4.Major reason for recommendation

As a physician and researcher in Internal Medicine specializing in Hematology, Dr. Ichimaru has served as a professor and as Head of the Atomic Disease Institute of the Nagasaki University School of Medicine, and for approximately 40 years has been involved in epidemiological research aimed at clarifying the occurrence of radiation-inducedhematopoietic tumors and cancer of atomic bomb survivors, and in the development and research of treatment methods.

Among those efforts, he is particularly highly acclaimed for his medically outstanding achievements in elucidating the actual facts involved in the high incidence rate of leukemia occurring in Nagasaki since around 1950. Moreover, Dr. Ichimaru has authored numerous journal articles in English that substantiate, both medically and scientifically, the existence and status of atomic bomb survivors suffering the effects of atomic bomb radiation, and has made these available to the international medical community at large. Because of these articles, the fact of the high incidence of leukemia is now well documented in medical literature worldwide.

Additionally, in 1981, Dr. Ichimaru was invited in 1981 to participate in the 1st Worldwide Conference of the International Physicians for the Prevention of Nuclear War (IPPNW), held in Airlie, Virginia in the United States. Ever since that time, as a member of the International Board of Directors, he has been involved in activities aimed at educating and enlightening the Governments of the United States and the Soviet Union at the leadership level with respect to the after-effects of the atomic bomb, efforts which significantly contributed to the IPPNW being awarded the Nobel Peace Prize in 1985.
