RT is a non-destructive testing method
that uses ionizing radiation to inspect materials and components with the
objective of locating and quantifying defects and degradation in materials that
would lead to failure of engineering structures.
RT uses either X-rays, produced with X-ray
generators or Gamma-rays generated by natural radioactivity of sealed
radionuclide sources to examine the internal components by identifying any flaw
or defect.
Inspection techniques are either portable or stationery. It is used in welding, casting parts, composite pieces inspection and coating thickness measurement.
