The Systems of Radiological Protection for Ionizing and Non-Ionizing Radiation

Research RF Safe Research Library Jan 1, 2026

This article summarizes expert presentations and a panel discussion on radiological protection systems for ionizing and non-ionizing radiation at an international congress. It highlights that ionizing radiation protection is mature and continually revised, while non-ionizing radiation protection lacks a comparable…

The effects of acute and chronic exposure of 3G UMTS 2100 MHz radiofrequency radiation on rat mismatch negativity

Research RF Safe Research Library Jan 1, 2026

This rat study examined acute (1-week) and chronic (10-week) exposure to 2100 MHz radiofrequency radiation (3G UMTS-like) and assessed auditory mismatch negativity (MMN) alongside biochemical and histological brain measures. The abstract reports that acute exposure was associated with reduced MMN-related…

Review of the evidence on the influence of Wi-Fi 2.4 GHz radiation on oxidative stress and its possible relationship with Alzheimer's disease

Research RF Safe Research Library Jan 1, 2025

The review states there is no scientific consensus on whether Wi‑Fi (2.4/5 GHz) contributes to Alzheimer's disease through oxidative stress, and that existing results are mixed and inconclusive. It discusses an indirect analysis linking oxidative-stress-responsive genes after 2.4 GHz exposure with genes associated…

Oxidative stress and testicular damage induced by chronic exposure to 35.5 GHz millimeter wave radiation in male Wistar rats

Research RF Safe Research Library Jan 1, 2025

This randomized controlled animal study examined chronic 35.5 GHz millimeter wave exposure in male Wistar rats (2 hours/day for 60 days) compared with control and sham groups. The exposed group showed reduced sperm count and viability along with testicular histopathological changes. Oxidative stress markers shifted…

Effects of extremely low-frequency electromagnetic field exposure on the skeletal muscle functions in rats.

Research RF Safe Research Library Jan 1, 2020

This rat study examined chronic extremely low-frequency electromagnetic field (ELF-EMF) exposure and diaphragm muscle function and structure. Rats were exposed to 50 Hz, 1.5 mT for 4 hours daily for up to 7 months and assessed with electrophysiological, biochemical, and electron-microscopy measures. The authors…

Effects of Electromagnetic Radiation from Smartphones on Learning Ability and Hippocampal Progenitor Cell Proliferation in Mice.

Research RF Safe Research Library Jan 1, 2016

This mouse study examined chronic smartphone electromagnetic radiation exposure and its effects on spatial working memory and hippocampal progenitor cell proliferation. The authors report no significant differences in Y-maze spontaneous alternation or BrdU-labeled progenitor proliferation after exposure, but…

Effects of 900 MHz electromagnetic field emitted by cellular phones on electrocardiograms of guinea pigs.

Research RF Safe Research Library Jan 1, 2014

This animal study examined whether RF-EMF from cellular phones affects electrocardiograms in guinea pigs. Thirty guinea pigs were randomized to control (no exposure) or RF-EMF exposure (890–915 MHz; SAR 0.95 W/kg) for 12 hours per day over 30 days. The study reports no significant effects on ECG findings under these…

Non-thermal continuous and modulated electromagnetic radiation fields effects on sleep EEG of rats.

Research RF Safe Research Library Jan 1, 2013

This animal study examined whether chronic low-level non-thermal 900 MHz electromagnetic radiation alters rat sleep EEG. Rats were exposed for 1 month (1 h/day) to either unmodulated 900 MHz or 900 MHz modulated at 8 and 16 Hz. The abstract reports that REM sleep measures were more affected than slow wave sleep,…

Ultrastructural alterations and occurrence of apoptosis in developing follicles exposed to low frequency electromagnetic field in rat ovary.

Research RF Safe Research Library Jan 1, 2007

This animal study examined rat ovaries after chronic exposure to a 3 mT low-frequency electromagnetic field for 4 hours per day over 4 months. Using TEM and TUNEL, the authors report ultrastructural alterations in oocytes and more frequent apoptosis-associated changes in granulosa and corona radiata cells versus…
