WebCobalt-60 (60Co) and caesium-137 (137 Cs) are the most widely used sources of gamma radiation. 60 Co produces gamma rays with energies of 1.173 and 1.332 MeV and has a half-life of 5.27 years, whereas 137 Cs produces gamma rays with an energy of 0.662 MeV and has a longer half-life of 30.1 years. For both isotopes, the gamma rays energies are ... WebContents: the radioisotope Cesium-137; Activity: 0.37 GBq (=10 mCi) Transport Index: 0.8 means at 1 meter from the surface of the labeled package, the radiation dose rate should be no more than 0.8 mrem/hr (0.008 mSv/hr). If a higher level is measured, the package may have been breeched.
