Glossary

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 (see table).

Electromagnetic radiation standards

EMI (Electrical Magnetic Interference)

The electrical and/or magnetic radiation coming from the working electrical or electronic equipment.

EMS (Electrical Magnetic Sustainment)

The ability of electrical or electronic equipment to function properly in the environment with electrical and/or

magnetic interference.

Flicker

Very rapid variations in picture intensity caused by the finite time required for the electron beam to scan a

picture onto the screen. Two kinds of flicker occur: line flicker caused by the electron beam scanning-in each

line of the picture; and frame flicker (or field flicker if the picture is interlaced) caused by the frame repetition

rate of 50 frames/second. Frame flicker is noticeable with GUI and DTP software (which have a light

background), and can be very disturbing, especially for those who work regularly with displays - contributing

to eye strain, headaches, visual blurring, stress, etc. The problem can, however, be eliminated by increasing

the refresh rate (number of frames/second) of the monitor to a value above around 70 Hz. Sensitivity to

flicker appears to diminish with increasing age.

Hertz

The unit of frequency named after the physicist Heinrich Hertz (1857-1894). 1 hertz (Hz) is equal to 1

cycle/second.
