The most important artificially radioactive cobalt isotope is 60 Co, with half-life T ½ = 5.27 years. It is widely used as a gamma emitter in gamma-ray flaw detection. In medicine, 60 Co is used primarily in radiation therapy on tumors, as well as for sterilizing medicines. It also serves to destroy insects in grain and fruits and is used in preserving food products.
