Plain English Summary
Researchers exposed male Wistar rats to radio frequency radiation at 1800 MHz with a specific absorption rate of 0.95 to 3.9 W/kg for 40 or 60 days continuously. At 40 days, electromagnetic radiation failed to induce any significant alterations. At 60 days of exposure, various attributes evaluated decreased, including decreases in NADPH and ascorbate-linked lipid peroxidation along with diminution in enzymatic antioxidative defense systems and decreased glucose residue.
Why This Matters
The study aimed to investigate the oxidative stress-inducing potential of non-thermal electromagnetic fields in rats. Male Wistar rats were exposed to an electrical field intensity of 2.3 ± 0.82 µV/m. Exposure was delivered in three forms: continuous waves, or modulated at 900 MHz, or modulated GSM-nonDTX. Control animals were located more than 300 m from the base station, while sham control animals were kept near a non-functional base station in similar environmental conditions. The researchers noted that the biochemical changes observed may be associated with prolonged exposure to electromagnetic fields and their relationship to the activity of the antioxidant system in rats.
