This anti static storm protection towers are constructed with thorium 90, working the same method that polonium 210 works on small discs devices at some industries, like paper, wood, or pyrotechnics, (one of the reasons there's explosions accidents times to times, is bcz either the failure, either the industries are not obligèe of the equipment) ; 4 of these towers were stolen at North Ireland, in 2017. If not properly working, on any storm, the airport would be in danger of airplanes collision, and tower control electronic failure.
