Radiography Testing Services In Hyderabad – Radiography uses x-rays or gamma-rays to produce an image of an object on film. The image is usually natural-size. X-rays and gamma-rays are very short wavelength electromagnetic radiation which can pass through solid material, being partly absorbed during transmission.

Thus, if an x-ray source is placed on one side of a specimen and a photographic film on the other side, an image is obtained on the film of the thickness variations in the specimen, whether these are surface or internal.

Radiography is used in a very wide range of applications including medicine, engineering, forensics, security, etc. In ndt, radiography is one of the most important and widely used methods. Radiography testing (rt) offers a number of advantages over other NDT methods, however, one of its major disadvantages is the health risk associated with the radiation.

In general, rt is method of inspecting materials for hidden flaws by using the ability of short wavelength electromagnetic radiation (high energy photons) to penetrate various materials. The intensity of the radiation that penetrates and passes through the material is either captured by a radiation sensitive film (film radiography) or by a planer array of radiation sensitive sensors (real-time radiography). Film radiography is the oldest approach, yet it is still the most widely used in ndt.
