High-energy electromagnetic waves (radiation) penetrate various materials. The radiation penetrating the material affects the radiation-sensitive films which are placed opposite to the penetrated side of the material in question. These films, which are then subjected to the developing process, show the gaps in the material through which the radiation passes, the thickness and density of the material. This type of imaging method is called radiography. The only limitation in radiography is the material thickness. It can be applied to all kinds of materials except thickness limitation.
Radiation sources for radiographic examination can be X-ray tubes or Gamma ray producing isotopes.
In order to obtain healthy and reliable results from Radiographic Inspection, it is necessary to comply with the standards prepared according to the type and / or type of material, the application standards prepared according to the inspection and acceptance levels.
