Gamma ionizing irradiation, is generated by the decay of the radioisotope Cobalt 60, with the resultant high energy photons being an effective sterilant for a wide variety of medical device products.
As with all forms of irradiation sterilization, Gamma Beam Irradiation contacting product bio-burden, causes the break up the RNA/DNA of the bioburden, eliminating their ability to function and reproduce.
