For TV sets, it's often taken that you need 30 kV to have an X-ray issue. But it depends on the materials on to which the electrons impact. Heavy metals are not good news. Also, be careful about limits. There are many different limits in force, expressed in different units. It's quite a problem. > >2.

There is a device for testing TV sets that may be suitable, but I don't know who makes it. There used to be a list available under the CB scheme, of special test equipment. -- OOO - Own Opinions Only.
