The radiation hardness parameter is evaluated for thirteen displacement kerma factors and twelve incident neutron energy-fluence spectral distributions. The integrals are performed interactively using an adaptive recursive Simpson integration technique in Turbo-Pascal which allows for any mixture of analytic and/or multigroup displacement kerma factors and spectral distributions. The radiation hardness parameter determined from a recent NJOY evaluation is compared with other known evaluations. The simulation fidelity, which depends on the ratio of hardness parameters in the operational environment to that for the simulation environment, is evaluated and compared for these spectra and models. Except for the 14 MeV spectra, the simulation fidelity of most models agree with the NJOY to within 10%. 15 refs., 6 tabs.
