Yes. We're also getting fairly intense electromagnetic radiation around 12 hours per day. We call it "sunlight", and and the photons are far more energetic than anything coming from power line frequencies. E = hν, and ν for visible light is around 400-800 terahertz, while power line frequencies are 50-60 hertz.
