Abstract

The results of experimental studies of the neutron field characteristics with an energy of 14.7 MeV created by the portable neutron generator NG-14 are presented. The measurements were made using a fast neutron radiometer based on a diamond detector. The neutron beam from the neutron generator’s target passed through a massive collimator made of steel. Analysis of the amplitude spectra of the diamond detector, caused by the registration of fast neutrons, made it possible to determine the following characteristics of the neutron field: the flux density of direct neutrons, the flux density of neutrons scattered in the collimator, and the energy spectrum of neutron radiation. Based on the obtained energy spectra, the kerma of neutron radiation in the water phantom and the dose rate of scattered neutrons behind the collimator with an energy higher than 0.5 MeV were calculated.
