Survey of ELF Electric and Magnetic Field Levels – One Example for Determining of the Measurement Uncertainty

Abstract

Unwanted levels of electric, magnetic and electromagnetic fields (EMF) in the environment have become omnipresent. In this sense, the people are requesting information about levels of exposure to time-varying electric and magnetic fields in living spaces. For low-frequency range (0 Hz – 100 kHz), attention is focused on survey around the systems for transmission, distribution and use of electrical energy. In the past ten years, the author of this paper has performed in-situ broadband measurements of ELF (30 Hz – 300 Hz) electric and magnetic field levels in the environment in over 35
