Radiography (RT)

Using high resolution imaging to thoroughly evaluate critical materials

Radiography testing uses a radiation source, usually either x-rays or Gamma-rays, to identify material thicknesses and densities in
a given material. In use, the material under test will absorb or scatter the applied radiation at different rates based on these variables, and the variations in exposure are captured on film or electronically for later evaluation and analysis.

Radiography testing offers the benefit of extremely high resolution and low contrast sensitivity. These advantages can be especially important in evaluating extremely small or otherwise hard to detect cracks, flaws or discontinuities in a test sample.

Radiography testing has broad application in a number of diverse industries. In addition to chemical, oil and gas companies, radiography testing is frequently employed to assess materials and components used in military, aerospace, automotive and transportation applications, and by many types of manufacturers for whom material integrity is paramount.

The advantages of radiography testing include:

  • Capable of detecting both surface and subsurface defects
  • Can accurately assess changes in thickness, material density, flaws and corrosion
  • Useful for inspecting and/or verifying internal flaws
  • Requires minimum surface preparation
  • Can be used to assess both materials and assembled components
