远距离输运填充式屏蔽装置设计

Design of a New Temporary Shielding Device Which Can Be Installed Remotely

为了有效减少人员安装剂量,研发了一种可远距离安装的新型临时屏蔽装置。该屏蔽装置以流态型颗粒状钨粒或铅粒作为主要屏蔽物质,以空气作为输运介质,利用高压气载装置作为主要动力系统,实现了屏蔽物质颗粒的远距离输运填充。该屏蔽装置可为提高现场辐射防护水平提供参考。

In order to efectively reduce the installation dose,a new temporary shielding device that can be installed at a long distance has been developed.The shielding device uses flow-type granular tungsten particles or lead particles as the main shielding material,air as the transport medium,and the high-pressure airborne device as the main power system to realize the long dis-tance transport and filling of the shielding material particles.The shielding device can provide a reference for improving the level of radiation protection in the field.
