Abstract:
Neutron radiation can be used to measure moisture in mineral matter. The author has worked with neutron mois ture gauge. This meter has source of fast (MeV) neutrons. The gauge detects thermal or epithermal down-slowed neutrons. For modelling Monte Carlo (MC) calculation has been done. The process has 2 MC-paths. One from the source down, and the other from detector up. They meet at a certain energy E. The first slowing-down density and second detection probably are multiplied and integrated to get the counting rate (the result of measurement). The first result of modelling is presented. Then spherical symmetry assumption is applied. It seems that cylinder assumptions should be used.
