[{"from": "human", "value": "Could you give me a brief overview of this molecule? [60Co]"}, {"from": "gpt", "value": "The molecule is a synthetic radioactive isotope of cobalt with a half-life of 5.2714 years. It is produced artificially by neutron activation of the isotope <sup>59</sup>Co. <sup>60</sup>Co decays by beta decay to the stable isotope nickel-60 (<sup>60</sup>Ni). Cobalt is a metallic element with the atomic number 27. It is found naturally in rocks, soil, water, plants, and animals. In small amounts cobalt is an essential element for life, as it is part of vitamin B12. However, excess exposure is known to exhibit toxic effects. (L29, L30, L2088)"}]
