Neuton radiography is a method of industrial nondestructive imaging using neutrons to reveal the inner structure of objects. Imaging performed using neutron radiography is called neutron imaging and is particularly useful in applications like non-destructive testing.
Non-destructive testing (NDT) is comprised of a wide array of techniques utilized to evaluate the properties and structures of materials without causing damage to the specimen. Common techniques of NDT are: ultrasound, liquid penetrant testing, radiography, Eddy current testing and coherence interferometry. Each technique is unique and adapted to a specialized purpose.
