Anomalies in 60Ni abundance caused by decay of now extinct 60Fe have been used to study the early history of our Solar System (see section 4.26.2). 59Ni is a cosmogenic radionuclide with a half-life of 7.6×104 years. Decay of 59Ni has been used to assess the terrestrial age of meteorites and to determine abundances of extraterrestrial dust in ice and sediment.
61Ni is used as a radiation target for production of the radioactive isotope 61Cu (with a half-life of 3.3 h), which emits positrons for positron emission tomography (PET) applications using the 61Ni (p, n) 61Cu reaction. 64Ni is used as a radiation target for production of 64Cu (with a half-life of 12.7 h), which is used in radioimmunotherapy by attaching it to an antibody for delivery of cytotoxic radiation (toxic to living cells) to a target cell via the 64Ni (p, n) 64Cu reaction. 60Ni is used for the production of 57Co (with a half-life of 0.75 year), which is used as a reference source for gamma cameras that are used in nuclear medicinevia the 60Ni (p, 4He) 57Co reaction.
