“Demands for specialists of quantum and radiation engineering in medicine, industry, agriculture, and many more areas has been increased”

Quantum and radiation engineering is applied not only to the foundation of nuclear power generation engineering but also to interdisciplinary fields where advanced science and technology are integrated.
In the 21st century, quantum radiations are applied to diverse areas, such as manufacturing, medicine, food and environment. The economic scale of these areas supported by quantum radiations accounts for a much larger portion than that by nuclear power. It would not be possible to talk about the development of a sustainable society without quantum radiations.

The Department of Quantum and Radiation Engineering aims to develop specialists who can conduct important fundamental research for science and technology, having a wide range of knowledge of quantum radiations relating to advanced science, and contributing to society with a high ethical sense.



“Many opportunities for hands-on training at research facilities, which would not be possible at other universities;
Courses designed to develop highly competent specialists who will be able to play a leading role in the quantum field in the future”

Quantum and radiation engineering is advanced interdisciplinary science, covering quite extensive areas where cutting-edge science and technology in various engineering fields are integrated, based on advanced technology in physics, chemistry, machinery, electricity, substances, materials, and information. It is widely applied in the medical field, such as x-ray examinations, cancer treatment, and sterilization; the industrial field, such as nondestructive tests, ultra-microfabrication, semiconductor technology, and high-molecular polymerization; and the agricultural field, such as breeding of crops and useful microorganisms for fermentation. Its economic scale has become huge, now reaching several trillions of yen. Charged particle beams generated in an accelerator, synchrotron radiation and neutron as secondary beams, and quantum beams, such as various kinds of discharge plasmas, are frequently used as indispensable tools in cutting-edge science and technology fields today.

Quantum and radiation engineering is also essential in the energy field to develop materials necessary to ensure the safer operation of nuclear reactors, to develop materials for nuclear fusion reactors, the ultimate energy source in the future, and to conduct research on fusion plasmas.

The Department of Quantum and Radiation Engineering performs advanced education research utilizing the largest cobalt-60 irradiation field in Japan, significantly much larger than any other facilities owned by universities, accelerators that has been maintained for many years, large-scale radiation-related facilities and safety management technology that no other universities have, and one of the highest level cleanroom facilities among universities in Japan. The objectives of the department are to elucidate the elementary process of the interactions between quantum radiations and substances, to provide practical training and conduct research using related facilities, and to develop specialists in quantum and radiation engineering, which plays an important role in today’s science and technology. The department aims to help students develop profound expertise and outstanding abilities necessary for sophisticated use of radiations and quantum beams, which requires high expertise; the safe operation and maintenance/management of radiation-handling facilities and their supervision and instruction to enable them to become highly qualified engineers and researchers who involve themselves in society and, based on humanity and a high sense of ethics, which are essential to ensure the safe of the society and build its culture, to play a leadership role in radiation-related industries and at safety-regulatory government agencies.
