Is the stream of electrons that make it through the glass on a CRT tube

Is it technically Beta radiation?
Since the source is not a radioactive element, it's not strictly
speaking beta radiation. However, the particles are identical
(electrons).
Beta electrons are given kinetic energy by the difference in binding
energy between parent and daughter nuclei. CRT electrons are given
kinetic energy by a transformer voltage.

If there is sufficient lead embedded in the glass in a CRT, why isn't
the front opaque or at least tinted by the lead?
Thanks.
You don't see the electrons. You see light from phosphorescent paint
that glows when electrons hit the surface.
