Vladimir Peskov and Antonino Zichichi, one of the members of CERN and the Centro Enrico Fermi in Rome, have designed a fire detection device that, they said, is a thousand times more sensitive than the most sensitive detector currently on sale. The device detects ultraviolet rays emitted by fires. To avoid confusion with those emitted by the Sun, that is, to ensure that the rays are emitted by a fire, the device has been able to detect ultraviolet rays of 185 nm of wavelength, since the Sun emits them but before reaching the terrestrial surface they are absorbed by the ozone layer.
