Nagasaki University

In the framework of the 21st Century COE Program “International Consortium for Medical Care of Hibakusha and Radiation Life Science”, a world-class academic research consortium, we intend to establish a pivotal center for education/research, with close focus on local populations in Chernobyl and Semipalatinsk, as well as on Atomic bomb survivors. Moreover, in the context of social issues, including the NPP construction rush in Asia, radioactive waste disposal and expanding medical exposure, the COE will emphasize education/research in the three disciplines: (1) international radiation health sciences; (2) A-bomb disease medicine, and (3) radiation basic life sciences. Interdisciplinary approaches will be employed to enhance the quality of individual educational/research projects and to integrate basic and clinical research. Specifically, we will link bench work at laboratories with world-scale fieldworks unique to Nagasaki University; that is, medical cooperation and academic joint research on the radio-contaminated area and the radiation-exposed populations, with the aim of benefiting the public from the research outcomes.

To this end, it is critical to establish a discipline of “Radiation Health Risk Control” based on research in the world’s radiation-exposed populations, and to develop “human resources” who will become leading figures in the field of radiation medical sciences worldwide in cooperation with the research institutes in the US and Europe, WHO and other international organizations. The COE finally seeks to make Japan-driven, creative, social and international contributions.


Through interdisciplinary attempts to link A-bomb disease medicine and international medical care for Hibakusha with radiation basic life sciences, we seek to establish a scientific organization for risk assessment at both the population and individual levels. Furthermore, comprehensive educational/research organization for radiation health effects regarding internal and external exposures will be established, and the discipline will be also established in “Radiation Health Risk Control,” which will emphasize risk communications with Hibakusha, thereby developing comprehensive “Medical Care for Hibakusha.”


The overall target of the three fields, international radiation health science research, A-bomb disease medical research and radiation basic life science research combined, is to promote molecular epidemiological survey/study and basic research on radiation carcinogenesis, in collaboration with overseas centers for field works and COE research centers in the US and Europe, thereby establishing a “novel discipline providing scientific evidence for radiation health risk assessment/management” at the individual level, as well as at the population levels. These achievements will be integrated so as to emerge in 5 years as new interdisciplinary development in the form of “Medical Care for Hibakusha” and “Radiation Health Risk Control”. Therefore concrete targets for achievement in research activities are as follows.

- Scientific Research aspect
Identification of signature gene(s) or sensitive gene groups relating to radiation carcinogenesis.
(2) Molecular biochemical, molecular pathological and molecular biological characterization of radio-responsive gene groups involved in chromosomal/genetic instability.
(3) Elucidation of differences in molecular mechanism of carcinogenesis between early and late carcinogenesis in the same organs in the young exposed.

- Medical aspect
Planning and implementation of international joint research projects for medical care for Hibakusha, and establishment of the guidelines for radiation safety for low-dose exposure.
(2) Establishment of comprehensive holistic medical care for A-bomb survivors.
(3) Development of radiation health risk assessment at the individual levels as well as at the population levels.

- Socio-medical aspect
Formulation of the world-standard radiation health risk management program and safety guidelines for radiation exposure, as part of joint programs with WHO, IAEA and COE research centers in the US and Europe.
(2) Provision of guidelines in the field of medical radiation exposure and radiation emergency.
(3) Implementation of education/training program in the field of radiation medicine, which thus far has targeted the former USSR, in Asian countries (particularly those with increasing nuclear power plants) so as to establish an Asian network for comprehensive cooperation in medical care for Hibakusha, as well as an Asian network for radiation emergency.
