Residential Power-Frequency Electric and Magnetic Fields: Sources and Exposures
The power-frequency magnetic fields found in homes are surveyed, concentrating on background fields. The aim is to survey the present state of knowledge and to highlight aspects of the fields in homes which are relevant to epidemiological studies. Wherever possible, emphasis is given to comparisons between different countries. Aspects of fields which are considered are: the sources of background fields; the strengths of average background fields in different countries; other features of the fields - harmonics, ellipticity, direction, relation to the static field - and other factors which are associated with the strength of the field in a home; the relative contribution of different sources of field to total personal exposure, assuming various exposure-response relationships; the way in which fields vary over time; and finally, the ways in which electric fields differ from magnetic fields, and the sparse information available on average electric fields.
