Abstract

The toxic effect of mobile phone radiation on rabbit organs Shudong Zhu, Yan Zhu, Hao Li, Doudou Zhang, Dianzheng Zhang. The toxic effect of mobile phone radiation on rabbit organs. All Life. 252-258. 19 May 2020. doi.org Abstract Whether electromagnetic radiation (EMR) emitted from mobile phones is hazardous to human health is largely unknown. We investigated the effects of mobile phone radiation on critical organs in a rabbit model by exposing the animals to mobile phone radiation with sub-thermal specific absorption rate (SAR) of 1.0 and 0.7 W/kg for the head and the body, respectively, for 16 weeks (6 h/day, 6 days/week). There is no apparent change at the organ level. However, H&E staining showed that radiation-exposure significantly increased inflammatory cell infiltration in the liver and the lungs with a lesser degree of myocardial cell cytoplasmic vacuolation. In addition, results from γ-H2AX staining suggest that radiation can also cause DNA damage in the brain. Of note, no apparent activation of Caspase-3 in the organs examined. Our data altogether suggest that mobile phone radiation may be more hazardous to both the liver and the lungs, and less toxic to the brain and heart. tandfonline.com

Main findings

Rabbits exposed to mobile phone radiation at sub-thermal SAR (head 1.0 W/kg; body 0.7 W/kg) for 16 weeks showed no apparent organ-level changes. H&E staining indicated significantly increased inflammatory cell infiltration in liver and lungs and a lesser degree of myocardial cell cytoplasmic vacuolation; γ-H2AX staining suggested DNA damage in the brain, while no apparent Caspase-3 activation was observed in examined organs.

Outcomes measured

  • Organ-level changes
  • Histopathology (H&E): inflammatory cell infiltration (liver, lungs)
  • Myocardial cell cytoplasmic vacuolation
  • DNA damage (γ-H2AX staining) in brain
  • Caspase-3 activation

Limitations

  • Frequency/band of mobile phone radiation not reported in abstract
  • Sample size not reported in abstract
  • Details of exposure setup/control conditions not described in abstract
  • Outcome measures appear limited to selected histology and markers (per abstract)
