ABSTRACT:
A detection/identification method for determining the presence of a Mossbauer isotope-containing taggant in a carrier material, e.g., explosives, weapons, currency, tax stamps, or identification documents. The detector includes a Mossbauer isotope-containing detecting substance that is identical to the taggant, and a sensing element responsive to the presence of the tagging substance in the carrier material, provided that the Mossbauer isotope of the tagging substance is in a state of resonance excitation and causes excitation of the Mossbauer isotope of the detecting substance. The sensing element is operatively associated with an indicator for indicating whether or not the sensing element has been actuated. The method is initiated by irradiating the carrier material while in detecting proximity to the detector, with radiation from a radioactive source comprising a Mossbauer isotope-containing substance which corresponds exactly to the taggant.
In the case of explosives, identification of the manufacturer, date of manufacture or type of explosive, may be made even after detonation.
