VDT

A terminal used in information processing (computer terminal) and entertainment (TV picture tube) that produces an image on a screen (target) by bombarding it with electrons. This causes the fluorescent material that coats the screen to emit light. The effects on workers involved with the use of VDTs have been investigated with respect to a variety of factors. There is no evidence that reproductive or visual health is impaired by working with VDTs. Those who work with VDTs may experience musculoskeletal difficulties if the workplaces are poorly designed. This may be due to the screen being positioned in a way that promotes poor posture, or the chair being of improper design.
