Industrial radiography

Industrial radiography is a method of inspecting materials for seeing hidden flaws by using the ability of short X-rays, gamma rays and neutrons to penetrate various materials. It is a major element of non-destructive testing.

Industrial radiography for non-destructive testing is used to inspect, among others, concrete and a wide variety of welds, such as those in gas and water pipelines, storage tanks and structural elements. It can identify cracks or flaws that may not be otherwise visible.  These characteristics have made non-destructive testing a key tool for quality control, safety and reliability.

The IAEA promotes the use of non-destructive testing technology to maintain the stringent quality control standards for the safe operation of nuclear and other industrial installations. It helps its Member States train staff in applying the technology and provides necessary equipment. 

The Agency’s long-standing involvement in this programme has led to the establishment of national teams that provide services to industries, training centres and certifying bodies that are responsible for the training and certification of personnel involved in non-destructive testing. In many institutions, these efforts have led to a state of self-sufficiency in this area of technology. 

To guide the IAEA experts involved in the training programmes, and to achieve some level of international uniformity and harmonization of training materials and competence of personnel, the Agency has also published a variety of training guidelines and related publications.
