- n. Variant of cesium.
Century Dictionary and Cyclopedia
- n. Chemical symbol, Cs; atomic weight, 132.8. A rare metal discovered by Bunsen and Kirchhoff by spectrum analysis in the saline waters of Dürkheim in Germany, and subsequently in other mineral waters. It has never been isolated, and is only known in combination. It is a strong base belonging, with potassium, sodium, lithium, and rubidium, to the group of alkali metals. Cæsium, in connection with rubidium, is found most abundantly in the lepidolite of Hebron, Maine. The oxalate and nitrate or cæsium are used in medicine.
Wiktionary
- n. A metallic chemical element (symbol Cs) with an atomic number of 55.
GNU Webster's 1913
- n. (Chem.) A rare alkaline metal found in mineral water; -- so called from the two characteristic blue lines in its spectrum. It was the first element discovered by spectrum analysis, and is the most strongly basic and electro-positive substance known. Symbol Cs. Atomic number 55. Atomic weight 132.6.
WordNet 3.0
- n. a soft silver-white ductile metallic element (liquid at normal temperatures); the most electropositive and alkaline metal
Etymologies
- Latin caesius ("sky-blue"), in reference to the radiation spectra + -ium (Wiktionary)
Examples
“Their light is emitted by vaporised alkali metals such as caesium or potassium. reports they have "mass-to-power ratios that far exceed what is possible with today's other laser systems".”
“Radioactive caesium 137, for instance, mimics potassium and thus can be taken up in plants that are later eaten and the radioactivity concentrated by grazing animals.”
“There has always been a natural level of radioactivity in certain soils – those on a granite substrate for instance – but the caesium 137 fallout from Chernobyl is still relatively high in some areas.”
“In September officials in Yokohama said they had detected 40,200 becquerels of radioactive caesium per kilogramme of sediment collected from a roadside ditch.”
“Per Wikipedia: Mercury is a heavy, silvery d-block metal [that] is one of six elements that are liquid at or near room temperature and pressure, the others being caesium, francium, gallium, bromine, and rubidium.”
“Have you a device by which I might measure the duration of 9,192,631,770 periods of the radiation corresponding to the transition between the two hyperfine levels of the ground state of the caesium 133 atom?”
“Despite the revelation that caesium had been detected, Japanese officials still claim the reactor's container was not damaged and that radiation levels have started to fall.”
The Guardian: Japan nuclear fears as systems fail at second reactor
“It was confirmed that radioactive caesium, one of the elements released when overheating causes core damage, had been detected around the plant.”

“From that sample, radioactive caesium 134 and caesium 137 were also detected in slightly larger amounts than the limits set by law.”
The Wall Street Journal: Elevated Radioactivity Found in Japanese Milk, Spinach
“Health restrictions are still in place at some UK farms after radioactive caesium from the plant blew over and contaminated pastureland.”
The Guardian: Chernobyl lessons missed because of research gaps, says radiation expert
