摘要

Some therapeutic proton synchrotron accelerators will be built for cancer treatment in China. The radiation produced by proton must be carefully evaluated and shielded for occupational disease hazard assessment and environmental impact assessment. Adopting the FLUKA code, a therapeutic room model, a synchrotron hall model and a high energy transport line tunnel model are constructed to get the ambient dose equivalent rate distributions. The ambient dose equivalent rates are also calculated with an empirical formula in some regions. The results calculated by the two ways are consistent with each other. The advantages and disadvantages of the two methods have been analyzed. The ambient dose equivalent rates are no more than 2.5 μSv/h at 30 cm beyond the shielding wall and the maze door. The dose rates are <25 μSv/h at 30 cm beyond the roof of the therapeutic room. These results comply with the National Occupational Health Standard requirements.
