OP is making a distinction between "EM Radiation" (i.e. "light") and "Quasistatic fields".
This is warranted because they are pretty different - light has a frequency distribution, diffracts, etc, and can be focused to propagate energy over distances large compared to its source, whereas quasistatic fields (by definition) have no frequency distribution, and die as 1/r^2 or faster
