Early research found no characteristic visceral lesions and no pathological change in reproduction in mice and rats exposed to non-heating, pulse-modulated ultra-short waves.
Plain English Summary
This French research study examined internal organs and reproduction in mice and rats exposed to pulse-modulated ultra-short waves at 3105 MHz, with modulation chosen to avoid heating. It reported no characteristic visceral lesions (tissue damage to internal organs) and no pathological change in reproduction. The only finding noted was slightly enlarged, congested spleens, which the authors link to a possible excitation of the reticulo-histiocytic system.
Why This Matters
This study represents early research into the biological effects of radiofrequency radiation on internal organs. The focus on visceral lesions is notable because it examined tissue directly rather than just functional changes. What makes this research noteworthy is its investigation of reproductive effects alongside general organ effects, at a time when most researchers attributed biological disturbances to the heating effect of ultra-short waves.
The study found no characteristic visceral lesions in mice and rats exposed to 3105 MHz pulse-modulated waves, with modulation chosen to avoid heating. The heart, lungs, kidneys, adrenals and pancreas looked normal, the spleens were slightly hypertrophic and congested, and the genital organs showed no morphological alteration. Thermal lesions, such as coagulation necrosis of the liver and lysis of the intestinal mucosa, appeared only when the animals could not dissipate the heat.
Exposure Details
- Power Density
- 8 mW/cm2
- Exposure Duration
- 190 heures, 300 heures, 450 heures pour les études sur les organes; 207 heures, 190 heures, 306 heures pour les études sur la reproduction
Exposure Context
This study used 8 mW/cm2 for radio frequency:
- 800Mx above the Building Biology guideline of 0.1 μW/m²
- 13.3Mx above the BioInitiative Report recommendation of 0.0006 μW/cm²
Building Biology guidelines are practitioner-based limits from real-world assessments. BioInitiative Report recommendations are based on peer-reviewed science. Check Your Exposure to compare your own measurements.
Where This Falls on the Concern Scale
Study Details
Étudier les effets des ondes ultra-courtes sur la reproduction et les organes viscéraux de souris et rats, en évitant l'effet thermogéne par une modulation appropriée.

Lorsque les animaux sont mis dans des conditions telles qu'ils peuvent éliminer physiologiquement la chaleur due à la transformation de l'énergie électromagnétique dans leur organisme, les ondes ultra-courtes n'ont aucune action ni sur l'aspect des animaux, ni sur leur comportement, ni sur les organes. Le seul fait à retenir est une excitation possible du Système Réticulo-Histiocytaire. L'exposition des rats et des souris aux ondes ultra-courtes n'a entrainé aucune modification pathologique de la physiologie de la reproduction. Les examens anatomopathologiques des gonades ont toujours révélé un aspect normal.
