Radiographic Testing Equipment category that uses X-rays and gamma rays to inspect internal defects and structures within materials through penetrating examination. Includes industrial X-ray equipment, gamma ray source devices, digital radiography systems, film processing equipment, dosimeters, and lead shielding materials. Essential inspection equipment for quality control and safety assurance in manufacturing industries, including detection of internal defects in welds, void inspection in castings, corrosion evaluation in piping, and internal structure verification of electronic components. Unlike other non-destructive testing methods such as ultrasonic testing or magnetic particle testing, this category focuses specifically on equipment utilizing radiation-based penetrating imaging for internal inspection.
