Neutron energy spectra and spectra of dose deposition in tissue‐equivalent material have been measured for neutron sources produced by 16‐, 22‐, 35‐, and 45.5‐MeV deuterons and 22.5‐, 35‐, 45‐, and 65.5‐MeV protons incident upon a thick beryllium target. Neutron spectra were measured using time‐of‐flight techniques and the dose distribution was measured using a 1/2 in. spherical “tissue‐equivalent” proportional counter filled with “tissue‐equivalent” gas.
