An Integrated Non-Destructive Testing Laboratory

Radiographic Testing

Radiography is one of the modern Non-Destructive Testing (NDT) methods. It is a kind of ‘Volumetric test’ used to detect manufacturing fetal flaws inside the material volume/thickness.

Radiography works on principle to create density variation (grayscale) on photo sensitive material (X-ray film) by exposing them using short wavelength electromagnetic radiation (Gamma/X-rays).

Such electromagnetic radiation in form of Gamma/X-ray is capable to penetrate and pass through solid material like metals. This process produces an image of the penetrated object or material on the X-ray film.

Radiography is a well-established technique, which gives a permanent record and is widely used to detect internal flaws in weldments and castings.

Wide range of thickness is covered using variety of radiation sources like X-ray, Ir-192, Co-60, Se-75, Linear particle accelerators and Betatron.

Due to its harmful effects of ionizing radiation on living-organism, X-ray/Gamma Source should be handled under strict safety procedure and supervision of qualified personnel.

We at I TECH strictly follow safety procedures while working with radiation sources. Also, I TECH has safe industrial radiography Enclosures and safety equipments approved by BARC (Bhabha Atomic Research Center).
