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
Radiation effects from the Fukushima Daiichi nuclear disaster non-profit Radiation Effects Research Foundation said that people should not overreact, because there are no reports known of health problems with these levels of radiation. On 31 October 2011 a scientist from the Worcester Polytechnic Institute, Marco Kaltofen, presented his findings on the releases of radioactive isotopes from the Fukushima accidents at the annual meeting of the American Public Health Association (APHA). Airborne dust contaminated with radioactive particles was released from the reactors into the air. This dust was found in Japanese car filters: they contained caesium-134 and caesium-137, and cobalt at levels as high as 3 nCi total activity
