The radiography testing method is nondestructive testing is used to detect changes in the composition of any material.

Detailed Explanation

Non-destructive testing (NDT) is a testing and analysis technique used by industry to evaluate the properties of a material, component, structure, or system for characteristic differences or welding defects and discontinuities without causing damage to the original part.

Examples of Non-destructive Testing are

• Ultrasonic Testing (UT)
• Radiography Testing (RT)
• Eddy Current (Electromagnetic) Testing (ET
• Magnetic Particle Testing (MT)
• Acoustic Emission Testing (AE)
• Liquid Penetrant Testing (PT)
• Leak Testing (LT)

Radiography enables us to detect the change in composition. X-rays or γ-rays are used in radiography techniques. This method of testing makes use of X-rays, produced by an X-ray tube, or gamma rays, produced by a radioactive isotope.
