Radioactive Incident Monitoring Network at a central computer based in a DEFRA building in central London. For security reasons, a backup computer is also in operation at a secret location in the UK. The network was set up in 1988 as a response to the Chernobyl disaster in 1986. As well as being of use in an emergency, the stations also serve to record historical data on radiation levels. Radioactive Incident Monitoring Network The Radioactive Incident Monitoring Network (RIMNET) is a network of 91 monitoring stations, used by the Government of the United Kingdom, which records and analyses the level of radioactivity across the
Caesium chloride container which is then enclosed into another steel casing. The sealing is required to protect the salt from moisture. In the laboratory, CsCl can be obtained by treating caesium hydroxide, carbonate, caesium bicarbonate, or caesium sulfide with hydrochloric acid: Caesium chloride is the main precursor to caesium metal by high temperature reduction: A similar reaction – heating CsCl with calcium in vacuum in presence of phosphorus – was first reported in 1905 by the French chemist M. L. Hackspill and is still used industrially. Caesium hydroxide is obtained by electrolysis of aqueous caesium chloride solution: Caesium chloride is widely used
