Radiographic Inspection

To detect sub-surface flaws in materials, x-rays from high voltage x-ray machines or gamma rays from radioactive isotopes e.g. iridium 192, is placed close to the material to be inspected, passed through the material, captured on film, processed and image obtained for analysis. While the choice of x-ray or gamma ray depends on the thickness of material for inspection, Allied Inspection Services is ever conscious of hazardous effects of both gamma rays and x-rays and therefore use them under controlled conditions and with special precautions.
