Effects of Extremely Low Frequency Magnetic Field Exposure (50 Hz, 200 µT) on Cell Viability, DNA Damage and Micronucleus Formation of Human Skin Cells

Vivian Meyer, Karen Drees, Isabel Alexandra Gronau, Alexander Lerchl

Both everyday electrical devices and high voltage transmission lines produce electric and magnetic fields with a frequency of 50 Hz in Europe and most other countries. Although several studies have already been investigating the effects of extremely low frequency magnetic field (ELF-MF) …

5G-exposed human skin cells do not respond with altered gene expression and methylation profiles

Jyoti Jyoti, Isabel Gronau, Eda Cakir, Marc-Thorsten Hütt et autres

Due to the ever-increasing wirelessly transmitted data, the development of new transmission standards and higher frequencies in the 5G band is required. Despite basic biophysical considerations that argue against health effects, there is public concern about this technology. Because the skin penetration …

Design and Dosimetric Characterization of a Broadband Exposure Facility for In Vitro Experiments in the Frequency Range 18–40.5 GHz

Gernot Schmid, René Hirtl, Isabel Gronau, Vivian Meyer et autres

A novel exposure facility for exposing cell monolayers to centimeter and millimeter waves (18–40.5 GHz) used by future 5G mobile communication technology and similar applications has been developed. A detailed dosimetric characterization of the apparatus for frequencies of 27 and 40.5 GHz …

Spermatogenesis in the Roborovski hamster (Phodopus roborovskii) and the Chinese hamster (Cricetulus griseus)

Vivian Meyer, Melanie Klose, Alexander Lerchl

BACKGROUND: Spermatogenesis is an elaborately organized and tightly regulated differentiation process. The spermatogenesis duration is stable within a certain species but highly variable between species of the same family. OBJECTIVES: In this study, the spermatogenesis duration of the Roborovski hamster was measured …

Effects of Long‐Term Exposure of Intermediate Frequency Magnetic Fields (20 kHz, 360 µT) on the Development, Pathological Findings, and Behavior of Female Mice

Alexander Lerchl, Karen Drees, Isabel Gronau, Dirk Fischer et autres

The use of magnetic fields in the intermediate-frequency (IF) range to wirelessly charge electric cars with power transfer in the kilowatt range has become increasingly widespread, leading to unavoidable stray fields in the microtesla range. Only a handful of studies have assessed …

No Increased DNA Damage Observed in the Brain, Liver, and Lung of Fetal Mice Treated With Ethylnitrosourea and Exposed to UMTS Radiofrequency Electromagnetic Fields

Alexander Lerchl, Melanie Klose, Karen Drees

The widespread use of mobile phones and Wi-Fi-based communication devices makes exposure to radiofrequency electromagnetic fields (RF-EMF) unavoidable. Previous experiments have revealed the tumor-promoting effects of non-ionizing RF-EMF in adult carcinogen-treated mice in utero. To extend these investigations, we tested whether these …

Regulation of Mammalian Pineal Melatonin Production by the Electromagnetic Spectrum

Russel Joseph Reiter, Alexander Lerchl

The circadian production of melatonin and rhythms of associated enzymes in the pineal gland of mammals have long been known to be regulated by the prevailing light-dark environment. The current survey is concerned with the 24-h pattern of melatonin production in the …

Effects of Early-Onset Radiofrequency Electromagnetic Field Exposure (GSM 900 MHz) on Behavior and Memory in Rats

Melanie Klose, Karen Grote, Oliver Spathmann, Joachim R. Streckert et autres

Female Wistar rats, from an age of 14 days to 19 months, were exposed in the head region for 2 h per day, 5 days per week, to a GSM-modulated 900 MHz radiofrequency electromagnetic field (RF-EMF). The average specific absorption rates (SAR) …

Noninvasive Assessment of Metabolic Effects of Exposure to 900 MHz Electromagnetic Fields on Djungarian Hamsters (Phodopus sungorus)

Kirstin Taberski, Melanie Klose, Karen Grote, Abdessamad El Ouardi et autres

Sixteen male Djungarian hamsters, serving as their own controls, were individually exposed to RF-EMF (900 MHz, GSM modulation) at 0 (sham), 0.08, 0.4 or 4 W/kg specific absorption rate (SAR) in specially constructed rectangular waveguides. Exposure duration was one week per condition, …
