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.

NEC Article 527, Temporary Installations, requires removal of temporary wiring upon

completion of the experiment for which it was installed.

An overly strict interpretation can obstruct the scientific objectives of the R&D configuration,

but if a liberal interpretation is allowed, there is a possibility that unsafe wiring methods will be

used. The AHJ must consider programmatic needs without sacrificing personnel safety.
