□四川日报全媒体记者 文露敏项上的力量沿着厚实的辐射屏蔽墙体，走过"S"形的迷道，中广 核"和质"质子治疗系统的核心部件之一——"230MeV（兆电子伏）回旋加速器"便出现在眼前。这 是一台直径约4.3米、高2米、重220吨的"大宝贝"。由它发出的"光"，能够实现对肿瘤的精准狙 击。"基地投运一年，目前已完成3台230MeV回旋加速器的生产。"中广核医疗科技（绵阳）有限 公司总经理周川介绍。他口中的基地，是国内首座商用多室质子治疗系统生产基地，位于中国 （绵阳）科技城核医疗健康产业园内。引进再创新 实现技术反向输出"它可以说是肿瘤放射治 疗'皇冠上的明珠'。"从事放疗装备行业多年的周川，这样描述质子治疗的前沿地位。不同于传统 放疗的X射线，质子射线在刚进入人体时剂量很低，到达肿瘤位置后立即大量释放能量，一旦穿 过病灶又悄然消失，就像一场精准爆破，副作用更小，能更好地保护人体正常组织。然而，我国 在质子治疗上起步稍晚。为尽快实现与国际质子治疗装备企业的并跑，中广核核技术发展股份有 限公司借鉴我国核电国产化自主化的成功实践，选择走一条"引进、消化、吸收、再创新"的路。 2020年8月，中广核技引进并完整取得国际领 ...
