| Resumen |
Radiation emissions were measured from CRT terminals associated with the following kinds of computer equipment: IBM PC (Colour Display); IBM PC-AT (Colour Display); Apple II; P.C. Bass 161; Ericsson Alfascope. The kinds of radiation tested for were: X-rays, ultraviolet (UV), infrared (IR), extremely low frequency (ELF), and radiofrequency (RF) radiations. The potential difference between video display unit and the operator was also measured, as was the level of ultrasound emission. The results of the measurements confirmed that there was no risk from any type of radiation or from ultrasound. There was some measurable potential difference increase (although this was difficult to quantify), but only when the video display units were turned on and off. |
