I used to think the same thing, before I investigated a little bit. It turns
out that there is a significant body of evidence showing biological effects
of magnetic fields near the vertical sweep rate of VDT's, and with the same
amplitudes experienced by some CRT users. Furthermore, there is another
body of evidence that exposure to ELF magnetic fields leads to some
increased incidence of certain cancers.

It is unfortunate that this issue has been snatched up by activists and
Paul Brodeur. It means that reasonable people are apt to deny their claims 
simply because the activists themselves have no credibility. However, just 
because the claims are asserted by activists does not, per se, 
make them invalid.

Also, note that the evidence applies ONLY to ELF magnetic fields. It does
not apply to electric fields, and does not apply to RF energy (unless
amplitude modulated at ELF rates).
