At least, that's the opinion of a very experienced electrical engineer of my acquaintance. According to him, the circuitry of a VDT runs at voltages that are simply \too low/ to produce any x-rays. I'll grant the possibility that some other form of electromagnetic radiation is responsible, but I have never seen any claims that anything below the microwave level (VDTs shouldn't be producing any of that either) is injurious to human health. There have been a number of cases in recent years where VDTs were implicated (accused, anyway) in cases of unusually high levels of miscarriages. The aforementioned electrical engineer, who works for GE, was dispatched to one of their plants to check out even the remote possibility that the VDTs were at fault; he couldn't find anything at all. (Do you suppose it's actually the high-frequency whine that you can hear from some VDTs [and televisions] that's really the culprit? It sounds crazy, but perhaps it's crazy enough to be true.)
