A set of Kinetic Energy Released in Matter (KERMA) values for H, C, N, and O are presented based upon two sets of computer calculations. One set includes neutron energies from 20 to 80 MeV and uses the Intranuclear Cascade plus Evaporation (ICE) models. The second set includes neutron energies from 10 to 20 MeV and uses the Evaluated Nuclear Data File (ENDF/B-V) for particle species and numbers, with a modified Evaporation model for the particle energies. The 10- to 20-MeV ENDF calculations, which show good agreement with values calculated by Caswell and Coyne (1), were performed to allow normalization of the 20- to 80-MeV ICE calculations at 20 MeV. Values for ICRU muscle tissue and Shonka A-150 plastic are also included.
