The data and methods which are available to carry out coupled neutron- photon transport calculations at neutron energies less than or equal to 50 MeV are discussed. The emphasis is on those problems involving the higher neutron energies (less than or equal to 15 to 20 MeV) and on those problems requiring charged-particle spectra produced by neutron-nucleus collisions. Much of this discussion, therefore, is centered about the code HETC which is capable of solving such problems. Calculated results on absorbed dose, LET spectra, cell- survival probabilities, OER's, and RBE's for several neutron spectra incident on a tissue-equivalent phantom are presented, and some comparisons between calculated results and experimental data are given. A few comparisons are also given for LET spectra, OER's, and RBE's for photons, neutrons, negatively charged pions, protons, and alpha particles incident on a tissue phantom. All of the cell-inactivation calculations were carried out using the model of Katz et al. and parameters appropriate to T-1 kidney cells. 16 fig, 8 tables, 64 refs. (auth)
