Kegunaan isotop nikel
- 63Ni (with a half-life of 99 years) is produced from stable 62Ni and is a beta-emitting radionuclide that serves as an electron source together with 55Fe in electron-capture detectors. Electron-capture detectors are used as thickness gauges or as detectors for organic analytes in gas chromatography (Fig. IUPAC.28.2). 63Ni is also used to ionize substances in ion mobility spectrometry–the basis of the instrument used in airports to screen passengers for drugs and bombs. 63Ni is also used as a fluorescence-inducing source in elemental analysis by X-ray fluorescence spectroscopy and in miniaturized long-lived nuclear batteries. Until the mid-1980s, nuclear batteries were used in pacemakers, but then they were replaced by long-lasting lithium batteries.
