Radiography Testing (RT)
Radiographic testing is one of the most fundamental volumetric testing methods performed in the Non-destructive testing industry.
Radiography encompasses a wide range of techniques from film usage to digital, with digital techniques ranging from computed (CR) and direct (DR) to real-time radiography (RTR).
All of these techniques involve either X-ray or gamma radiation generated from a tube or from an isotope of Iridium-192, Selenium-75 or Cobalt-60.
RT has the ability to penetrate a wide range of material with varying densities to detect internal defects in weld quality; evaluate castings for fabrication flaws or foreign objects; and detect damage in composites.
Relay NDT provides radiographic testing using an x-ray source for the detection of discontinues in ferrous and non-ferrous metals.
Our dedicated team of qualified Level II and Level III technicians for testing, developing and film interpretation ensure that we can customise a solution to any of our Clients needs.
All radiography testing is carried out in accordance with Ionising Radiation Regulations which ensures all legal requirements and legislative notifications are met. To further ensure safety all RT work is controlled by our authorised Radiation Protection Officer (RPO).
Key points:
- Versatile method that can be performed in almost all environments
- Requires minimal surface preparation
- Provides a permanent record of the testing – physical film
