Electromagnetic radiation standards
International standards set to limit electromagnetic emissions from monitors. There are currently
two important standards both derived from regulations originally laid down by Swedish
authorities.
MPR-II
The standard originally proposed by the Swedish National Board of Measurement and Testing. It
set maximum levels of electromagnetic radiation emitted by monitors, and has now been adopted
as a world standard. MPR-II defines maximum permitted electrostatic, magnetic and electric field
levels measured at a distance of 50 cm from the center of the monitor (see table).
TCO
In 1991, the Swedish Tjänstemannens Central Organization (TCO, Swedish confederation of
Professional Employees ) set a standard even more severe than MPR-II, especially for
alternating electric fields (AEF). The TCO standard is more severe since not only are the
permitted field levels reduced compared with MPR-II, but the measuring distance is also reduced
