Description

Since the Fukushima Dai-ichi nuclear disaster in 2011, Japanese people’s interest in radiation has dramatically changed．After the incident, most nuclear power plants were switched off and they have not yet resumed operation．This has forced the Japanese government to alter the electric energy policy．Although the energy policy is dependent on public opinion, the general public has little knowledge of radiation and atomic power, because radiation education has not been taught in elementary or secondary schools for approximately 30 years．Hence, the government has created two supplementary texts on radiation—one for elementary school students, and the other for middle and high school students．As radiation experts, however, we felt that many phrases used in the texts were too difficult, and therefore, we launched a survey to gauge dental students’ understanding of the texts, as dental students will routinely use X-rays as part of their work．The survey revealed that the dental students did not fully understand the phrases in the supplementary text for elementary school students．Thus, the method of radiation education needs to be rethought．Furthermore, reports on the radiation knowledge questionnaire helped us realize that radiation knowledge is scarce among high school and university students．There were previously very few teachers who could teach about radiation in junior-high and high schools, and this skill is highly desired．The purpose of the review is to reconsider the history of Japanese radiation education in elementary and secondary schools, to update the current status of public knowledge of radiation, and to explain the status of radioisotopes in the Fukushima Dai-ichi nuclear disaster．
