Radiographic examination using energy-rich X and Gamma rays can detect discontinuities and defective areas within the entire cross-volume of parts manufactured from different materials. In RT1 trainings, the conditions and differences depending on the material, selection of films and screens, shooting, determination of image quality by penetration parameters and reaching optimum test results are taught. Radiographic testing (RT) is also known as industrial X-ray method. In this method, electromagnetic radiation of short wavelength is applied to the material to find hidden defects in the material. That is, high energy photons are sent into the material. This non-destructive testing method, which is frequently applied in the industry, uses an X-ray machine or a radioactive source.
A similar method is the neutron radiological test method. Neutrons are used in this method instead of photons. This method is preferred because neutrons can easily pass through lead and steel, but are retained by water, oil or plastic. Using X-rays, the details in the material are clearly revealed. In the radiographic examination method, the amount of radiation emitted behind the material is measured. By evaluating the changes in radiation intensity, information is obtained about the thickness of the material or the composition of the material. The radiographic examination method is a very sensitive examination method and the results of the examination can be recorded permanently. Therefore, it is widely used in industry.
When high-energy electromagnetic waves penetrate the material, the internal image of the material through which the radiation passes through the radiation-sensitive films on the other side of the material appears. This image is caused by gaps or density changes in the material. This method can be applied to all materials, both metal and non-metal.
