Shoot, I mistyped-I meant to type "photon". There is radioactive photon waves shooting out of the electron guns. The lead is embedded in the glass to protect you from the photons. Any magnetic field is radioactive. CRTs also have lead in the soldering, the capacitors, and often lead is sprayed on the boards as a fire retardant.
LCDs have there own issues, one being the mercury contained in the backlight. raino On 5/26/05 12:31 PM, "Rick McCutcheon" <[EMAIL PROTECTED]> wrote: > > On 26-May-05, at 1:24 PM, Bruce Johnson wrote: > >> >> On May 26, 2005, at 10:40 AM, [EMAIL PROTECTED] wrote: >> >>> CRTs are nasty items.
