Ces ondes qui nous menacent. Perceptions profanes des risques associés à quatre dispositifs émettant des ondes électromagnétiques.

Thanks to data from the French Environmental Barometer EDF-R&D 2004 (national representative sample of French aged over 15), this paper investigated lay risk perceptions related to exposure to electromagnetic fields (from an electric power-line, a TV, a cellular phone or micro-wave oven). Answers to an opened-ended question suggested that many people worry about such exposure: it may interfere with natural electricity circulating in the human body, disturb the nervous system and cause cancer. These answers revealed a conception of human body, health and disease, and participants referred to various kinds of arguments, from expert knowledge to personal intuition. Statistical analyses showed that risk perceptions related to these four devices were strongly correlated with each other and shared common predictors. These results suggest that these risk perceptions are built within the same perceptive frame. One should not consider them as "false beliefs": they are based on consistent conceptions of the body, health and disease, they are fuelled by the contemporary levelling of knowledge, and they reflect the difficulties experienced by many people living in a changing world.
