These three invited speakers were selected as they are closely related to the theme of 18th ICDMFR “Radiation and Peace”.
Mr.Takashi Hiraoka is the former City Mayor of Hiroshima. He was born in 1927 and graduated from the School of Letters, Arts and Sciences I，Waseda University in 1952. He started to work as a journalist in the Chugoku Shimbun (Hiroshima’s Local Newspaper) and later became the editor. Then he moved to the RCC Broadcasting Co. Ltd. as its president. In 1991 he became the City Mayor of Hiroshima, a post he held for 8 years.
He registered the atomic-dome as a world heritage site. Further, he supported activities of Hiroshima exposed people including Koreans, and has continued to support the atomic-bomb survivors. In 1995, he called for a response from people around the world to support the illegality of nuclear weapons. This was in spite of Japanese government’s reluctance to support nuclear disarmament in the International Court of Justice, During his term as City Mayor of Hiroshima, he continually appealed for world peace.
He now works as the executive head of some local Organization. He also supports people such as those in the Kazakhstan and Semipalatinsk areas who were exposed by nuclear experiments in the Soviet Union.
His lecture will be an appeal for peace from Hiroshima.
The other two invited speakers are from the Radiation Effect Research Foundation Hiroshima (RERF). This institute was previously called Atomic Bomb Casualty Commission (ABCC). They are Dr. Nori Nakamura and Dr. Kotaro Ozasa who will give reports on long term health effects of the atomic bombs that fell on Hiroshima and Nagasaki.
Dr. Nori Nakamura graduated from the Osaka University Engineering School (1969), then changed the direction of his studies to Drosophila genetics at the Hiroshima University Faculty of Sciences. After obtaining a PhD degree (Doctorat d’Université) at Paris University South (Orsay) in Genetics in 1973, he became a research fellow at the Department of Radiation Biophysics at University of Tokyo Medical School (1974-1984) and studied radiation mutagenesis in cultured mammalian cells. In 1984, he moved to the Radiation Effects Research Foundation, a cooperative Japan-US research organization for studying late effects of exposure to atomic-bomb radiation. He has studied the inter-individual variation in radiation sensitivity, somatic mutations in blood cells, chromosome aberrations in blood lymphocytes of atomic-bomb survivors, and biological dose evaluation by electron spin (paramagnetic) resonance (ESR, EPR) method, using tooth enamel. He is currently a member of ICRP Committee 1.
At the 18th ICDMFR, he will present two reports on the outcomes of the atomic bomb survivors in Hiroshima. The abstracts are:
How radiation exposure increased the risk of leukemia among atomic-bomb survivors?
Nori Nakamura (Radiation Effects Research Foundation)
Human leukemia frequently involves recurrent translocations. Since radiation is a well-known inducer of both leukemia and chromosomal translocations, it has long been suspected that radiation might cause leukemia by inducing specific translocations. However, recent studies clearly indicate that spontaneous translocations specific to acute lymphocytic leukemia (ALL) actually occur much more frequently than do actual cases of leukemia, while most of the translocation carriers do not develop the disease. I proposed an alternative hypothesis that the radiation-related ALL risk to a population is mostly attributable to a small number of predisposed individuals in whom relatively large number of translocation-carrying, pre-ALL cells have accumulated. This pre-leukemic clone hypothesis explains various known characteristics of radiation-related ALL. The hypothesis can also be applied to chronic myelogenous leukemia, and to young-at-exposure cases of acute myelogenous leukemia.
Why chromosome aberration in lymphocytes did not persist following fetal exposure?
Nori Nakamura, Mimako Nakano, Yoshiya Shimada, Yoshiaki Kodama (Radiation Effects Research Foundation, Hiroshima, Japan)
Cytogenetic tests of blood lymphocytes from atomic bomb survivors have long been conducted at RERF for better understanding radiation doses received by individual survivors. Curiously, however, those who were exposed to radiation as fetuses (in utero survivors) did not indicate any dose effect when they were examined at about 40 years old, which was quite counterintuitive as fetuses are believed to be hypersensitive to radiation. The results were confirmed by mouse experiments (fetal irradiation and cytogenetic examinations at 20 weeks of age). In addition, we found that irradiated neonates also showed the refractory characteristics in recording radiation effects when examined at 20 weeks of age while mice irradiated at a young age started to record radiation effects with the increase of age at the
time of exposure. Animals irradiated at 6 weeks old or older gave the same results as adults. P53 gene status (and hence P53-dependent apoptosis) did not affect the results. It is reported that a drastic shift of the niche for hematopoietic stem cells (HSCs) occurs at around 3-4 weeks of age from liver to bone marrow, and this transition is accompanied by a sharp increase of ATM gene by 10 to 100 times; that is, the level is very low in HSC in fetal liver and at 3 weeks of age (Bowei et al. 2007). Thus, the DNA repair system is not probably operating in HSC of immature animals and hence chromosome aberrations as a result of mis-repair do not take place. Our preliminary data of mammary epithelial cells in rats showed that mammary gland stem cells in fetuses are not less sensitive than those in adults in recording cytogenetic damage. Therefore, it seem that the fate of cytogenetically aberrant cells in fetuses largely differ depending on the tissue. It is not yet understood the relationship between the fate of cytogenetic damage and cancer risk.
Kotaro Ozasa, Hiroshima, Japan.
Dr.Kotaro Ozasa graduated from Kyoto Prefectural University of Medicine in 1981 and was engaged in epidemiology of cancer and other diseases as well as public health activities as a faculty member of the university, then as an associate professor for over twenty years.
He has been Chief of the Epidemiology Department at the Hiroshima Laboratory of the Radiation Effects Research Foundation since 2008.
He received a Fellowship of the Faculty of Public Health of the Royal College of Physicians of the UK in 2009.
“Epidemiological studies of the late heath effects of atomic-bomb radiation in Hiroshima and Nagasaki”
The Atomic Bomb Casualty Commission (ABCC), a cooperative research agency of the US National Academy of Science/National Research Council and the Japanese National Institute of Health of the Ministry of Health and Welfare, started a prospective cohort study in the 1950s called the Life Span Study (LSS) to evaluate the late health effects of atomic-bomb radiation among the survivors of the atomic bombings. In 1975, the ABCC was reorganized as the Radiation Effects Research Foundation (RERF), a private, non-profit foundation funded by the Japanese Ministry of Health, Labor and Welfare and the U.S. Department of Energy, the latter
in part through the National Academy of Sciences. ABCC/RERF research has been in continuous operation since its inception. The initial 120,000 people of LSS have been followed up until death and the cause of death for all subjects and cancer incidence for those living within the catchment areas of the Hiroshima and Nagasaki cancer registries. Around 60% of them died during 1950-2003 and increased the mortality risk of cancer and some non-cancer diseases such as circulatory diseases was observed.
Keynote Speakers will be invited from the early submissions before November 2010. We will contact them before December 2010.

About the concept of
The main stream of the concept of this logo is the flag of Japan. Red and white are used. The right IADMFR logo is imaged as the red center circle of Japanese flag, which means the sun. The sunshine pours a lot of radiations. In the white background, you can see a dove and Torii. Torii is a Japanese word, which means a gate of a shrine. This Torii is the symbol of Miyajima, one of the 2 world heritages in Hiroshima. Miyajima is the name of a holly island, which has Itsukushima Shinto Shrine, the main attraction of Aki no Miyajima, long known as one of Japan's "three beauty spots.
The LOGO means “Radiation and Peace” in Hiroshima!
