The story only gets worse. In July 2015, a review of existing studies on radiofrequency radiation (RFR) was published by National Academy of Sciences in Ukraine, Indiana University, and the University of Campinas in Brazil. Based on "93 out of 100 peer-reviewed studies, it concluded that low-intensity RFR [radio-frequency radiation] is an expressive oxidative agent for living cells with a high pathogenic potential, and that oxidative stress induced by RFR exposure should be recognized as one of primary mechanisms of biological activity of this kind of radiation. This explains a range of biological/health effects of low-intensity RFR, which includes both cancer and non-cancer pathologies."
Cellular effects of radiation are basically the same for the different kinds and doses of radiation. The simplest and most direct effect of radiation is cell death. Changes in cellular function can occur at much lower radiation doses than those that cause cell death. Changes can include delays in phases of the mitotic cycle, disrupted cell growth, permeability changes, and changes in motility.
