Catalogue with neutron spectra based on reference spectrometry

In total, seventeen different places were investigated: nuclear energy production (reactors), transport of the nuclear fuel (transport casks), fresh MOX fuel rods manufacturing and a site handling nuclear material. A catalogue with these spectra was published in the open literature.

The measurements revealed significant differences in the neutron energy distributions at the workplaces. While all distributions exhibit similar structures - a thermal peak, a rather flat intermediate energy region and a peak from fast neutrons with a maximum between 100 keV and 1 MeV - the contributions of these neutrons to the fluence varies significantly.
