  • Strontium Isotope Analysis « Center for Applied Isotope

    Strontium Isotope Analysis 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.

  • Strontium History, Uses, Facts, Physical & Chemical

    OccurrencePhysical CharacteristicsChemical CharacteristicsSignificance and UsesHealth HazardsIsotopes of StrontiumThere are sixteen naturally occurring isotopes of strontium. Naturally occurring strontium has four stable isotopes: strontium-84, strontium-86, strontium-87 and strontium -88. The most abundant stable isotope is strontium-88 (82.58 %). Strontium-87 is thought to be produced during the Big Bang and is also obtained during the radioactive decay of rubidium. The radioactive isotope, strontium-90 is produced as a byproduct of nuclear fission reaction.
