In the event of a terrorist attack using a radioactive source, we should care not only about health concerns of victims, especially including first responders who suffer from radiation injury, but also public health activities with affected people during the long recovery phase. Regarding the radiological public health viewpoint, preventive efforts are also important. In fact, regulatory reform is progressing in Japan according to the code of conduct issued by IAEA. One of the difficulties of countermeasures for the security of radioactive sources in Japan is to establish a disposal facility for disused sealed radioactive sources, since radioactive waste has been additionally a point of contention in society since the nuclear disaster. This paper presents an overview of countermeasures for terrorist attacks using a radioactive source, from the viewpoint of public health in Japan including the results of survey targeted hospitals equipped with blood irradiation machines. keywords: radiological terrorist attack, security of radioactive sources, blood irradiator machine, radiological public health (accepted for publication, 6th October 2016) , Minami, Wako-shi, Saitama, -, Japan.
