In general, the press is considered to have amplified the level of public's anxiety and perception of risk. In the present study, we analyzed newspaper article headlines and Internet contents that were released from March 11, 2011 to January 31, 2012 using text mining techniques. The aim is to reveal the particular characteristics of the information propagated regarding the Fukushima NPP Accident. The article headlines of the newspapers which had a largest circulation were chosen for analysis, and contents of Internet media were chosen based on the number of times they were linked or retweeted. According to our text mining analysis, newspapers frequently reported the “measurement, investigation and examination” of radiation/radioactive materials caused by the Fukushima Accident, and this information might be spread selectively via the social media. On the other hand, the words related to health effects of radiation exposure (i. e., cancer, hereditary effects) were rare in newspaper headlines. Instead, words like “anxiety” and “safe” were often used to convey the degree of health effects. Particularly in March of 2011, the concept of “danger” was used frequently in newspaper headlines. These indirect characterizations of the situation may have contributed more or less to the misunderstanding of the health effects and to the enhanced perception of risk felt by the public. In conclusion, there were found no evidence to suggest that newspapers or Internet media users released sensational information that increased the health anxiety of readers throughout the period of analysis.

Risk assessment of technologies and social activities involves subjective judgment as one of its components, which depends on the perception of risk by individuals. In the present study, we undertook a survey of public perceptions regarding the social issues and risks, the images of radiation, and acceptance of its application and health risk.The majority identified global warming as highly risky among social issues related to technology, and smoking among health-damaging issues, but not radiation-related items such as natural radiation, artificial radiation, and X-ray/CT examinations. In general, a sexual distinction was observed regarding perceptions of sick house and food safety. Forty percent of the public inaccurately believed that the main source of daily exposure was nuclear facilities. Many citizens associated the word of radiation with medical exposure, death/damage/disease and nuclear weapon including A.bomb, and connected the health effects of radiation with cancer and leukemia. However, majority did not bring up any image from the terms of “radiation” and “health effects of radiation”
