Electromagnetic fields (EMF) in electric vehicles

Funding: Swiss Federal Office of Energy SFOE Energy Research and Cleantech

In order to decarbonize mobility, more and more battery-powered electric vehicles are being put into operation. Electric, magnetic and electromagnetic fields (EMF) are generated in and around the vehicles by the electrical components of the drive, by charging the battery and by other diverse electronic systems used in modern vehicles. The aim of this project was to carry out measurements on a selection of electric vehicles to assess whether the additional EMF emissions from the electric drive and the associated components are to be considered a critical health risk and whether further in-depth clarifications are necessary.

Scientific literature monitoring “EMF of electricity technologies”, status report 2022

Funding: Swiss Federal Office of Energy SFOE Energy Research

The report compiles scientific literature on low-frequency electromagnetic fields (LF-EMF; in particular 50/60 Hz and 16.7 Hz) and is an update of the synthesis report last published in 2017. The focus is on biological and health effects. In addition, the social science research status on perception, communication and acceptance issues as well as selected questions in the field of electromagnetic compatibility (EMC) of some newer, low-frequency technologies are also discussed. The report also addresses questions of exposure assessment and the low-frequency exposures encountered in everyday life and at the workplace. With regard to possible health effects, the publications listed in the 2017 report are mentioned first and then the more recent literature published since then up to mid-2022 is commented on.

Health Effects of AC/DC Powerlines - A Literature Review

Funding: Ministry of Environment, Energy, Food and Forests; Rhineland-Palatinate

This literature review describes the current state of knwledge concerning potential health effects of powerlines, expecially of HVAC/DC transmission lines. All emissions are scrutinized, i.e. magnetic fields, electric fields, ion current, noise, aersols, and air pollutants.

Cosmetics, Wellness and Health – EMF applications at home and in beauty and wellness salons

Funding: German Ministry for Radiation Protection (BfS)

The project "Cosmetics, Wellness and Health – EMF applications at home and in beauty and wellness salons" systematically collects and characterises EMF applications, including ultrasound, used in houdholds and in commercial studios. Exposures will be assessed and potential health impacts, as far as they are existing and registered, will be documented.

Research Activities and Insights into Potential Health Impacts of RF EMF

Funding: Office for Technology Assessment of the German Bundestag (TAB)

The goal of this study is to give TAB an overview over the research activities and insights into potential health impacts from RF EMF - especially mobile communication frequecies. The time window of interest covers the last 10 years, roughly (termination of the German Research Programme on Mobile Communication in 2008/9).  Presentation of the selected important activities in Germany, Europe and outside Europe (national and international programmes). Synthesis of insights, identification of reseearch gaps, recommendations.

Diverging Assessments of Health Risks from Mobile Technologies

Funding: BfS (German Ministry for Radiation Protection)

Principal applicant: Stiftung Risiko-Dialog St. Gallen. The project will analyse the health risk assessments of the main institutional voices in Germany. First, the main scientific "facts" (consesual as well as controversial) dominating the public debate are listed. Second, key institutional players in the German public arena are indentified, and their risk assessments are analysed. Third, important factors influencing risk perception and risk evaluation are derived from literature. Fourth, the institutional risk assessments are compared against a generic framework consisting of, among others, criteria for selecting and weighing evidence. Finally, the results are presented in a way that allows readers to quickly identify conflicting institutional assessments in terms of both, issues as well as evaluation criteria.

Energy efficiency of and EMF exposure to integrated wireless power transfer devices

Funding: SFOE, FOEN

The project assesses energy efficiency and electromagnetic radiation of wireless charging stations for elec-tronic items by means of empirical measurements and numerical characterisations (different product designs – single coils, arrays; different handling – exact positioning, other). Energy consumption will be compared with conventional charging, EMF emissions will be related to human exposure guidelines. The report ends with recommendations.

Scientific Review „ELF Electric and Magnetic Fields“

Funding: SFOE

This report comments on the scientific literature about extremely low frequency (ELF) electric and magnetic fields, i.e. 50 Hz (power grid) and 16.7 Hz (railway grid). The main focus lies on biological and health studies. Research about social science and engineering / electromagnetic compatibility (EMC) issues is also covered, however, in a less comprehensive manner. Concerning health, the majority of the discussed peer reviewed literature pertains to epidemiology and human provocation experiments, published since 2010 approximately.

Literature Survey on Stray Voltage

Funding: Swissgrid

In the scientific literature the topic "stray voltage" is quite well covered by engineering papers focusing on the various technical aspects of the issue. Biological and health topics are less often addressed. The report will inform about conceptual and technical issues of "stray voltage" and summarise the exposure and effect studies dealing with farms and cattle on one hand, homes and potential human health Impacts on the other hand. The focus is on 50/60 Hz fields.
