In the present invention, a system and method are disclosed for distinguishing PEN from other types of materials. The method and system discloses an electromagnetic radiation source which transmits electromagnetic radiation to an object.

This amount of penetrating or reflecting electromagnetic radiation is then measured to classify the item by type.
