Description
The widespread use of radiofrequency (RF) communication has increased the exposure of organisms to electromagnetic fields, fueling debate about the potential biological effects of weak RF radiation. Experimental studies have suggested that low-amplitude RF fields may influence cellular metabolism, sleep patterns, or even cancer-related processes; however, these claims remain controversial, largely because the underlying physical mechanisms are unclear. A central concept in this discussion is the radical pair mechanism (RPM), a quantum-mechanical framework proposed to mediate magnetic and RF field effects in biology. Although the RPM has been invoked to explain magnetoreception and other magnetic-field-dependent chemical processes, it often struggles to account for observations at weak, non-thermal RF field strengths. In this talk, the applicability of the RPM to weak RF effects will be examined across different biological systems, highlighting both its potential and its limitations.
