Fast neutron fields are found in a wide variety of contexts, for example at accelerator and medical radiation facilities, around nuclear power plants, in airplanes in flight and space stations. These fields often vary widely with respect to both energy and intensity which complicates measurements of energy dependent fluence. Bonner sphere systems remain widely in use, although systems based on...

Instrumental Neutron Activation Analysis (INAA) is one of the most sensitive techniques to non-destructively determine the isotopic composition of a sample. The sensitivity of the technique is determined by the isotope of interest, intensity of the neutron source and neutron energy spectrum. In the case of thermal neutron irradiation with a nuclear reactor the minimum detection limits tend...
