thermal neutron

noun

A neutron in thermal equilibrium with its surroundings.It is usually the case in neutron activation analysis that both unknown samples and standard materials containing known elemental concentrations are irradiated with thermal neutrons in a nuclear reactor....

The normalizing factor for exposure to alpha particles is 20, for thermal neutrons is two, for fast neutrons is 10, for protons is 10, and for beta particles is one.
In the thermal type of power reactor, the neutrons are slowed to become thermal neutrons, and the number of fissile nuclei is less than the number consumed in fission; the ‘breeding’ process is therefore not self-supporting.
