X-ray radiography is the only non-destructive testing technique (besides ultrosonics) that allows for the detection of defects deep within a part. X-rays are generated with an x-ray tube and they pass through the part being inspected and detected by a piece of film. Any defects or abnormalites within a part is captured on the film.
						Typical applications of this technique include:
				Printed Circuit Board Castings Plastic Injection Molding Automotive Parts Aerospace Components Electrical/Mechanical Components Medical Devices
						A Radiograph of a thermal blanket is shown below
