EM radiation is defined by it's wavelength and amplitude. Whether it is from a 'natural' source is completely irrelevant in terms of the effect it has. I guess humans have changed the mix of wavelength we are exposed to a bit. E.g. more RF radiation from phones and base stations. But I'm not sure how significant those changes are in the overall 'background EM fields we live in'. |
