When the exposure lasts a long time people may even lose consciousness. Due to this, effects such as nausea, vomiting, diarrhoea and bleeding may occur. When contact with radioactive cesium occurs, which is highly unlikely, a person can experience cell damage due to radiation of the cesium particles. It is not very likely that people experience health effects that can be related to cesium itself. People that work in the nuclear power industry may be exposed to higher levels of cesium, but many precautionary measurements can be taken to prevent this. These accidents have not occurred since the Chernobyl disaster in 1986. The amount of cesium in foods and drinks depends upon the emission of radioactive cesium through nuclear power plants, mainly through accidents. In air the levels of cesium are generally low, but radioactive cesium has been detected at some level in surface water and in many types of foods. Humans may be exposed to cesium by breathing, drinking or eating. World production of cesium compounds is just 20 tonnes per year, coming mainly from the Bernic lake (Canada) with a little from Zimbabwe and South-West Africa. Few cesium mineral are know, pollucite is the main: they are silicate magmas cooled from granites. Cesium is used in atomic clocks and more recently in ion propulsion systems.Īlthough cesium is much less abundant than the other alkali metals, it is still more common than elements like arsenic, iodine and uranium. The chloride is used in photoelectric cells, in optical instruments, and in increasing the sensitivity of electron tubes. Cesium salts are used to strenght various types of glass. Cesium is sometimes used to remove traces of oxygen from the vacuum tubes and from light bulbs. Cesium nitrate is used to make optical glasses. Cesium metal oxidized rapidly when exposed to the air and can form the dangerous superoxide on its surface.Ĭesium is used in industry as a catalyst promoter, boosting the performance of other metal oxides in the capacity and for the hydrogenation of organic compounds. Cesium reacts with the halogens to form a fluoride, chloride, bromide, and iodide. Cesium hydroxide is a strong base and attacks glass. Cesium reacts explosively with cold water, and reacts with ice at temperatures above -116☌. Cesium, gallium, and mercury are the only three metals that are liquid at or around room temperature. It is the most electropositive and most alkaline element. The metal is characterised by a spectrum containing two bright lines in the blue (accounting for its name).
