Caesium is a chemical element with the symbol Cs and atomic number 55. It is a soft, silvery-golden alkali metal with a melting point of 28.5 °C, which makes it one of only five elemental metals that are liquid at or near room temperature.
The most common use for caesium compounds is as a drilling fluid. They are also used to make special optical glass, as a catalyst promoter, in vacuum tubes and in radiation monitoring equipment. One of its most important uses is in the ‘caesium clock’ (atomic clock).
PLEASE NOTE: Turn around time for this analyte is 7-10 business days.
Is Cesium in My Soil or Water Harmful?
Cesium is a radioactive metal that is liquid at or near room temperature. It can contaminate soil, water or air. High exposure to cesium can cause radiation sickness and low-level exposure can increase the risk of cancer. Small quantities of cesium can be found in foods grown in contaminated soils. Areas used for nuclear testing in the past may be contaminated by cesium.
