Compared with conventional high energy X-ray radiotherapy, proton/carbon ion has obvious advantages because of its Bragg peak dose distribution. However, proton heavy ion facility has complex structure, high energy and various radiation types due to various nuclear reaction processes, the radiation protection safety brought by the operation of facilities has gradually attracted attention. Taking the proton/carbon ion radiotherapy facility of Shanghai Proton and Heavy Ion Center as an example, the author mainly analyzed the operation principle of proton/carbon ion treatment facility, the basis of radiation protection, analysis of key radiation source points, etc., so as to provide theoretical support and experience for radiation protection.
与传统高能X射线放疗相比，质子/碳离子因其布拉格峰剂量分布而具有明显优势。然而，由于各种核反应过程，质子重离子设施结构复杂、能量高且辐射类型多样，设施运行带来的辐射防护安全问题逐渐受到关注。以上海质子重离子中心的质子/碳离子放疗设施为例，作者主要分析了质子/碳离子治疗设施的运行原理、辐射防护基础、关键辐射源点分析等，以期为辐射防护提供理论支持和经验。
