There are NO radioactive isotopes in CRT's!
The lead is there to provide shielding to/from the magnetic fields
moving the electron beams.
as I've always understood,
but if the lead is there to shield us from the "magnetic fields
moving the electron beams" then I take it they're not very good for
us either...
a good reason to have LCD screens? Are there similar problems there
that I need to know about too? I've always assumed it was one of
the key selling features (besides obvious size / weight issues).
Power consumption also. LCDs only use a fraction of the power of the
same sized CRT.
And, not to lose the main point, approx. 7.5 pounds of lead per
monitor means there is a lot of lead going into landfill sites!
I don't know of anything in an LCD display that is nearly as bad as
the lead. I don't think there is anything. No one really seemed to
care about what was in a CRT monitor until LCDs provided an
alternative.
We may not find out until a next generation display technology arrives.
