Lågfrekventa elektriska och magnetiska fält

Pulserande fält som alstras av avböjningsenheten. Dessa är föremål för ökande uppmärksamhet, särskilt av myndigheterna, affärsvärlden och pressen. Fastän det inte finns några vetenskapliga belägg för att strålning från monitorer är skadlig, har stora resurser satts in för att minska strålningen enligt principen bättre att föregå än föregås. För närvarande är två områden intressanta: mycket lågfrekventa (VLF) elektriska och magnetiska fält från 2 kHz till 400 kHz, och extremt lågfrekventa fält (ELF) från 5 Hz till 2 kHz.
