We will focus on the assessment of exposure to 50160 Hz magnetic fields in epidemiological studies, in order to highlight the importance and the difficulties of this assessment. The different methods of exposure assessment, their advantages and disadvantages have been extracted from a review of the literature. We based our review on the studies of childhood leukaemia. These exposure assessment methods result in a single value when using wiring code, distance or calculation, in several values when using measurement in space or time. It is therefore necessary to choose a single indicator representing the exposure of the person but there is no demonstrated relationship between any magnetic field indicator and illness. It is also necessary to define a threshold to classify subjects as exposed or non-exposed: 0.3 or 0.4 μT, 50 m or 100 m, etc. In conclusion, to assess the exposure, the underlying epidemiological hypothesis must be first defined. Then the exposure assessment method must be chosen (calculation, measurement, distance?), with the exposure indicator (mean, median, 90th percentile?). All this should be precisely described in the methodology and validated before data collection and the statistical part of the study.
