The Nishina Center for Accelerator-Based Science possesses one of the biggest heavy-ion accelerator facilities in the world which consists of two heavy-ion linear accelerators and 5 cyclotrons. Uranium ions are accelerated here only in Japan. Electron accelerators of microtron and synchrotron-storage-ring are also operated. Our function is to keep the radiation level in and around the facility below the allowable limit and to control the exposure on the workers as low as reasonably achievable. We are also involved in the safety management of the Radioisotope Center where many types of experiments are performed with sealed and unsealed radioisotopes.
