There are two common forms of Radiography, Gamma and X-Ray. Both need certification and proper material handling safety training.

X-Ray Radiography uses a similar image processing techniques that doctors use for x-rays. Radiographic film and the ray source are placed on opposite sides of the material. The film detects exposure to various quantities of radiation received on the film.

Gamma Radiography uses Iridium 192 or cobalt 60 depending on the item being measured. Iridium for ranges of 10 to 50 mm thickness, while cobalt works for steel between 25 to 200 mm thickness.

A critical part of radiography, is tool monitoring and tracking, as they have a components with different half-life limitations.

Focus NDT has developed a well organized tracking and documentation system to ensure that all detection devices meet fitness for purpose standards when used.
