There are NO radioactive isotopes in CRT's!
Well there are but only the naturally occurring ones.
The lead is there to provide shielding to/from the magnetic fields
moving the electron beams.
Lead doesn't shield magnetic fields. The lead does shield
(partially) the artificial radiation produced by a 10-25KV electron
beam hitting the screen.
Besides the lead is inside the sweep coils, kind of hard to shield
something that way.
