Radiographic Examination Or Testing
Definition - What does Radiographic Examination Or Testing mean?
Radiographic Examination or Testing is a non-destructive testing method used to inspect materials with the help of its short wavelength electromagnetic radiation. From security to forensics, radiographic testing is used in a broad range of applications. It is done by two different radioactive sources, i.e., X-rays and gamma rays. As the tests are highly radioactive thus they should be carried out under strict rules. This technology is used in many industries such as aerospace industries and power generation industries.
Petropedia explains Radiographic Examination Or Testing
The main role of Radiographic Examination or Testing is to examine the cognitive skills and knowledge of tasks. The process can evaluate the thickness and density of a material by penetrating radiation through absorption and scattering. There are a huge number of advantages using the method such as:
- It detects surface and internal discontinuities
- It is inexpensive and offers great portability for gamma-ray sources
- It verifies hidden flaws on complex structures
- It measures dimension and angles within the sample
The major disadvantage of Radiographic Examination or Testing is that it is dangerous to operators and nearby personnel.
