Industrial x-ray: The radioactive source you didn't know about.

A hand holds a clear, circular plastic case containing small metallic components labeled as 'SENTINEL™ Ir-192 Wafers' and 'Double-Encapsulated Radiography Source'. The case also displays 'www.SENTINELNDT.com' and 'Inactive Sample'. The hand is resting on denim fabric, and the text is printed directly on the case. The image is a product shot of a non-functional radiography source sample.
