How is strontium-89 produced?
Strontium-89 has a half-life of 50.563 days and is produced via neutron capture by an enriched strontium-88 oxide target using the DOE’s High Flux Isotope Reactor, located at Oak Ridge National Laboratory. The product has a radionuclidic purity of >99.8% and is sold as strontium chloride solution in 0.1 N HCI.
How is samarium 153 used in medicine?
A radioactive substance used to treat bone cancer and other cancers that have spread to the bone. Samarium Sm 153 is a radioactive form of the element samarium. It collects in bone, where it releases radiation that may kill cancer cells.
Is strontium-90 used to treat cancer?
Brachytherapy using β emitters such as strontium-90 (90Sr) is an ideal treatment technique for these tumors with the advantage of treating only a few millimeters of tissue while sparing the underlying normal eye.
What is the half-life of strontium-89?
Strontium-89 (Sr-89) is a pure emitter with maximum beta energy of 1.46 MeV, average beta energy of 0.58 MeV, and a physical half-life of 50.5 days.
Is strontium-89 still available?
Radiopharmaceuticals should only be used by physicians who are qualified by training and experience in the safe use and handling of radionuclides.
Is strontium used in chemotherapy?
Abstract. Purpose: Strontium-89 (Sr-89) chloride is an effective palliative treatment of the bone metastases of prostate cancer. Chemotherapy has also been shown to have a palliative benefit in this disease.
How is samarium-153 produced?
Samarium-153 was produced by neutron activation of raw materials of Samarium-152 trioxide. Samarium-153 produces beta particles that work to reduce bone pain due to cancer and gamma rays that act as imaging agents and allow patients to perform imaging through gamma cameras.
How is samarium-153 created?
Samarium-153 is produced by the neutron bombardment of isotopically enriched 152Sm2O3 in a nuclear reactor.
Where does strontium-90 come from?
Where does it come from? Sr-90 is produced commercially through nuclear fission for use in medicine and industry. It also is found in the environment from nuclear testing that occurred in the 1950s and 1960s and in nuclear reactor waste and can contaminate reactor parts and fluids.
Where is strontium-90 found?
nuclear reactors
Strontium-90 is found in spent fuel rods in nuclear reactors and is considered a waste product. It is found almost everywhere in small amounts, due to past nuclear accidents and fallout from nuclear explosions.
Is Metastron still available?
Last updated on Feb 13, 2022. The Metastron brand name has been discontinued in the U.S. If generic versions of this product have been approved by the FDA, there may be generic equivalents available.
What are the side effects of taking strontium?
Strontium ranelate might cause side effects such as stomach pain, diarrhea, and headache in some people. This form of strontium is not available in the U.S. Taking very high doses of strontium by mouth is POSSIBLY UNSAFE. High doses of strontium might damage the bones.

What foods contain strontium?
Strontium is a mineral found in seawater and soil. In your diet, you get it mainly from seafood, but you can also get small amounts of it in whole milk, wheat bran, meat, poultry, and root vegetables. Strontium is similar to calcium.
What is samarium therapy?
Samarium Sm 153 lexidronam injection is used to help relieve bone pain that may occur with certain kinds of cancer. The radioactive samarium is taken up in the bone cancer area and gives off radiation that helps provide relief from pain.
What is samarium used for in everyday life?
Samarium is used to dope calcium chloride crystals for use in optical lasers. It is also used in infrared absorbing glass and as a neutron absorber in nuclear reactors. Samarium oxide finds specialised use in glass and ceramics.
What is samarium used for?
Where is strontium found?
Strontium is found mainly in the minerals celestite and strontianite. China is now the leading producer of strontium. Strontium metal can be prepared by electrolysis of the molten strontium chloride and potassium chloride, or by reducing strontium oxide with aluminium in a vacuum.
Where is strontium found naturally?
Strontium in its elemental form occurs naturally in many compartments of the environment, including rocks, soil, water, and air. Strontium compounds can move through the environment fairly easily, because many of the compounds are water-soluble. Strontium is always present in air as dust, up to a certain level.
