Strontium-90 is a radioactive isotope that is produced as an artificial product primarily in nuclear fission and occurs in the fallout from nuclear explosions and nuclear accidents. In medicine, Sr-90 is used as a radioactive source for superficial radiation therapy for some types of cancer.
5 de feb. de 2024 · Strontium (chemical symbol Sr) is a silvery metal that rapidly turns yellowish in air. Naturally occurring strontium is not radioactive. The most common man-made radioactive form of strontium is strontium-90 (Sr-90). Strontium-90 is produced commercially through nuclear.
17 de abr. de 2024 · Once in the body, Sr-90 acts like calcium and is readily incorporated into bones and teeth, where it can cause cancers of the bone, bone marrow, and soft tissues around the bone. Sr-90 decays to yttrium 90 (Y-90), which in turn decays by beta radiation. Wherever Sr-90 is present Y-90 is also present. Because of the beta radiation, Y-90 poses a ...
Radioisotope Brief: Strontium-90. Half-life: 29.1 years. Mode of decay: Beta radiation. Chemical properties: Chemically reactive; can create halide, oxide, and sulfide compounds. What is it used for? Because Sr-90 generates heat as it decays, it is used as a power source for space vehicles, remote weather stations, and navigational beacons.
Strontium-90 behaves like calcium in the human body and tends to deposit in bone and blood-forming tissue (bone marrow). Thus, strontium-90 is referred to as a "bone seeker," and exposure will increase the risk for several diseases including bone cancer, cancer of the soft tissue near the bone, and leukemia.
