RF Exposure from Small Transmitting Loops
However, the obvious comment is that the small physical size of a loop is
likely to lead to use in a situation (for example, indoors and close to the
operating point) that would/could lead to excessive levels of RF exposure.
For an electrically small loop (the typical loaded loop less than 0.1
wavelength), then it is probably fair to assume that all of the input power
is radiated through the sphere surrounding the loop provided that the
separation is reasonably large,
separation being large - many loop diameters
i.e. in the radiating far field.
