||Video display terminals (VDTs) are commonly used for information display together with a computer and keyboard. Questions have been raised about adverse health effects associated with the electric and magnetic fields found near the cathode ray tube (CRT) used in a VDT. Television receivers also use CRTs in a similar fashion but concerns about health effects have centered on the VDT, perhaps because it is usually used in closer proximity. Neither laboratory nor epidemiological research has shown convincing evidence that the electromagnetic fields emanating from VDTs adversely affected the health of VDT operators. Studies of effects on pregnant women using VDTs have failed to establish a link between VDT fields and miscarriages or birth defects. However, not all research issues have been settled and it will be valuable for research to continue until it is possible to come to a still firmer conclusion. This paper addresses health issues related to the electric and magnetic fields of VDTs. It was developed by the Committee on Man and Radiation (COMAR ) of the Institute of Electrical and Electronics Engineers, Inc. (IEEE ), and represents the considered judgment of an international group with expertise in the subject area. It updates an earlier statement on this topic that was issued in August 1990.
