Cobalt-60 ( Co) is a synthetic radioactive isotope of cobalt with a half-life of 5.2713 years. It is produced artificially in nuclear reactors. Deliberate industrial production depends on neutron activation of bulk samples of the monoisotopic and mononuclidic cobalt isotope Co . Measurable quantities are also produced as a … See more Corresponding to its half-life, the radioactive activity of one gram of Co is 44 TBq (1,200 Ci). The absorbed dose constant is related to the decay energy and time. For Co it is equal to 0.35 mSv/(GBq h) at one … See more The main advantage of Co is that it is a high-intensity gamma-ray emitter with a relatively long half-life, 5.27 years, compared to other gamma ray sources of similar intensity. The β-decay energy is low and easily shielded; however, the gamma-ray … See more In 1957, Chien-Shiung Wu et al. discovered the β-decay process violated parity, implying nature has a handedness.
