Radiography, isotope, X-Ray, & Computed Radiography

Radiography is a method of nondestructive testing that utilizes radiation to penetrate an object and record images. The images can be recorded on a variety of different devices such as film or photosensitive paper. The result is a two dimensional projection of the part onto the film, producing a latent image of varying densities according to the amount of radiation reaching each area. It is known as a radiograph, as distinct from a photograph produced by light. Because film is cumulative (becoming greater by successive additions) in its response, relatively weak radiation can be detected by prolonging the exposure until the film can record an image, which will be visible after development. The radiograph is examined as a negative, without printing as a positive as in photography.

Radiography gives you the ability to see what’s inside the weld or part you need to have tested. Things you might find in a weld include cracks, porosity, incomplete fusion, or slag as well as many other discontinuities. Taking radiographs of concrete floors allows you to find rebar, stress cables, or conduits that you might want to avoid if you need to core through the slab. We currently offer mobile inspection services as well as in-house services. We are licensed to use the following isotopes:

A digital replacement of conventional x ray film radiography. Computed radiography (CR) offers enormous advantages for inspection tasks. The use of consumables is virtually eliminated (processing chemicals and film) and the time to produce an image is drastically shortened. Imaging plates are reusable. Post imaging software provides image enhancement capabilities.
