Abstract
Certain nuclear reactions, such as (n, 2 n) reactions, inelastic scattering, and some (n, p) and (n, α) reactions, occur only when the neutrons have energies above a particular threshold energy. In many cases, these reactions lead to a radioactivity which can be measured after the irradiation. With the help of threshold detectors in the form of foils, we can use these reactions to determine the flux, the energy spectrum, or the dose of fast neutrons. Such foils are of special significance in measurements in bulk media (reactors); as a rule, the detectors considered in Chapter 3 are preferred in measurements in free neutron beams.
