Residual Radiation Studies for Medium Energy Proton Accelerators

Residual radiation levels to be encountered in medium energy proton accelerators at high beam intensity are evaluated. Excitation function data were obtained for the production of the most probable radionuclides. A computer code that takes into account the change of cross sections as the beam penetrates the target material was used to compute residual radiation dose rates for carbon, aluminum, iron, and copper as functions of bombardment time and cooling time.
