MECHANISMS OF BIOLOGICAL ACTIVITY OF LOW-INTENSITY RADIOFREQUENCY RADIATION

Abstract:
This review aims to analyze experimental data on biological effects of radiofrequency radiation. Recent experimental data indicate that the low-intensity radiofrequency radiation is able to interact with ions and local charges of molecules, potentially affects cell metabolism, leads to activation of free radical processes, accompanied by activation of peroxide processes, changes activity of antioxidant defense enzymes, and causes oxidative damage of DNA. This data allow to classify low-intensity radiofrequency radiation as an oxidative stress-factor for living cell.
Keywords: free radicals, oxidative stress, radiofrequency radiation, reactive oxygen species, DNA damage, apoptosis.
