Kegunaan isotop nikel
- 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.
