![]() Internal exposure to Cs-137 through ingestion or inhalation allows the radioactive material to be distributed in the soft tissues, especially muscle tissue, which increases cancer risk. Cesium is the standard for atomic clocks, and actually provides the definition for the second Some of its properties are listed below: 2 Atomic weight. It is a soft, silvery-golden alkali metal with a melting point of 28.5 ☌ (83.3 ☏), which makes it one of only five elemental metals that are liquid at or near room temperature. These blocks are named for the characteristic spectra they produce: sharp (s), principal (p), diffuse (d), and fundamental (f). Caesium (IUPAC spelling cesium in American English) is a chemical element with the symbol Cs and atomic number 55. Elements are organised into blocks by the orbital type in which the outer electrons are found. Cesium is the 55 th element on the periodic table of elements. The atomic number of each element increases by one, reading from left to right. Large amounts of Cs-137 are not found in the environment under normal circumstances.Įxposure to Cs-137 can increase the risk for cancer because of the presence of high-energy gamma radiation. Cesium, with atomic number 55 and atomic weight of 132.905. Exposure to such a large amount could come from the mishandling of a strong industrial source of Cs-137, a nuclear detonation or a major nuclear accident. Other industrial devices that measure the thickness of materials such as paper or sheets of metal.Įxternal exposure to large amounts of Cs-137 can cause burns, acute radiation sickness and even death. cesium (Cs), also spelled caesium, chemical element of Group 1 (also called Group Ia) of the periodic table, the alkali metal group, and the first element to be discovered spectroscopically (1860), by German scientists Robert Bunsen and Gustav Kirchhoff, who named it for the unique blue lines of its spectrum (Latin caesius, sky-blue).Industrial gauges that detect the flow of liquid through pipes. ![]() ![]() Medical radiation therapy devices for treating cancer.Caesium (IUPAC spelling) (or cesium in American English) is a chemical. Wikipedia Rate this definition: 0.0 / 0 votes. Cesium-137 is used in small amounts for calibration of radiation detection equipment, such as Geiger-Mueller counters.
