As stages that Phoenix leaders would play an active role, various fields could be considered. It could be international organizations such as the IAEA and the WHO, education/research institutes of radiation, national and local goverments where nuclear plants are located, medical institutions for radiation exposure and hospitals in cities affected by disaster, as well as private enterprises such as electric power supplier, media, equipment-makers of radiation-related devices. Because the Phoenix Leaders are the human resource with abilities that no one else has, it is expected there would be more fields where they could play an active role.
