This animal study exposed adult male C57BL/6 mice to a 4.9 GHz radiofrequency field for three weeks (1 hour/day) and compared them with a sham group. The abstract reports altered fecal microbiome composition with reduced diversity in the RF group, along with 258 significantly differentially abundant fecal…

This qualitative exploratory study examined affective reactions and perceived RF-EMF exposure in everyday mobile phone and base-station situations in the context of the 5G rollout in Germany. Participants expressed more negative associations with base stations than with mobile phones, though RF-EMF exposure was only…

This exposure assessment measured in situ smartphone uplink duty cycles for 4G LTE and 5G NR across six voice, video, and data use cases. Measurements were taken at ten positions near a 4G and 5G base-station site in Belgium. Reported duty cycles varied by application, with some use cases showing low-to-moderate duty…

This commentary critiques a prior paper claiming that Brillouin precursors from 5G NR and other cellular systems could cause tissue damage deeper than the carrier-frequency penetration depth. It states that the original Brillouin precursor theory was based on nanosecond ultrawide-band RF pulses in water and that this…

This animal study examined daily perinatal 5G EMF exposure in rats at the ICNIRP whole-body public exposure limit (maternal SAR 0.07 W/kg) from gestational day 8 to post-natal day 21. The authors report a 1-day delay in incisor eruption in both sexes and sex-dependent changes in stereotyped behavior in the open field…

This study describes a planned and initial experiment assessing RF radiation from user devices in frequency bands common to 4G/5G communications on Butter Bean seed germination and subsequent growth. The setup considered uplink/downlink radiation patterns and exposure-related factors such as frequency and distance.…

This article is a comment on a previously published correlation study assessing whether RF-EMF exposure relates to survey-based health indicators such as sleep, headache, and fatigue. The authors state they performed a detailed analysis of the original study and offer clarifications. The abstract does not provide the…

Jan 1, 2021
This paper presents an RF-EMF exposure assessment combining measurements and deterministic 3D ray-launching simulations in a large indoor public library with high node density. It considers mmWave 5G FR2 at 28 GHz and Wi-Fi 802.11ay at 60 GHz under realistic operation conditions with varying user distributions. The…
