Radiography involves the use of penetrating X- or gamma radiation to examine parts and products for flaws that could be detrimental to their intended use. An X-ray machine or radioactive isotope is used as a source of radiation. Radiation is directed through a part onto a film or an electronic device (plate). When the film or plate is processed, a negative-like picture is obtained that shows the internal characteristics of a part. Possible imperfections show up as density changes in the film, in much the same way an x-ray can show broken bones.

RNDT provides radiographic services in both our laboratory and in the field at customer locations. Our custom built mobile darkrooms are easily set up in less than 10 minutes. Our 12' x 12' and 20' x 20' solid concrete wall exposure rooms allows for very large parts to be examined. Also, we provide high volume processing of film with a state-of-the-art ecologically friendly automatic processor. Our Level II and Level III radiographers are experienced in many different specialty techniques involving geometrically challenged parts.
