| 内容記述 | After the nuclear meltdown incident at Tokyo Electric Power Company’s Fukushima Daiichi nuclear power plant in March 2011, citizens are increasingly concernedabout theadverseeffectsofradiationonhealth. Perception and anxiety about risks have been worsened by inaccurate news reports and a lack of information about the incident. In this research, newspaper headlines fromMarch2011toJanuary2012on the Fukushima incident were comprehensively collected and analyzed using text mining. Extracted data were also compared to information transmitted via social media such as Twitter during the same period to examine the following four issues related to features of the two types of transmission, i.e., newspaper headlines and social media, and the relationship between information from the media and anxieties about the adverse effects of radiation on health. 1) Over 10 months after the nuclear meltdown incident, the information most frequently provided by newspapers was that related to radiation mea- surement and surveys but providing few articles directly related to adverse effects of radiation on health. 2) Newspaper headlines combined multiple topics in short transmitted text while, at the same time, the limited information transmitted by social media was exaggerated. 3) Newspapers indirectly explained the adverse effects of radiation on health using concepts such as “danger/risk,” “safety,” “anxiety/dissatisfaction,” and “security.” 4) Many articles used the term “danger/risk” in March 2011 before the degree of radiation exposure had been evaluated reliably. |
