Calculation of Dosimetry Parameters for Fast Neutron Radiotherapy.

摘要

A computer simulation of the interactions of 50MeV d exp +on Be and 42MeV p exp +on Be neutron spectra with ICRU muscle tissue and Shonka A-150tissue equivalent plastic was performed to allow computation of the charged particle spectra that result. Nuclear data were obtained from the Evaluated Nuclear Data File (ENDF) whenever possible and from the Intranuclear Cascade and Evaporation models otherwise. The dosimetry parameters calculated are:the kerma ratio, K/sub A-150//K/sub tissue/;the energy required to form an ion pair, W;and the stopping power ratio, S/sub g//sup W/. (ERA citation 03:056158)
