Abstract
A radiation and industrial hygiene survey of video display terminal (VDT) operations was conducted. Ionizing and nonionizing radiation measurements were performed on 136 VDTs of some 530 VDTs in use at three different locations, and air samples of VDT areas were taken to determine worker exposure to airborne chemical contaminants such as hydrocarbons, carbon monoxide (630080), formaldehyde (50000), and acetic acid (64197). X-ray measurements were not distinguishable from background concentrations. Ultraviolet emissions ranged from not detectable 0.00000065 watts per cubic centimeter. Visible radiation levels ranged from 0.29 to 11.7 candela per cubic meter and no measurable levels of radiofrequency radiation were observed. Hydrocarbon concentrations ranged from 1.4 to 4.8 parts per million (ppm) in the VDT areas and carbon-monoxide concentrations ranged from less than 0.1 to 3.0ppm. Acetic acid and formaldehyde were not present in detectable quantities. All chemical contaminant concentrations measured were far below recommended standards. The authors conclude that VDT presents no radiation hazard to employees. Also, employees were not exposed to hazardous concentrations of airborne contaminants.
