ABSTRACT:
Art objects are authenticated by using a pair of sealed radioactive sources emitting identical gamma ray spectra unique to that pair. One of the sources is attached to a particular, assigned art object. The surface of the other source is engraved with information relevant to the identity of the particular art object. At a late date, the gamma ray spectra of both sources are obtained and compared, and if they are identical, the art object is authenticated.
