Strontium (87Sr/86Sr) mapping: A critical review of methods and
Strontium has four naturally occurring isotopes: 88 Sr, 87 Sr, 86 Sr, and 84 Sr. 87 Sr is formed as the radiogenic daughter isotope of 87 Rb (rubidium); the decay of 87 Rb leads to different abundances of 87 Sr in rocks depending on their age and their original 87 Rb content (Dickin, 1995).

The strontium fraction is purified using ion-specific resin and eluted with nitric acid followed by water. This solution is loaded onto a titanium filament for placement in the instrument. Isotopic compositions are obtained on the strontium fraction using a thermal ionization mass spectrometer (TIMS) or MC-ICP-MS.Strontium-90 (90Sr, half-life of 28.8 years) is one of the major fission products released in the Fukushima Daiichi Nuclear Power Plant accident in Japan. Due to the high concentrations of Sr stable isotopes in marine products, an upper limit for 90Sr isotopic abundance in them is of the order of 1 ppb or less.

Strontium Isotope Analysis « Center for Applied Isotope Studies
Strontium isotopic ratios are widely used as tracers in geological processes and as indicators of provenance in an archaeological context. A significant fraction of the Earth’s 87 Sr is not primordial, but is produced by the decay of 87 Rb. Geochemically, Strontium follows Calcium, while Rubidium follows Potassium; thus, the geological variability of Sr Strontium isotopic and concentration results from archeological skeletons have proved useful in demonstrating human and animal mobility patterns, and dietary life-history. This initiated the movement from proxies to answer these questions.
