Sr stable and long lived isotopes are 84Sr: 0.56, 86Sr: 9.86, 87Sr. Beta-emitters are most hazardous when they are inhaled or swallowed. Strontium is an element number 38 from alkali earth metals family. Some beta particles are capable of penetrating the skin and causing damage such as skin burns. Some radionuclides have half-lives of mere seconds, but others have half-lives of hundreds or millions of years.īeta Particles Beta ParticleA form of particulate ionizing radiation made up of small, fast-moving particles. Half-life Half-lifeThe time required for half of the radioactive atoms present to decay or transform. Get the facts about element Strontium (Sr) 38 from the periodic table. Strontium-90 is a long lived highly radioactive fallout product of atomic-bomb explosions. Used in flares and fireworks for crimson color. It also is found in the environment from nuclear testing that occurred in the 1950s and 1960s as well in nuclear reactor waste. Found in minerals celestite and strontianite. Fissioning that occurs without any outside cause is called "spontaneous fission." for use in medicine and industry. Strontium-90 is produced commercially through nuclear fission fissionThe splitting of an atomic nucleus into at least two other nuclei with the release of a relatively large amount of energy. It has got its name after a town in Scotland, Strontian. The most common man-made radioactive form of strontium is strontium-90 (Sr-90). Strontium is an alkaline metal known for its extremely high chemical reactivity. Naturally occurring strontium is not radioactive. Sr dapat merujuk kepada: Stronsium (Sr), suatu unsur kimia dalam tabel periodik. Strontium (chemical symbol Sr) is a silvery metal that rapidly turns yellowish in air.
