  In order to investigate whether the radical pair mechanism (RPM) can explain
the effects of telecommunication frequency radiation on reactive oxygen species
production, we modelled the effects of oscillating magnetic fields on radical
pair systems. Our analysis indicates that the RPM cannot account for the
biological effects observed under exposure to telecommunication frequencies due
to negligible effects under low-amplitude conditions used in experimental
setups. Observable effects on radical pairs at these frequencies would require
hyperfine coupling constants that are precisely fine-tuned to large values that
far exceed those naturally occurring within biological systems. We conclude
that some other mechanism must be responsible for the effects of
telecommunication frequency fields in biological systems.
