There are NO radioactive isotopes in CRT's!
We hope, at least!
The lead is there to provide shielding to/from the magnetic fields
moving the electron beams.
Well, actually the X-ray E-field radiation, not H fields, but Our
Buddy Mr. Maxwell explained all that, right? [As I wrap my right

Well, actually E-M radiation. It's caused by electrons above some
voltage hitting a ground potential giving up their energy in the form
of X-Rays. Medical diagnostic X-Rays are somewhere around 100KV.
Theraputic X-Rays run from 4 to 30 MV and require a radio-isotope or
particle accelerator. Been there, done that.
