The gamma-ray irradiation facilities consist of three buildings equipped with eight irradiation cells. They covers a wide dose-rate range from 0.2 Gy/h to 10 kGy/h. The Co-60 source in each irradiation cell is stored in a water pool under each cell. The source is elevated upward to the irradiation position in each cell. Each cell is surrounded with 1.3-m-thick heavy concrete walls for radiation shielding.
