  1. Sources of exposure to ELF fields at workplaces.

    In most workplaces people are exposed to a variety of extremely low frequency (ELF) fields.

    So-called'electric jobs'have heen identified, where the exposure is likely to significantly exceed average residential and occupational levels.

    The classification is, however, questionahle, and no reliable exposure data may in general be associated with different jobs.

    Most recent epidemiological studies have been focused on areas where ELF fields are quite intense, sources are clearly identified, and actual field levels can be measured.

    Such areas include electric power generation, transmission and distribution, electric transport, and arc welding.

    In this paper, typical values of magnetic fields in these workplaces are presented and discussed.

    The time-weighted magnetic field values for the same johs are not very consistent across the studies.

    This indicates that not only job titles, hut also measurements of the magnetic field, are poor surrogates for the actual exposure, which is best assessed by the use of dosemeters.
