Shielding and activation study for proton medical accelerators

A preliminary study has reviewed much of the pertinent data on the required radiation shielding and radioactivation processes associated with the operation of a 70-250 MeV proton accelerator to be used for cancer therapy. As a result, a "tool kit" has been prepared for designing appropriate shielding and evaluating radiation hazards from activation around such accelerators, It includes general principles, a simple desktop computer program for preliminary facility design and the use of the LCS Monte Carlo program. The anticipated integration of the ORIHET program with LCS will provide detailed activation information. >
