Formation of the Neutron Energy Spectrum Near the Target of a Portable NG-24M Neutron Generator

  • IONIZING RADIATION MEASUREMENTS
  • Published:
Measurement Techniques Aims and scope

The spectrum of neutrons near the target of a portable NG-24M neutron generator is measured by the neutron activation method. The recovered neutron spectrum is represented analytically as a superposition of known physically substantiated spectra.
