Children's Exposure to Extremely Low Frequency Magnetic Fields: A Personal Exposure Measurement Study

This study measured exposure to extremely low frequency magnetic fields (ELF-MF) of 172 children in Switzerland and Italy by means of portable exposimeter devices, twice, in summer and winter season. The data is supplemented by information from a time-activity diary, GPS data, a questionnaire about possibly exposure relevant factors and bedroom measurements, in order to learn more about the levels and temporal patterns of ELF-MF exposure of children in their daily lives. The aim of this paper is to assess reproducibility of personal and bedroom measurements, investigate exposure relevant factors for personal exposure and to compare summary measures of personal and bedroom measurements.
