1.1 This test method covers a general procedure for the measurement of the fast-neutron fluence rate produced by neutron generators utilizing the H(d,n) He reaction. Neutrons so produced are usually referred to as 14-MeV neutrons, but range in energy depending on a number of factors.
1.2 This test method uses the following threshold activation reactions: in aluminum, 27 Al(n,[alpha]) Na and 27 Al(n,p) Mg; in nickel, Ni(n,p) Co and Ni(n,2n) Ni; and in copper, Cu(n,2n) Cu and Cu(n,2n) Cu. The neutron fluence rate is determined from induced foil activities (as measured by gamma spectrometry) and reaction cross-section data.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
