Assessment of measurement uncertainty for verification of compliance with guidelines for human exposure to EMFs from AM broadcasting transmitters

Abstract

In this paper we analyze the uncertainty in measurement when assessing the exposure levels of the general public to RF electromagnetic fields (EMFs) from AM broadcasting transmitters. The purpose of measurement was to evaluate whether human exposure levels are in compliance (or not) with protection guidelines. Six sources of uncertainty were selected, and in order to allow for the propagation characteristics of the middle frequency range, the uncertainties of both the electric and magnetic fields were evaluated. Estimated uncertainties were identical to ±2.34 dB.
