A study published in Bioengineering (March 2025) by an international team involving researchers from the Sorbonne University and CNRS (France), Naresuan University (Thailand), Xavier University (USA) and the University of Surrey (UK) reveals changes in reactive oxygen species (ROS) in human cells exposed to 1.8 GHz (3G) radiofrequencies, at levels up to 100,000 times lower than current regulatory limits. This scientific work provides new experimental evidence of non-thermal effects, challenging the regulatory paradigm based exclusively on tissue heating (thermal effects) recommended by ICNIRP (International Commission on Non-Ionizing Radiation Protection).

Key points of this study on non-thermal effects

• Rigorous methodology: Shielded exposure system with thermal control (±0.1°C) and in situ dosimetry, eliminating artifacts from previous studies.
• Biphasic effects: Modulation of genes (KIAA, GPX1, SOD2) following a U-shaped curve, with peaks at infinitesimal powers (0.66 µW/m²).
• Identified mechanism: ROS-induced oxidative stress, implicated in neurodegenerative and cancer pathologies.

The authors conclude their findings as follows:

“We believe that this method can help provide a guideline for greater reliability and reproducibility of research results between laboratories, and thus help resolve the current controversy over the underlying mechanisms and outcomes of radiofrequency exposure in the general population.”
