Medium energy neutron and proton nuclear data for therapy

The range and status of nuclear data on the interaction of medium-energy neutrons and protons with biomedical materials are discussed. Microscopic data (cross sections) include results of experimental measurements, indices and compilations of such data, and evaluated data. Experimental data, while usually available only in partial ranges of interest, are essential for validating and normalizing nuclear models used to produce comprehensive evaluated data libraries. Integral measurements of radiation transport such as depth-dose curves and of KERMA coefficients test the data and their application in transport calculations. (orig.)
