15 What is a low emission monitor?

Generally, low emission monitors follow the Swedish government's SWEDAC (Swedish Board for Technical Accreditation) MPR II spec's or the stricter TCO (Swedish Confederation of Professional Employees) standards.

Both limit the emissions of VLF (Very Low Frequency) and ELF (Extremely Low Frequency) electric and magnetic fields. Although new monitor technology generates less radiation than older units, additional active and passive shielding mechanisms are installed to further reduce emissions. The majority of monitors produced now fall within the MPR II spec's, though some still do not. The price differential between regular and low- emission units has declined substantially.

The basic specs are as follows: [From www.noradcorp.com/swedish.htm]

Frequency Range                         MPR II          TCO
Electric Fields
Static Field                            +/-500 V        +/-500 V
ELF   5 Hz - 2 KHz (Band I)
