Nuclear data for fast neutron and proton therapy

An International Commission on Radiation Units and Measurements (ICRU) report describing nuclear data that are needed in fast neutron and proton radiotherapy studies and for radiation protection is in preparation. The nuclear cross sections are evaluated using a combination of measured data and nuclear model calculations. The report reviews measurements that have determined cross sections and kerma coefficients, but since there are only a limited number of experimental data sets for biologically-important target elements, theoretical predictions are needed to supplement these data. The evaluated cross sections and kerma coefficients are tabulated in the report for neutron and proton-induced reactions on H, C, N, O, Al, Si, P, Ca, Fe, Cu, W and Pb
