamma rays from soil samples due to the addition of 5.1, 7.4, 9.7, 11.9 and 14.0wt% water was studied for 14MeV incident neutron beams utilizing a LaBr3:Ce gamma ray detector. The intensities of 1.78MeV and 6.13MeV gamma rays from silicon and oxygen, respectively, decreased with increasing sample moisture. The intensity of 2.22MeV hydrogen gamma rays increases with moisture. The decrease in intensity of silicon and oxygen gamma rays with moisture concentration indicates a loss of 14MeV neutron flux, while the increase in intensity of 2.22MeV 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.
•Silicon, hydrogen and oxygen prompt gamma ray measurements from soil samples containing 0–14wt% moisture (water) concentration.•14MeV neutrons based PGNAA setup with LaBr3:Ce gamma ray detector.•With increasing moisture concentration decreasing intensity of Si and O prompt gamma rays.•With increasing moisture concentration increasing intensity of H prompt gamma rays.•Monte Carlo calculation of Si, H and O prompt gamma ray intensities from soil samples.•Good agreement between the experimental and calculated results. |
