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 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 allow you to find rebar, stress cables or conduit that you might want to aviod if
you need core through the slab. We currently offer mobile inspection services as well as in house
services. We are licensed to use the following isotopes:
