Description

Non-destructive examination technique using non-visible radiation sources such as X-rays (X-radiography), gamma rays (gamma radiography), beta rays (beta radiography), or neutrons (neutron radiography). The high energy particles generated by these types of radiation will penetrate different composition/density materials to varying degrees. The resulting variations of transmission of these radiations are recorded by a detector, generaly radiographic film, thus characterizing the internal compositional structure of an object.

See also radiograph, electron emisson radiography, and electron transmission radiography.
