I see that my remark to the effect that CRT's don't emit any radiation
except visible light caused quite a reaction, due, I suppose, to the
fact that I didn't take care to mention all the facts, which were
subsequently enumerated by many netters.

A few of you understood my statement in the sense that I intended, which was
to raise a protest against the notion that CRT's posed a health hazard due to
the ionizing radiation that they emit.  The article to which I was responding
was asking whether gas plasma screens are any less of a health hazard in
regards to their emission of radiation.

I knew perfectly well that crt's emit radio frequency and audio frequency
electromagnetic radiation, and I know that the larger CRT's may even emit
an X-ray here or there.  But the point is that they are so infinitesimally
weak that they can be ignored.  

It seems to be one of the characteristics of our modern society that
there is a lot of concern about the infinitesimally small risks, while
ignoring the major ones.  But that is a topic for a different newsgroup.
