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
Timeline of the Fukushima Daiichi nuclear disaster of a new leak of radioactive water into the sea. The Itabashi Ward Office announces that a concentration of caesium-134 at 2,700 becquerels per kilogram – in excess of the government's provisional limit – was detected in tea processed from leaves picked on 9 May in Tokyo. The water decontamination and water recycling systems are now both functional. 100% recycled water is now used for reactor cooling, and no additional volume of contaminated water is being generated. Radioactive caesium-137 is found in Tokyo's tap water for the first time since April. Radioactive caesium from Fukushima was expected to enter the
