This is a systematic study on high energy radiation shielding in accelerator facilities of charged particles more than 100 MeV.The research was done for the following items.Transmission properties of high energy neutrons and secondary photons through various shielding materials by numerical calculations. One dimensional Sn transport code ANISN was used with the combination of cross section lifray DLC-87/HILO. The transmission dose distributions of lead, iron, heavy concrete, marble, paraffin, water were obtained.The experimental data on radiation production by heaby iron beam and the produced radiation shielding was obtained at IPCR(RIKEN) cyclotron. Several considerations were done with combining the calculated results.

本文对100 MeV以上带电粒子加速器装置的高能辐射屏蔽问题进行了系统的研究。研究内容包括：用数值计算方法研究高能中子和次级光子通过各种屏蔽材料的传输特性。采用一维Sn输运程序ANISN，结合截面计算程序DLC-87/HILO。获得了铅、铁、重混凝土、大理石、石蜡、水等材料的透射剂量分布，以及在日本理研（IPCR）回旋加速器上获得的重铁束辐射产生和产生的辐射屏蔽的实验数据。结合计算结果进行了几项考虑。
