This 2025 review examines claims of biological effects from weak, nonthermal RF magnetic fields and evaluates whether such effects could be mediated by the radical pair mechanism (RPM). It reports that aligning RPM theory with low-level experimental observations remains difficult and that many experimental findings are limited by reproducibility, statistical robustness, and dosimetry issues. The authors conclude a tangible but incompletely understood link may exist and emphasize the need for more rigorous, standardized, interdisciplinary work.
Standards: Exposure Limits for Brief High Intensity Pulses of Radiofrequency Energy Between 6 and 300 GHz
This standards-focused paper evaluates ICNIRP and IEEE (C95.1-2019) exposure limits for brief, high-intensity pulsed RF-EMF between 6 and 300 GHz, particularly when exposures vary within the 6-minute averaging window. Using numerical and analytical modeling with a one-dimensional thermal tissue model, it reports differences in protection against transient skin heating, with IEEE described as more conservative than ICNIRP. The authors propose an adjustment to pulse fluence limits to improve consistency of protection and note that nonthermal and thermoacoustic effects were not analyzed.
