Synthesis of 14 curated RF-EMF papers: high-certainty animal cancer signals (male rat heart schwannomas, glioma), high-certainty male fertility impacts, and strong oxidative-stress mechanisms below heating thresholds—…

Non‑Thermal RF Biological Effects Are Documented—Thermal‑Only Safety Limits Are Not a Complete Health Standard

Research Effect Synthesis Mar 1, 2026

Synthesis of 11 curated studies finds consistent evidence for non-thermal RF biological effects (oxidative stress, fertility impacts, and animal cancer signals) plus higher pediatric absorption—showing thermal-only RF…

Trends in Malignant and Benign Brain Tumor Incidence and Mobile Phone Use in the U.S. (2000-2021): A SEER-Based Study

This SEER-based ecological study examined U.S. trends (2000–2021) in malignant and benign brain tumor incidence and compared them with national mobile phone subscription trends. Malignant brain tumor incidence in adolescents and adults declined slightly, while benign brain tumor incidence increased over time;…

5G Radio-Frequency-Electromagnetic-Field Effects on the Human Sleep Electroencephalogram: A Randomized Controlled Study in CACNA1C Genotyped Volunteers

Research RF Safe Research Library Jan 1, 2025

This randomized, double-blind, sham-controlled study tested whether CACNA1C rs7304986 genotype modifies sleep EEG responses to 5G RF-EMF exposure. The authors report a genotype-by-exposure interaction, with 3.6 GHz exposure in T/C carriers associated with a faster NREM sleep spindle center frequency versus sham. The…

Epidemiological criteria for causation applied to human health harms from RF-EMF exposure: Bradford Hill revisited

Research RF Safe Research Library Jan 1, 2025

This paper is a commentary reviewing how Bradford Hill’s epidemiological criteria can be applied to multidisciplinary evidence on RF-EMF exposure and adverse health effects. It reports that systematic reviews and meta-analyses in this area often reach substantially different conclusions, and argues that key…

Use of Mobile and Cordless Phones and the Association with Prostate Cancer

Research RF Safe Research Library Jan 1, 2025

This pooled analysis of two prior human studies reports increased odds of prostate cancer associated with mobile phone use, with higher estimates for longer latency and higher cumulative hours. Cordless phone use is reported to show increased risk but not statistically significant overall, with one mid-range…

Effect of ELF-EMF on cognitive functions, analgesia, and oxidative stress in rats with PTZ-induced epilepsy.

Research RF Safe Research Library Jan 1, 2025

This animal study tested repeated 50 Hz, 5 mT ELF-EMF exposure in rats with and without PTZ-induced epilepsy. The authors report changes in learning/short-term memory in the EMF+PTZ group versus PTZ alone and increased analgesia latency in EMF-exposed groups. PTZ increased oxidative stress (TOS) in brain regions, and…

Evidences of the (400 MHz - 3 GHz) radiofrequency electromagnetic field influence on brain tumor induction.

Research RF Safe Research Library Jan 1, 2022

This review discusses whether radiofrequency electromagnetic fields (400 MHz–3 GHz), particularly from mobile phones, influence brain tumor induction. The abstract describes epidemiological evidence as supporting a causal association, highlighting statistically significant ipsilateral tumor findings. It also claims…

Comparing the Effects of Long-term Exposure to Extremely Low-frequency Electromagnetic Fields With Different Values on Learning, Memory, Anxiety, and β-amyloid Deposition in Adult Rats.

Research RF Safe Research Library Jan 1, 2021

This animal study exposed adult male rats to 50 Hz ELF-EMF at 1, 100, 500, or 2000 μT for 1 hour/day over two months and assessed behavior and brain markers. The authors report increased memory retention (higher step-through latency) alongside increased anxiety-like behavior (reduced open-arm entries), particularly…

Effect of acute exposure to radiofrequency electromagnetic fields emitted by a mobile phone (GSM 900 MHz) on electrodermal responsiveness in healthy human.

Research RF Safe Research Library Jan 1, 2018

This study examined whether acute GSM 900 MHz mobile phone exposure affects electrodermal activity responses to auditory stimuli in 28 young volunteers. The authors report no exposure-related changes in SCR latency, amplitude, integral, or number of responses. Session differences in skin conductance/tonic…

Electromagnetic field exposure (50 Hz) impairs response to noxious heat in American cockroach.

Research RF Safe Research Library Jan 1, 2018

This animal study examined whether 50 Hz electromagnetic field exposure (7 mT) affects heat-escape behavior and oxidative balance in American cockroaches. The authors report increased latency to escape from noxious heat after 24 h, 72 h, and 7 days of exposure. Biomarkers suggested oxidative stress, with elevated…

Does acute radio-frequency electromagnetic field exposure affect visual event-related potentials in healthy adults?

Research RF Safe Research Library Jan 1, 2018

This double-blind, randomized, counterbalanced study tested whether acute GSM-like 920 MHz RF-EMF exposure affects visual event-related potentials in 36 healthy adults. Compared with sham, exposure was associated with reduced P1 amplitude and increased anterior N1 latency, with no effects on other ERP measures. The…

Decreased survival of glioma patients with astrocytoma grade IV (glioblastoma multiforme) associated with long-term use of mobile and cordless phones

Research RF Safe Research Library Oct 16, 2014

This analysis examined survival among 1678 glioma patients from two case-control study periods (1997–2003 and 2007–2009) in relation to wireless phone use. In the >20 years latency group, the authors report increased hazard ratios for glioma overall and for astrocytoma grade IV (glioblastoma multiforme), with hazard…

Assessment of auditory evoked potential in long-term mobile phone users.

Research RF Safe Research Library Jan 1, 2014

This cross-sectional study assessed auditory brainstem responses in 173 long-term mobile phone users aged about 17–39 years. The authors report significant differences in ABR wave and interpeak latencies across age groups, with prolonged average wave I–V latencies in the 20–29 year group. They interpret the latency…
