Strontium Isotopes In Seawater Through Time

Annual Review of Earth and Planetary Sciences, 1989
where pis the p-particle, v is an antineutrino, and Q represents the decay energy (0.275 MeV). The recommended decay constant for 87Rb is 1.42 x 10-11 yr-I (Steiger & Jager 1977), and its half-life T is therefore 48.8 Gyr. On geological time scales, the isotopes 84, 86, and 88 are stable, in contrast to 87Sr, and their abundance ratios are therefore ...

High-Resolution Stratigraphy with Strontium Isotopes

Science, 1985
The isotopic ratio of strontium-87 to strontium-86 shows no detectable variation in present-day ocean water but changes slowly over millions of years. The strontium contained in carbonate shells of marine organisms records the ratio of strontium-87 to strontium-86 of the oceans at the time that the shells form. Sedimentary rocks composed of accumulated

Strontium in the environment: Review about reactions of plants towards stable and radioactive strontium isotopes.

Science of the Total Environment, 2019
Radiostrontium is released to the environment from routine and accidental discharge and acts on living organisms either from external sources or after absorption.
