![]() ![]() 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. 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 is the standard for atomic clocks, and actually provides the definition for the second Some of its properties are listed below: 2 Atomic weight. Cesium is the 55 th element on the periodic table of elements. Pronunciation Guide This video shows you how to pronounce Caesium (metal, chemical element. The caesium standard is a primary frequency standard in which the photon absorption by transitions between the two hyperfine ground states of caesium-133 atoms is used to control the output frequency. Cesium, with atomic number 55 and atomic weight of 132.905. 23 2.3K views 2 years ago Pronounce Science Words Chemistry, Physics, Mathematics. 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. A caesium atomic fountain used as part of an atomic clock. Cesium chloride is used in analytical chemistry applications as a reagent, in high-temperature solders, as an intermediate in cesium metal production, in isopycnic centrifugation, as a radioisotope in nuclear medicine, as an insect repellent in agricultural applications, and in specialty glasses. 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. ![]() Industrial gauges that detect the flow of liquid through pipes.The metal itselfwhich is soft, white, and lustrousand several of its alloys and compounds are produced on an industrial scale. Medical radiation therapy devices for treating cancer. lithium (Li), chemical element of Group 1 (Ia) in the periodic table, the alkali metal group, lightest of the solid elements.Symbol: Cs atomic no: 55 atomic wt: 132.90543 valency: 1 relative density: 1. The radioisotope caesium-137, with a half-life of 30.2 years, is used in radiotherapy. It occurs in pollucite and lepidolite and is used in photocells. Cesium-137 is used in small amounts for calibration of radiation detection equipment, such as Geiger-Mueller counters. Caesium definition, a ductile silvery-white element of the alkali metal group that is the most electropositive metal. ![]()
