| Abstract:: |
| Objective To use Monte Carlo method to build a shielding calculation model for the proton and heavy ion treatment room, and to provide a reliable calculation method for shielding design.Methods A Monte Carlo-based FLUKA code was adopted to build the shielding calculation model for the proton and heavy ion treatment room, and to simulate the radiation field distribution in the proton and heavy ion treatment room. The calculation model was verified through the radiation detection around the proton and heavy ions treatment room. Results The FLUKA code-based simulation results were consistent with the radiation detection. Conclusions The shielding calculation model based on FLUKA code can simulate the radiation field from proton and heavy ions. Among the secondary particles, secondary neutrons are the dominant component and the main concern of accelerator shielding design. In shielding calculation, the emphasis should be put on both beam intensity and energy. |
