“Radiation” has two different meanings – and neither of them applies to power-frequency EMFs.
One use of radiation is to refer to ionising radiation – x-rays, gamma rays, alpha and beta particles, and so on. They are called “ionising” because they have enough energy to break chemical bonds – that is how they do damage to the body. EMFs do not have anything like enough energy to break bonds directly [see footnote] and they are not radiation in this sense.
The other use of radiation is to refer to electromagnetic waves where the electric and magnetic fields are coupled together and propagate through space. EMFs are, of course, part of the same electromagnetic spectrum. But whether you get radiation depends basically on the frequency. At high frequencies – radio waves, TV, microwaves etc – the fields are coupled together and you get radiation. But at lower frequencies, such as power frequencies, you get separate electric fields and magnetic fields, and radiation is normally negligible.
So the simple answer is no, EMFs at power frequencies are not radiation.
For a more scientific discussion of frequencies and radiation, see our tutorial on fields. See also a summary of the differences between power-frequency and radiofrequency EMFs.[footnote] You can, of course, get EMFs to break chemical bonds, even at power frequencies - for example a high enough electric field can create forces on the charged components of a molecule strong enough to break bonds, or an intense enough field could impart enough energy to a molecule to heat it up enough to breal bonds. With ionising radiation, however, it is the quantum energy of the radiation itself that breaks the bond directly. The distinction is that for radiofrequency and power-frequency EMFs, the quantum energy is too small to do this.
