Information about the Interdepartmental Facilities

The interdepartmental facilities of Radiation research Center consist of radiation facilities, clean rooms, and a laboratory animal facility. The facilities stand on several fundamental principles: interdisciplinarity, fluidity, internationality, and openness to the public. The facilities aim for interchange of researchers from different areas through promotion of collaboration. The facilities open widely the gate for researchers in the University. For more information about the facilities, please contact staff listed bellow.

Irradiation facilities

Main facilities using radiation are cobalt 60 gamma-ray facilities, a 18 MeV electron linear accelerator and facilities for handling radioisotopes. These are open for the researchers in and out of the university.
Gamma-rays are mainly used for the improvement of materials, testing devices working under radiation, sterilization of various samples etc. Typical examples of the new recent researches are radiation-induced surface reactions of solids and radiation effects on the devices of artificial satellites.
Electron beams are applied to investigating the irradiation effects of materials, pulse radiolysis measurements, generating and applying ultra-low intensity beams, and developing new radiographic methods.

About the clean room

The clean room on the 2nd floor of the Radiation research Center consists of three different classes of cleanness; a class 1000 room, a class 100 room, and a class 10 room. A down flow system is used to maintain the cleanliness of these clean rooms. The clean room has three-layer structure. The upper room is the air condition room, and fresh air is introduced from the upper room to the working room through the filter of the ceiling. Then, the air flows down to the bottom room through the grating of the floor of the working room. Therefore, the working room is always kept clean. Users of the clean rooms must wear a dust-free clothing, and then pass through an air shower. Also, ultra-pure water and various kinds of high purity gases can be used in the clean room. Research and development of new materials and new kinds of devices have been extensively carried out by the researchers and students in the university as well as by the researchers of corroborative companies.

About the animal research facility

Our animal research facility primarily accepts small animals such as mice and rats. The facility consists of seven breeding rooms, three experimental rooms, a tissue culture room, and an X-ray machine room. The X-ray machine is used for studying the biological effects of ionizing radiation on laboratory animals.

In researches using laboratory animals, we work in an ethos based on the humane treatment of animals. We are compliant with all pertinent laws and regulations as well as the “Guide for the Care and Use of Laboratory Animals” (provisional), and strive to conduct reasonable animal studies from scientific, ethical, and animal welfare points of view. The use of the animal research facility requires the approval of the Animal Research Committee, and the facility is available for the use only within the University.
