And we also know which wavelengths do affect the cells: the wavelengths shorter, not longer, than 200-something nanometers (i.e. < 0.2e-6 m). That is, UV light

And we also know which wavelengths do affect the cells: the wavelengths shorter, not longer, than 200-something nanometers (i.e. < 0.2e-6 m). That is, UV light and all shorter EM, like X-rays (specifically < 0.01e-6 m). That's at least 1e13 times shorter than 5000km of 60 Hz. https://en.wikipedia.org/wiki/Ultraviolet_germicidal_irradiation https://en.wikipedia.org/wiki/Ultraviolet_germicidal_irradia... All the living organisms get a lot of EMF of longer wavelengths: the plain, sub-UV light, for the start. Much closer to the UV (e.g. blue light ~ 0.45e-6 m).
