Promoting the application of γ-rays, electron and ion beams to various fields.

γ-Rays irradiation

Various test samples are irradiated with γ-rays to evaluate the radiation resistance for use as components and materials in reactor and space applications, and also to color the crystals and pearls. Cobalt-60 γ-ray irradiation room

Electron beam irradiation

Electron-beam irradiation is used to improve semiconductor material characteristics, examine the radiation resistance of space application parts, and modify polymeric materials. Electron beam irradiation room

Neutron beam irradiation

Silicon irradiation device

Silicon for semiconductors   Neutron irradiation of silicon generates trace amount of phosphorous by a nuclear reaction. The silicon semiconductor production　 method using this reaction is called neutron transmutation doping. This is a special technique which is essential for the production of high quality semiconductors.   RADA is conducting irradiation service using JRR-3 and JRR-4.
