||Recent reports indicate that video display terminals (VDTs) can collect radon daughters from the air. This occurs especially when they are turned off and may have negative electric fields which attract positively charged radioactive dust. Various techniques were evaluated for removing the gettered radioactivity while the video display terminal is both off and on. An evaluation was also made of what happens when the video display terminal is switched, thereby reversing the electric field near the screen. In addition, possible inhalation effects experienced by a video display terminal operator during field reversal were studied; it was found that although some radioactivity may be released during the cycle, room air currents redistribute it into the room with no detectable levels being inhaled by users.
