Distribution of High-Frequency Electromagnetic Fields on the Basis of Total Exposure Quotients

Extensive non-ionizing high-frequency electromagnetic field (HF EMF) measurements were carried out in Republic of Croatia during 2018. Measurements of electric field strength on 812 locations were analysed. This paper focuses on distribution of HF EMF given on the basis of ICNIRP's total exposure quotients (TEQ). Main objective is to establish which HF EMF sources affect TEQ values the most and to create classification of human exposure to HF EMF in respect to TEQ. Collocated HF EMF sources were also analysed, because they dominantly affect TEQ values on every point of investigation. There is an ongoing need for occasional controlled measurements of HF EMF, because on some points of investigation values of TEQ can exceed the established criteria and can have potentially negative effect on human health. Those locations are usually collocated with different HF EMF sources, which can be found on top of buildings or on one or more masts built very close to one another.
