Abstract
Physical Differences between Man-Made & Cosmic Microwave Electromagnetic Radiation & Exposure Limits, & Radiofrequencies as Generators of Biotoxic Free Radicals Georgiou CD, Kalaitzopoulou E, Skipitari M, Papadea P, Varemmenou A, Gavriil V, Sarantopoulou E, Kollia Z, Cefalas A-C. Physical Differences between Man-Made and Cosmic Microwave Electromagnetic Radiation and Their Exposure Limits, and Radiofrequencies as Generators of Biotoxic Free Radicals. Radiation. 2022; 2(4):285- 302. doi: 10.3390/radiation2040022. Simple Summary There is an inconsistency between the position that radio frequencies are sources of minor thermal effects in cells, tissues and living organisms and the experimental evidence indicating that non-ionising radiation is harmful, even at shallow power density radiation levels. A quantum mechanical survey of the interaction between microwaves and matter points to free radical-associated cytotoxic alterations of biomatter upon microwave irradiation. Abstract The critical arguments for radiofrequency radiation exposure limits are currently based on the principle that radio frequencies (RF) and electromagnetic fields (EMFs) are non-ionising, and their exposure limits are even 100-fold lower than those emitted from the Sun in the whole RF-EMF spectrum. Nonetheless, this argument has been challenged by numerous experimental and theoretical studies on the diverse biological effects of RF-EMF at much lower power density (W/m2) levels than today’s exposing limits. On the other hand, less attention has been given to counterarguments based on the differences in the physics concepts underlying man-made versus natural electromagnetic radiation (EMR) and on the fact that man’s biology has been adapted to the natural EMR levels reaching Earth’s surface at single EMF wavelengths, which are the natural limits of man’s exposure to EMFs. The article highlights the main points of interaction of natural and man-made radiation with biomatter and reveals the physical theoretical background that explains the effects of man-made microwave radiation on biological matter. Moreover, the article extends its analysis on experimental quantum effects, establishing the “ionising-like” effects of man-made microwave radiation on biological matter. Excerpt The current man-made power density exposure limits are compared to nature’s limits, and some observed biological effects are shown in Figure 3. The biological effects are based on studies presented in the BioInitiative 2012 Report [34,80–139], which have been updated in the present study. Nonetheless, the number of such studies has grown since then, listing as indicative ones that focus on oxidative stress [2,44,53,54,106,128,140,141], DNA damage [54,142] and carcinogenesis [143–147]. Indeed, the lowest power density of 1 × 10−9 W/m2 (1 × 10−6 mW/m2) with observed biological effects (oxidative damage, reactive oxygen species generation, DNA damage/repair failure) is ~10 13-fold higher than a natural exposure limit of ~1 × 10−22 W/m2 (10−19 mW/m2) of exposure to the cosmic frequencies and 10 10- fold lower than the today’s power density exposure limit of 10 W/m2 (1 × 10 4 mW/m2). Even the 3 to 6 × 10−6 W/m2 (3 to 6 × 10−3 mW/m2) limit proposed by the BioInitiative 2012 Report [148] is 10 14− to 10 18−fold higher than the natural exposure limit. Open access paper: mdpi.com

Main findings
This article argues that current RF-EMF exposure-limit rationales based on non-ionizing/thermal assumptions are inconsistent with experimental and theoretical reports of biological effects at much lower power densities than current limits. It emphasizes physical differences between man-made and natural (cosmic/solar) electromagnetic radiation and presents a quantum-mechanical framing suggesting “ionising-like” effects of man-made microwave radiation on biological matter, including free-radical-related cytotoxic changes.
Outcomes measured
