Other articles where strontium-90 is discussed: strontium: Occurrence, properties, and uses: …of which the longest-lived is strontium-90 (28.9-year half-life). This isotope, formed by nuclear explosions, is considered the most dangerous constituent of fallout. Because of its chemical resemblance to calcium, it is assimilated in bones and teeth, where it continues ejecting electrons that ...
Strontium-90 of 90 Sr is een instabiele radioactieve isotoop van strontium, een aardalkalimetaal. De isotoop komt van nature niet op Aarde voor. Strontium-90 is een nevenproduct bij kernsplijting en wordt ook gevonden in fall-out. Dit kan gezondheidsproblemen veroorzaken, ...
du strontium-90 incorporé est celle du strontium décrite ci-dessous. La biocinétique de l’yttrium incorporé avec le stron-tium-90 est décrite dans la fiche dédiée à l’yttrium-90(1). Les études cinétiques ont montré la similitude qui caractérise du point de vue qualitatif la distribution du calcium et celle du strontium.
30 de ene. de 2017 · Strontium-90 (90 Sr) is a bone- and teeth-seeking radionuclide 1 that is released in large quantities during nuclear accidents and aerial nuclear testing 2,3,4.Due to its high solubility in water ...
A strontium-90 plume in glacial sediments was studied at the Chalk River Nuclear Laboratory in Ottawa Canada(2). The plume migrated about 300 meters over the course of 30 years. The mobility of strontium-90 was greatest following an accidental spill from a nearby nitrate processing plant that accidentally released high levels of calcium and ...
18 de ago. de 2004 · Sr-90 can be inhaled, but ingestion in food and water is the greatest health concern. 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 so that ...
Стронций-90. Стро́нций-90 ( лат. strontium-90 ) — радиоактивный нуклид химического элемента стронция с атомным номером 38 и массовым числом 90. Образуется преимущественно при делении ядер в ядерных ...
