National Institute of Radiological Sciences



As a development of the Nuclear Regulation Authority and Agency’s nomination of the National Institutes for Quantum and Radiological Science and Technology (QST) as a Core Center for coordinating and guiding four Advanced Radiation Emergency Medical Support Centers (Hirosaki University, Fukushima Medical University, Hiroshima University and Nagasaki University) in Japan, the QST Center for Advanced Radiation Emergency Medicine (AREM) was newly established in April 2019. However, again reorganization of QST in Chiba area brings the new name from AREM to the National Institute of Radiological Sciences (NIRS) integrating the two departments; Radiation Effects Research and Radiation Regulatory Science Research. The original NIRS was established in 1957 closely linked to the historical involvement in Daigo- Fukuryumaru, in order to solve negative consequences of radiation exposure and simultaneously to promote utilization of radiation in the field of medical diagnosis and treatment but now “the General” in Japanese naming disappears.

The new NIRS, with renewed confidence, is striving to strengthen our educational and training course, to improve the contents of educational and training materials, to develop common guidelines/manuals for biological and physical dose measurement and estimate, and to cultivate human resources in the field of Radiation Emergency Medicine. In addition, we will concentrate on development of technology and research on Radiation Regulatory Science, and promote basic and clinical research on Radiation Effects

It is well known that in the Medical field, patients in front of us are always live textbooks. Similarly, in the case of nuclear disaster or radiological accident, it is difficult to solve the problems and to manage those simply using a conventional guideline and an approved manual. Indeed, organizational response and risk management after a disaster or accident face many difficulties as for how to build up the on-site capability and human power. Therefore, at the individual level we all should make a constant effort and encourage our mind through research and development, further relying on a good supporting system. 

One of the lessons learned from the Fukushima Nuclear Power Plant Accident apparently demonstrates the necessity of narrowing the gaps of knowledge between the experts and the public, and a system for coordination and effective management between multiple professional areas. On a basis of our own wide knowledge and experience accumulated in QST activities, we plan to cooperatively deepen our educational and training programs, and to promote human resource development program in order to be ready to manage unexpected and critical situations.

As a Core Center of the national level, we will work with the four Medical Support Centers, related organizations, research institutes and universities, domestic and abroad, to fulfill our mission and play a major role in enhancing Japan’s preparedness and ability to respond to nuclear disasters and radiological accidents.
