Abstract

Some characteristics of radiation sources, such as X-rays, electrons, protons, and neutrons used in the nondestructive testing of material, are presented. Detailed information on the quality of inspection possible with X-rays is also presented.

The different types of detectors such as ionization chambers and solid-state detectors are briefly reviewed, while a detailed presentation is made of the characteristics of film. The capability of the radiographic system as described in specifications is presented as the measuring base for competitive methods of image analysis in nondestructive test systems.
