Establishing Health System Resilience to Tackle the Health Security Crisis

Bio

Dr. Masaharu Tsubokura is a professor in the Department of Radiation Health Management at the Fukushima Medical University School of Medicine. After the Fukushima nuclear power plant accident in 2011, he worked with local municipalities in Fukushima and played an important role in the establishment of an internal radiation exposure screening program for local residents. He is also a member of the committee on radiation protection and public health in the cities of Minamisoma and Soma and has actively sought to provide radiation seminars to the public in response to public anxieties about the health effects of radiation exposure.
