Sensors normally used to detect nuclear weapons tests have picked up an unexplained rise in radiation coming from a region which includes the Russian city of St Petersburg. Sensors normally used to detect nuclear weapons tests have picked up an unexplained rise in radiation coming from a region which includes the Russian city of St PetersburgA spokesman for the organisation the radiation was 'certainly' produced from nuclear fission - the process used to generate nuclear power. The monitoring stations ordinarily detect nuclear weapons tests by using seismic, hydroacoustic and other technology. CTBTO chief Lassina Zerbo said in a tweet which included a map of the affected region that the levels detected were higher than usual but 'not harmful for human health.' Nuclear fission refers to the atomic chain reaction that generates heat in nuclear reactors used in nuclear power stations.
