Questionnaire Survey of Fukushima Daiichi Nuclear Power Plant Workers in 2016 on Knowledge and Anxiety About Radiation

The results of a survey of radiation workers suggest that they are worried about the effects of radiation exposure on health, and approximately 30% of Fukushima Daiichi Nuclear Power Plant (FDNPP) workers have anxiety. This questionnaire survey reveals that the higher the frequency of radiation education, the higher the knowledge of radiation the workers will have, and that the higher the level of knowledge, the lower the anxiety. To reduce anxiety, it is important to increase knowledge about radiation through radiation education. However, even those workers who had radiation education several times still had anxiety. According to the Ordinance on the Prevention of Ionizing Radiation Hazards, the time spent on education about the effects of radiation on the human body is only about 30 minutes. This education is not enough to reduce anxiety. FDNPP workers needed more effective education to increase their knowledge and to reduce their anxiety.
