防辐射大体积重晶石混凝土施工技术

Construction Technology of Large-volume Radiation Proof Barite Concrete

医院中直线、回旋加速器等设备在运行过程中会产生穿透能力极强的γ射线和中子流,需要采取有效的屏蔽措施,以免对人体产生危害。重晶石混凝土相比于其它防辐射材料,具有施工难度低、成本低、防辐射质量好等优点,在医院工程中得到了广泛的使用。本文介绍了复旦大学附属中山医院厦门医院工程重晶石混凝土的施工要点,结果表明本施工方法具有较好的可靠性,亦可为其他相关工程借鉴使用。

In the hospital, the operation of linear, cyclotron and other equipment can bring the Gamma rays and neutron flow with strong penetration ability. Effective shielding measures should be taken to avoid harm to human body. Compared to other radiation proof materials, barite concrete has low construction difficulty, low cost, good quality of anti radiation and other advantages. And it has been widely used in the hospital project. This paper introduces the key points of construction engineering of barite concrete in Xiamen Hospital of Zhongshan Hospital Affiliated to Fudan University. The results show that the construction method has good reliability, and can be used for reference for other related projects.
