If you have any suspicion that cesium has contaminated your food, water or soil, ETR Laboratories can provide you with the results of a test for $75. Caesium, being one of the heavier alkaline metals, is also one of the most reactive and is highly explosive when it comes in contact with water (even cold water. As a major fission product of uranium, radiocesium widely exists in radioactive wastewater (Clearfield 2010). Areas used for nuclear testing in the past may be contaminated by cesium. Radiocesium removal from aqueous solutions is vital yet challenging. Small quantities of cesium can be found in foods grown in contaminated soils. High exposure to cesium can cause radiation sickness and low-level exposure can increase the risk of cancer. PLEASE NOTE: Turn around time for this analyte is 7-10 business days.Ĭesium is a radioactive metal that is liquid at or near room temperature. One of its most important uses is in the ‘caesium clock’ (atomic clock). They are also used to make special optical glass, as a catalyst promoter, in vacuum tubes and in radiation monitoring equipment. This reaction is so fast, that if you tried pouring water into a test tube containing caesium (don't do it), the glass container would shatter all over the place. The most common use for caesium compounds is as a drilling fluid. When caesium makes contact with water, it reacts very rapidly, and forms a colourless solution of caesium hydroxide (CsOH) and hydrogen gas (H2). The invention provides a preparation method of a filter medium for removing radioactive cobalt and cesium in water. It has an atomic number of 87 and an atomic mass of 223. It is a soft, silvery-golden alkali metal with a melting point of 28.5 ☌, which makes it one of only five elemental metals that are liquid at or near room temperature. Never seen before Francium dropped in waterFrancium is the 6th alkali metal. Caesium is a chemical element with the symbol Cs and atomic number 55.
