Radiography Inspection (RT) is a method of NDT that uses a gamma radio isotope to take a radiograph of a material being inspected, this allows us to visually determine integrity and wall loss.       

   Sonar uses an Iridium Isotope to perform Industrial Gamma Radiography (RT) to radiograph pipe welds, and vessels, shadow shots can also be performed on piping to determine wall thickness and corrosion.

 Sonar is a member of the CIRSA group and a willing participant in Radiation Safety.

 

 

Below are some examples of common discontinuities found with RT.
