目標：探討台灣民眾對基地台、高壓電線、變電箱、手機、微波爐與無線網路所感知的利益、健康風險與對管制的信任程度。方法：本研究於2008年10月，委託中央研究院調查訪問中心，以電話抽樣完成2,035例18歲以上民眾的橫斷性調查訪問。結果：台灣民眾對不同來源電磁場的利益、風險與管制信任互有相關，但是手機使用頻率只與對手機和基地台的利益感知有關。一般線性模式的分析發現，影響民眾對高壓電線與基地台高風險感知的變項，除了女性與高教育程度之外，還包括低利益、低信任，以及同意電磁場會導致癌症。結論：本研究建議政府相關單位加強民眾對電磁場的管制信任，並增加補助電磁場健康風險研究，以降低民眾疑慮。

Objectives: To explore the perceived benefits, risks and regulatory trust with regard to electromagnetic fields (EMF) from various sources (including mobile phone base stations, power lines, transformers, mobile phones, microwave ovens, and wireless internet) in Taiwanese people. Methods: A cross-sectional telephone survey was conducted by the Center for Survey Research, Academia Sinica in October, 2008, with a randomized sample of 2,035 adults aged 18 and older. Results: The benefits, risks and regulatory trust perceptions of various sources of EMF were all correlated. The frequency of mobile phone usage, however, was correlated only with the perceived benefit of mobile phones and base stations. General linear model analysis indicated that female, higher education, low benefit, low trust, and agreement that EMF is carcinogenic were the major factors determining the perception of risk from power lines and base stations. Conclusions: We suggest the regulatory agencies in Taiwan increase the general population’s trust for EMF regulation. Further, the government should sponsor further EMF health risk studies in order to reduce public concerns.
