Abstract
Measurement of the energy distribution of photo protons produced in deuterium loaded nuclear emulsions was used to determine the spectral distribution of a high energy X-ray beam. Details are given and experimental results compared with theory. Ionization chamber measurements of the angular distribution of X-rays from various targets are discussed. A rough calculation of the fast neutron dose relative to the dose from the X-ray beam is given using data obtained from the nuclear plates.
