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 There is no natural Co in existence on earth; thus, synthetic Co is created by bombarding a Co target with a slow neutron source. Californium-252, moderated through water, can be used for this purpose, as can the neutron flux in a nuclear reactor. … See more In 1957, Chien-Shiung Wu et al. discovered the β-decay process violated parity, implying nature has a handedness.
