This test method covers a suitable means of obtaining the thermal neutron fluence rate, or fluence, in well moderated nuclear reactor environments where the use of cadmium, as a thermal neutron shield as described in Method E 262, is undesirable because of potential spectrum perturbations or of temperatures above the melting point of cadmium.
This test method describes a means of measuring a Westcott neutron
fluence rate (Note 1) by
activation of cobalt- and silver-foil monitors (See Terminology E
NOTE 1 - Westcott fluence rate = v0∫∞0n(v)dv.
The values stated in SI units are to be regarded as the standard.
