  • Radiographic Testing

    Radiographic Testing (RT), or industrial radiography, is a nondestructive testing (NDT) method of inspecting materials for hidden flaws by using the ability of short wavelengthelectromagnetic radiation (high energy photons) to penetrate various materials.

    Either an X-ray machine or a radioactive source, like Ir-192, Co-60, or in rarer cases Cs-137 are used in a X-ray computed tomography machine as a source of photons. Neutron radiographic testing (NR) is a variant of radiographic testing which uses neutrons instead of photons to penetrate materials. This can see very different things from X-rays, because neutrons can pass with ease through lead and steel but are stopped by plastics, water and oils. Most industries are moving from film based radiography to a digital sensor based radiography much the same way that traditional photography has made this move.

    Since the amount of radiation emerging from the opposite side of the material can be detected and measured, variations in this amount (or intensity) of radiation are used to determine thickness or composition of material. Penetrating radiations are those restricted to that part of the electromagnetic spectrum of wavelength less than about 10 nanometres.

    • Can inspect assembled components
    • Minimum surface preparation required
    • Detects both surface and subsurface defects
    • Provides a permanent record of the inspection
    • Verify internal flaws on complex structures
    • Isolate and inspect internal components
    • Automatically detect and measure internal flaws
    • Measure dimensions and angles within the sample without sectioning
    • Sensitive to changes in thickness, corrosion, flaws and material density changes
