  • 2010:20 Lågfrekventa magnetfält i olika färdmedel – en studie baserad på mätningar från åren 1993-2010

    för lågfrekventa magnetfält i bussar, bilar, fjärrtåg, pendeltåg, spårvagnar, tunnelbanetåg, fartyg och flygplan. Mätningarna har gjorts på slumpvis valda platser där passagerare uppehåller sig vilket gör ... De högsta värdena uppmättes i tåg. Medelvärdet i tåg var omkring 2-27 mikrotesla beroende på tåg- och vagnstyp. I pendeltåg kunde magnetfält på upp till 80 mikrotesla mätas vid enstaka tillfällen. Den...
