This study uses quantum spin-dynamics simulations to evaluate whether radiofrequency (RF) fields can perturb biological radical-pair chemistry (FMNH·/O₂⁻·). The model demonstrates that 2.4 GHz WiFi fields cannot influence singlet yields due to severe amplitude, frequency, and coupling barriers. Conversely, AM broadcasting carriers (530–1700 kHz) resonate with the electron Larmor frequency in the geomagnetic field. The simulations show that AM fields can induce >1% changes in singlet yield, but this effect is restricted to distances under 20 meters from high-power transmitters and requires radical-pair lifetimes exceeding 1 μs. Additionally, multi-frequency AM exposure produces destructive quantum interference, significantly reducing the net effect compared to single-station resonance.
