Due to this, nausea, vomiting, and bleeding may occur. Radioactivity: If a person comes in contact with a radioactive isotope of caesium then cell-damage may occur.

Its advantages are that it has a half-life of 30 years and it has barium-137 as a stable end product. Nuclear application: Caesium-137 is used as a gamma emitter in industrial applications.Molecular Biology: High density caesium compound solutions such as caesium chloride, caesium sulfate, etc are used in density gradient ultracentrifugation.Atomic-clocks: They use the electromagnetic transition in the hyperfine structure of caesium-133 atoms as the reference point.It also helps bring rock cuttings to the surface and to maintain pressure on the formation during drilling of the well. The main function of drilling fluids is to lubricate drill bits. Petroleum exploration: The largest use of caesium is as a drilling fluid for extractive oil and petroleum industry. In larger amounts, Cs-137 is used in medical radiation therapy devices for treating cancer in industrial gauges that detect the flow of liquid through pipes. Relevance in Chemical and Related Industries Cesium is also not really 'state of the art' strontium clocks are starting to outpace it, although maybe not for commercial purposes just yet. Rubidium has also been used in commercially available atomic clocks. This precipitated double salt is then decomposed and the water is evaporated to obtain pure caesium chloride. Cesium is not the only material used in atomic clocks. The grounded ore is dissolved in strong acids which leads to formation of caesium double salts. The caesium is extracted from pollucite mainly by acid digestion. The ore is crushed, hand-sorted, and then grounded. Caesium forms variety of compounds including variety of halides and oxides.įrom Pollucite: The mining and refining of pollucite is a selective process hence it is done on a smaller scale.Caesium can only be handled under inert atmosphere.

It even reacts with ice whose temperature is as low as -116☌. It reacts explosively with water even at low temperatures.

Caesium is pyrophyric in nature, which means that it spontaneously ignites in air.

Among them, the only stable isotope is caesium-139. Caesium (or cesium) is the chemical element with the atomic number 55 on the periodic table.

Caesium is softest among all metals which are solid at room temperature.

The density of caesium is 1900 in S.I.

Caesium is a soft metal which shines in gold colour.

It is a relatively rare element and makes up 3 ppm of Earth’s crust. Caesium is found in minerals pollucite and lepidolite. Cesium is mostly used today in drilling fluids for the oil industry.
