2-5G electromagnetic field biological effect by oxidative stress investigation on animals: exposure and aftereffects

The fifth generation (5G) cellular networks development with operation various previous cellular standards indicates a change of electromagnetic background by new sources, and has a human health risk factor. The purpose of the research was to evaluate the electromagnetic field biological effects of monthly multi-frequency electromagnetic field exposure from 2-5G cellular communication systems on some indicators of oxidative stress in the blood of rats and the aftereffect state. The first group of animals exposed by electromagnetic field from 2-4G base stations (central frequencies 1.8; 2.1 and 2.6 GHz), second - 5G with central frequencies 3.5; 28 and 37 GHz. The pro-oxidant and antioxidant components concentrations (diene conjugates, ketodienes) and catalase in blood rats were investigate. Results showed the possibility of pro-oxidant and antioxidant components concentrations imbalance which is a consequence of the oxidation processes activation and an increase body’s adaptive mechanisms, in particular, antioxidant protection. The electromagnetic field biological effect of 5G NR/IMT-2020 exposed is unstable, as opposed to the consequences of 2-4G electromagnetic field exposure.
