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
Fukushima Daiichi nuclear disaster experimental agricultural research fields around the affected area) has noted that "the fallout was found at the surface of anything exposed to air at the time of the accident. The main radioactive nuclides are now caesium-137 and caesium-134", but these radioactive compounds have not dispersed much from the point where they landed at the time of the explosion, "which was very difficult to estimate from our understanding of the chemical behavior of cesium". In February 2018, Japan renewed the export of fish caught off Fukushima's nearshore zone. According to prefecture officials, no seafood had been found with radiation levels exceeding
