Bob,
CRT's have an inner and outer conductive coating (aquadag) with thick glass
in-between, forming a good glass capacitor.  Since the electron gun is not
powered, and no electrons are being accelerated in a vacuum, no X-rays are
possible.  A capacitor, nothing more or less.  The only hazard is a possible
implosion should the glass fail due to a hv puncture.
