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.
Highlights
The number of mobile phone users has been increasing rapidly with approximately 7.68 billion by 2017 (Smith-Roe et al 2020)
Most relevant researches have been based on epidemiological studies or cultured cells, while evidence from animal studies is preferred to draw more reliable conclusions
Results from these studies suggest that cell phone radiation could lead to DNA damage (Sharma et al 2019; Smith-Roe et al 2020; Alkis, Akdag, et al 2019; Alkis, Bilgin, et al 2019) and these findings are in line with our results
Summary
The number of mobile phone users has been increasing rapidly with approximately 7.68 billion by 2017 (Smith-Roe et al 2020). Results based on cultured cells suggest that cell phone use may involve DNA damage, ERK activation or repetitive DNA transcription (Diem et al 2005; Friedman et al 2007; Del Re et al 2019). Rodents have been used as animal models to study the potential adverse effects of mobile phone radiation on human health (Ghoneim and Arafat 2016; Wyde et al 2016). Elevated levels of oxidative stress and DNA damage have been reported in the rat brain when they were exposed to radiation (Alkis, Bilgin, et al 2019). DNA damage was observed in the brain tissues when the animals were exposed to cell phone radiation
