The method covers procedures for determining the energy-fluence spectra of neutron sources used in radiation-hardness testing of electronic semiconductor devices. The type of sources specifically covered by this method are prompt critical assemblies, such as Godiva- to Triga-type reactors, used in either a steady-state or fast-pulse mode. The method is not applicable to power reactors. The method covers the measurement of the gamma-ray emission rates from a set of neutron threshold activation foils and the calculation of the absolute specific activities of these foils. The principal measurement technique is high-resolution gamma-ray spectrometry. The results are used in the calculation of the energy-fluence spectrum of the neutron source. (JMT)
