Radiographic Testing (RT)

Last updated May 17, 2025, generated by Sumble

What is Radiographic Testing (RT)?

Radiographic Testing (RT) is a non-destructive testing (NDT) method that uses ionizing radiation, such as X-rays or gamma rays, to inspect materials and components for internal flaws and defects. The radiation passes through the object, and the variations in radiation intensity are captured on film or a digital detector. These variations reveal differences in material thickness and density, indicating the presence of cracks, voids, inclusions, or other anomalies. RT is commonly used in industries like aerospace, oil and gas, and manufacturing to ensure the integrity of welds, castings, and other critical components.

What other technologies are related to Radiographic Testing (RT)?

Radiographic Testing (RT) Competitor Technologies

Ultrasonic Testing (UT)

UT is a volumetric NDT method like RT, often used as an alternative to radiography due to its ability to detect subsurface flaws without the use of ionizing radiation. UT can often be performed faster, and is safer for operators.

Radiographic Testing (RT) Complementary Technologies

Liquid Penetrant Testing (PT)

PT is a surface NDT method used to detect surface-breaking flaws. It can be used in conjunction with RT to provide a more complete inspection, where RT detects internal flaws and PT detects surface flaws.

Magnetic Particle Testing (MT)

MT is a surface NDT method used to detect surface and near-surface flaws in ferromagnetic materials. Like PT, it complements RT by detecting surface flaws that RT may not easily detect.
