In the issue of New Yorker magazine now on the stands there is a long
article on the general subject of hazards from video display stations.
What I gathered from it was that ionizing radiation such as might be
emitted when speeding electrons hit phosphor is not of much concern,
but that there is very much an open question about biological effects
of the pulsed 60Hz magnetic fields emitted by a typical power supply.
The screen shields that purport to stop ionizing radiation would not
be effective magnetic shields .. the next Maccessory may be a tastefully
welded iron box...
