Gamma rays do not require significant inputs of electricity to create, as is the case with e-beam or x-rays systems. Gamma rays are high-energy photons produced by the radioactive isotopes cobalt-60 and, less commonly, cesium-137. Gamma rays have penetrability similar to x-rays, which makes these systems comparably suitable for irradiating.
