You might borrow a radiation badge from a local hospital X-ray dept.  If you
befriend the X-ray tech I'm sure they will give you a badge to do the test.
Then the tech processes it to check.  This would be a good test --- please
report your results to the Tesla List so we all know.

Best regards,

Dr. Resonance
