  • It's Elemental - The Element Strontium

    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 system.

  • Strontium - Wikipedia

    Strontium is the chemical element with the symbol Sr and atomic number 38. An alkaline earth metal, strontium is a soft silver-white yellowish metallic element that is highly chemically reactive. The metal forms a dark oxide layer when it is exposed to air. Strontium has physical and chemical properties similar to those of its two vertical neighbors in the periodic table, calcium and barium. It occurs naturally mainly in the minerals celestine and strontianite, and is mostly mined from these.

  • Strontium Element Facts - Periodic table

    Strontium was recognized as a new element in 1790 when Adair Crawford analyzed a mineral sample from a lead mine near Strontian, Scotland. Until then scientists had thought strontium and barium were the same element, and only barium’s existence had been recognized. The mineral took its name from the Scottish town and was called strontianite (strontium carbonate). Strontium metal was first ...
