Artificially produced Radioisotope, Emmiting Gamma Radiations such as Ir-192 and Co-60 are used for Radiography Wels, Casting And Forging assembly to reveal the process of manufacturing. This type of sources are used from a lower thickness of up to 200mm of the specimen.
These types of machines are compact and handy at the site and upstair jobs such as Thermal Power, Gas Power, Fertilizer Etc.
Gamma Radiography is more hazardous to human body so safety precaution are strict to be adopted.
In this method person viewing or interpreting the radiographs should be competent and proper experienced in the manufacturing process to avoid confusion in interpreting with codes, standards to un-necessary repairs.
