Summary : Residential magnetic fields (MF) near power lines were measured for the first time in a representative sample of French dwellings. To create an original sampling frame, the study used tools unusual for epidemiological studies: an ultralight plane that flew over all of the high‐tension and extra‐high‐tension lines in the Cotes‐d’Or district and a video recorder that identified all of the houses around them. The level of MF intensity in these dwellings was higher than that generally found in France (0.05 and 0.01 µT, respectively), but still weak compared with other countries. Linear and logistic regression models were used to determine factors associated with the MF\; both models found that power line proximity and period of construction were the two most significant factors. We also tested a French adaptation of the Wertheimer‐Leeper wire code and found that the mean MF intensity of each level of this adaptation was close to that of the American code. Like it, the French wire code explains only 20 per cent of the MF variations. More precise measurement of personal MF exposure, such as that provided by personal monitoring, is needed to improve the quality of epidemiological studies. |
