Abstract
In this paper, we discuss lay people s perception, recognition and attitudes towards some of the EMF issues from the societal governance point of view. EMF issue has typical feature of newly emerged risk: that is un-reached scientific assessment on its health damage beyond thermal impacts, but uncertainties remain depending on the exposure levels of different frequencies. Under this circumstance, we think "Precautionary framework" will be the main principle for societal governance of this issue, and we carried out the Internet survey on lay people of 5, 000 nationwide in Japan to investigate people' s attitude to precautionary principle. After logit regression analysis, significant factors affecting pro-precautionary measures are: anxiety and dependence of mobile phone use, but anxiety of power line is not significant. This is because individual controllability of factors: usage of mobile phone is controllable for individuals, while power line is not.
