Nuclear 'accident' sends radioactive pollution over Europe
A cloud of radioactive pollution spread over Europe after a possible "accident" at a nuclear facility in Russia or Kazakhstan, French nuclear safety officials confirmed on Friday.
France's nuclear safety institute, IRSN, picked up faint traces of ruthenium 106, a radioactive nuclide that is produced when atoms are split in a nuclear reactor and which does not occur naturally, in three of its 40 monitoring stations late September.
