A metallic element.
A yellow metallic element, absorption of which causes bone damage when its atoms displace calcium in bone. The radioactive isotope strontium-90, which emits beta rays, is used in radiotherapy for the ‘contact therapy of skin and eye tumors.
A dark yellow metal; atomic weight, 87.62; atomic number, 38; specific gravity, 2.6. Medically it is of interest because its radioactive isotope 90Sr constitutes a radioactive hazard in fallout from atom bombs. The isotope has a half-life of 28 years and is stored in bone when ingested.
A metallic element is found in diverse compounds within specific minerals, seawater, and marine plants.
A radioactive form, known as strontium-90, is generated through nuclear reactions and can exist in nuclear fallout. This type of strontium collects in bones, emitting radiation that could lead to the development of leukemia and/or bone tumors. Different radioactive variations of strontium have been utilized in diagnosing and treating specific categories of bone tumors.
