Electric and Magnetic Fields
are induced outdoors among others by powerlines or antennas.
Indoors, the many electrical
or electronical devices used at home may generate these fields.
Some Standards recommend
threshold levels above which a long exposure should be avoided for health reasons:
- such as 10 V/m for the Electric
- such as 2 mG for the Magnetic
A cartography of the Electromagnetic
field can be carried out with calibrated devices and expressed under official
reports, e. g. Magelan+ by PSO.
