The fifth-generation new radio cellular network will be rolled out within the next few years. Several assessment methods of human exposure to electromagnetic fields transmitted by fifth-generation new radio base stations are discussed. Currently no method exists that allows extrapolation to the maximum theoretical exposure. Thus two new extrapolation methods are proposed. A 95th percentile exposure can be derived from the maximum theoretical exposure by an agreed-upon reduction factor if a more realistic exposure assessment is required.

Directive 2013/35/EU of the European Parliament and Council recommends the weighted peak method for assessing non-thermal effects of low frequency (LF) electric and magnetic fields. This article shows that this method is very practical and user friendly and is absolutely reliable to lead to correct results when applied in the time domain. The method can be used without limitations for any field profile and emulates the underlying physical and biological effects significantly better than all other presently known methods. For this reason, this method is described and recommended in many technical standards for assessing the non-thermal effects of electromagnetic fields and is recognized by the international scientific community. The disadvantages of competing methods are demonstrated. Some technical aspects of real measurement systems are also examined.

Der Einfluß des menschlichen Körpers auf die elektrischen und magnetischen Feldkomponenten in unmittelbarer Nähe des KörpersAbstract Warning devices and meters are necessary for personal safety in radio frequency (RF) and microwave electromagnetic fields. The relevant standards and guidelines dictate that the respective field strength must be displayed that would exist if no one were present in the field. Accordingly, we must first determine to what extent the presence of a human body influences the individual electric and magnetic field components. Extensive computer-based computations were performed to this end. With the results obtained, a field strength meter for personal safety applications was developed which exhibits significant advantages over previous solutions. ÜbersichtFür den Personenschutz in hochfrequenten elektromagnetischen Feldern sind Warn-und Meßgeräte notwendig. Die entsprechenden Normen und Richtlinien fordern, daß diejenige Feldstarke angezeigt wird, die ohne Anwesenheit der betreffenden Person herrschen würde. Damit ist zunächst zu klären, in welchem Umfang die einzelnen elektrischen und magnetischen Feldkomponenten durch die Anwesenheit des menschlichen Körpers beeinflußt werden. Hierzu wurden umfangreiche Computerberechnungen durchgeführt. Unter Berücksichtigung der dabei erzielten Ergebnisse konnte ein Feldstärkemeßgerät für den Personenschlitz entwickelt werden, das erhebliche Vorteile gegenüber bisherigen Lösungen aufweist.Für die Dokumentation Feldstärkenmeßgerät / Elektromagnetische Umgebungskompatibilität / Meßgenauigkeit / menschPcher Körper
