I, Anatolii CHUMAK, was born on October 02, 1946 in the village of Chervone, Kobelyatsky district of the Poltava region, Ukraine, in the family of a rural teacher and a collective farm worker. I graduated from the 8-year’s school, the Kremenchug Medical College, the Kyiv Medical Institute (now Bogomolets National Medical University), and the postgraduate study at the Kyiv Research Institute of Phthisiology and Pulmonology, specializing in allergy and immunology. In this institute I defended my Ph.D. and doctoral dissertations. From 1984 to 1987 I worked at the Kyiv Research Institute of General and Public Hygiene as the head of the Department of Long-term Planning and Management of Medical Science. After the Chornobyl NPP accident in August-September 1986 for 14 days I headed the medical service in 30-km zone as the representative of the Ministry of Public Health of Ukraine. Since July 1987 till now I’m working at the institution with present name the National Research Center for Radiation Medicine of the National Academy of Medical Sciences of Ukraine (its history of changing names and subordinations is too long for a short biography). I was initially the Head of the Department of Clinical Immunology, then the Department of Coordination of Scientific Research, and from 2012 - Director of the Institute of Clinical Radiology and at the same time the Head of Laboratory of Molecular Biology, Department of Clinical Immunology. Married, I have 2 children and 4 grandchildren.
