Detecting Carbon residue within laminated paper with non-distructive measures in the field

Can anyone point out a methode for detecting carbon residue (from partial or electric discharges) within laminated paper without distroying the paper. This methode must preferable be quick and safe without any x-ray-methode (because of the large scaled object under test). or is it possible to detect it with a metaldetector used for tracking metal object in te ground (used by amuteur treasure-finders)?

Thnx for your afford,
Yours sincerely,

Maarten Nijsse

Dear Maarten,

Eddy current should in principle be capable of detecting the carbon residue, since paper is an insulator and carbon is a conductor. The metal detector also works on similar principle but the sensor may be too coarse for this application.
