Radiographic inspection is a nondestructive testing technique used to evaluate objects and components for signs of flaws which could interfere with their function. It is accomplished with the use of radiographs, images generated by bombarding the object under inspection with radiation. X-ray and gamma ray radiographic inspection are the two most common forms of this inspection technique. Materials testing companies often offer radiographic inspection to their clients, and some companies have their own inspection facilities for in-house inspections.
