The decay of Rubidium-82, which undergoes positron emission.. Rubidium-82 is produced by electron capture of its parent nucleus, strontium-82.The generator contains accelerator produced 82 Sr adsorbed on stannic oxide in a lead-shielded column and provides a means for obtaining sterile nonpyrogenic solutions of rubidium chloride (halide salt form capable of injection).
Strontium ranelate, a strontium(II) salt of ranelic acid, is a medication for osteoporosis marketed as Protelos or Protos by Servier. Studies indicate it can also slow the course of osteoarthritis of the knee. [ 1 ]
Strontium-89 (89 Sr) is a radioactive isotope of strontium produced by nuclear fission, with a half-life of 50.57 days. It undergoes β − decay into yttrium-89. Strontium-89 has an application in medicine. [2]
This so-called "black ash" is dissolved in water and filtered. Strontium carbonate is precipitated from the strontium sulfide solution by introduction of carbon dioxide. [55] The sulfate is reduced to the sulfide by the carbothermic reduction: SrSO 4 + 2 C → SrS + 2 CO 2. About 300,000 tons are processed in this way annually. [56]
Strontium chloride is a precursor to other compounds of strontium, such as yellow strontium chromate, strontium carbonate, and strontium sulfate. Exposure of aqueous solutions of strontium chloride to the sodium salt of the desired anion often leads to formation of the solid precipitate: [9] [2] SrCl 2 + Na 2 CrO 4 → SrCrO 4 + 2 NaCl
Strontium hydroxide, Sr(OH) 2, is a caustic alkali composed of one strontium ion and two hydroxide ions. It is synthesized by combining a strontium salt with a strong base . Sr(OH) 2 exists in anhydrous , monohydrate , or octahydrate form.

Plesiotherapy is a radiation therapy modality in which a source of ionizing radiation is placed in contact with the exterior surface of the body. [1]This is as distinguished from teletherapy in which radiation is projected by the source from a distance, from brachytherapy in which one or more sealed sources of radiation are placed inside the body, and from radiopharmaceutical therapy in which ...
