Strontium-90, a radioactive isotope of strontium, is a common product of nuclear explosions. It has a half-life of about 28.8 years and decays into yttrium -90 through beta decay . Strontium-90 is especially deadly since it has a relatively long half-life, is strongly radioactive and is absorbed by the body, where it accumulates in the skeletal ...

The 87 Sr/ 86 Sr ratio of sea water has changed significantly with time in response to the input of varying proportions of Sr derived from continental crust and upper mantle sources, as moderated and buffered by carbonate recycling. Because of these fluctuations, the marine Sr isotope record can be used for stratigraphic correlation and absolute dating purposes.
