Cobalt rod sources are manufactured in two ways in Pars Isotope Company. In the first method, the cobalt-59 rod is converted to cobalt-60 in a nuclear reactor. This radioactive material wrapped around the metal core in steps proportional to the distribution of radioactivity and then placed inside a tubular capsule made of austenitic stainless steel (316L, 321, 304, 316) with a special design and welded

In the second method, ceramic technology is used for production. In this method, the ceramic core is used instead of the metal core, which according to the distribution of radioactivity appropriate wire steps are applied to the ceramic core. The ceramic is then placed inside an aluminium sheath and welded. Then, this sheath is placed inside a tubular capsule made of austenitic stainless steel (316L, 321, 304) with a special design and welded again. In general, cobalt rod sources are available in the activity range of 0.1 to 50 mCi

Application: In various industries such as steel, petrochemical and steel melting
