Abstract: In recent years, the cancer treatment industry of medical proton/heavy ion accelerator in China has started to develop rapidly. Secondary radiation is produced when the accelerator is in operation, which endangers the radiation safety of the environment, the public and workers. Reliable radiation shielding design is a necessary guarantee for the radiation safety during the operation of the accelerator. In this paper, the general considerations for radiation shielding design of medical proton/heavy ion accelerator are briefly analyzed, and several common methods of shielding calculation are introduced with an example of calculation. The research in this paper has certain reference significance for the radiation shielding design of medical proton/heavy ion accelerator to be built in the future.

Key words: medical proton/heavy ion accelerator, shielding design, considerations, shielding calculation method
