The Japan Health Physics Society holds the 50th Annual Meeting by collaboration with Japanese Society of Radiation Safety Management. Educational Session is set for young researchers at the meeting. Public dose from natural radiation in Japan is one of the session topics. The radiation dose from natural background is announced to public following the accident at TEPCO Fukushima Dai-ichi NPP accident. Principal radiation sources are terrestrial radiation, cosmic radiation, radon and radioactivity in food. The levels of radiation dose and radioactivity are continuously investigated in Japan. As a conversion coefficient is applied to estimate effective dose from the radiation dose or radioactivity, the revise of conversion coefficient affects the result of public dose. In addition, a life-style is an influential factor on the radiation dose to public, too. Thus, the basic radiation dose and method to estimate radiation dose should be comprehended, if an expert explains the public dose.
