This paper provides a broad overview of the regulatory framework on medical radiation safety and current medical radiation protection issues such as diagnostic reference levels, shielding calculations for X-ray facilities, accidental excessive emissions of gaseous 18F, security of radioactive sources, and induced radioactivity in Japan, and discusses the impact from the 2011 Fukushima nuclear disaster regarding risk communication issues. The Fukushima nuclear disaster has had an inevitable impact on issues related to protection from medical radiation. However by taking this situation, communication activations on radiation are being accelerated in certain initiatives utilizing quantitative risk expression on the premise of seeking fairness for risk allocation to the society.
