The neutron leakage from medical and industrial electron accelerators has become an important problem and its detection and shielding is being performed in their facilities. This study provides a new simple method of design calculation for neutron shielding of those electron accelerator facilities by dividing into the following five categories; neutron dose distribution in the accelerator room, neutron attenuation through the wall and the door in the accelerator room, neutron and secondary photon dose distributions in the maze, neutron and secondary photon attenuation through the door at the end of the maze, neutron leakage outside the facility-skyshine.
医用和工业用电子加速器的中子泄漏已成为一个重要问题，并且在其设施中正在进行中子泄漏检测和屏蔽。本研究提供了一种新的简单设计计算方法，用于对这些电子加速器设施的中子屏蔽进行分类，分为以下五类：加速器室内的中子剂量分布、加速器室内中子通过墙壁和门的衰减、迷宫中的中子和次级光子剂量分布、迷宫末端门处中子和次级光子的衰减、设施外的中子泄漏——天空反照。
