Hello, I would not recommend anyone mess with x-ray producing items without
"real" ionizing radiation detection equipment. The CD "civil defense" items
you speak of, will be no good to the Tesla coil enthusiast who may be
producing 100 to 1000 mR/hr dose rates, as those Victoreen meters are made
to measure R/hr dose rates, of up to 0-500 R/hr on the high scale. I would
not want to be the  poor sap too have to use such a meter. They were for
Nuclear war type dose rates :-(

Stay clean,

David Trimmell
