  • Strontium 90 EncyclopediaStrontium 90 Sr PubChem

    STRONTIUM 90 When anyone discusses the harmful effects of atomic fallout that discussion primarily relates to strontium 90 90 Sr an isotope created during both nuclear detonations and nuclear power reactions The parent chemical strontium Sr is a silver yellow alkaline earth metal with Strontium 90 has a radioactive decay half life of 29 years while strontium 89 has a much shorter half life 51 days Strontium 90 decays by emission of a beta particle with a maximum energy of MeV and the creation of a yttrium 90 isotope which is also unstable
