a. The exposure values in terms of electric and magnetic field strength are the
values obtained by spatially averaging values over an area equivalent to the
vertical cross section of the human body (projected area).
b. These plane-wave equivalent power density values, although not appropriate for
near-field conditions, are commonly used as a convenient comparison with MPEs
at higher frequencies and are displayed on some instruments in use.
c. The ƒ = frequency in MHz.
d. It should be noted that the current limits given in this table may not adequately
protect against startle reactions and burns caused by transient discharges when
contacting an energized object.
