Radiography is an important method in Non-Destructive Testing. Materials are inspected for inhomogenities by passing gamma radiation or x-radiation through it to provide an image on a film, thus displaying internal defects.
X-ray testing is possible for materials with a maximum thickness of 50 millimetres and gamma ray testing is possible to materials with a thickness varying from 10 to 120 millimetres. MME Group has a large variety of x-ray tubes for directional as well as for panoramic exposures between 40 and 320 kilovolts. For gamma testing, Selenium-75 and Iridium-192 are the most important sources used. We have radiographic bunkers at all our branches.
