It has been argued that cellphones are safe because a single microwave photon does not have enough energy to break a chemical bond. We show that cellphone technology operates in the classical wave limit, not the single photon limit.  Based on energy densities relative to thermal energy, we estimate thresholds at which effects could be possible. These seem to correspond somewhat with many experimental observations.
