Patent ID: 7402826

Claim:
A system for non-destructively determining the thickness of an anti-tamper coating material on a part, comprising: a test probe unit, said test probe unit including at least a beta radiation source and a radiation detector arranged proximally to said beta radiation source, said beta radiation source operable to emit radiation directed toward the anti-tamper coating material, and said radiation detector operable to detect at least a portion of said radiation reflected from the anti-tamper coating material and generate a count associated with said at least a portion of said radiation reflected from the anti-tamper coating material; a meter unit coupled to said radiation detector, said meter unit operable to generate a first value associated with said count generated by said radiation detector; and a conversion unit coupled to said meter unit, said conversion unit operable to convert said first value to a second value associated with a level of thickness of the anti-tamper coating material.
