When evaluating a site with multiple transmitters operating at the same time, the operators and licensees of which transmitters are responsible for mitigating over-exposure situations?
Each transmitter that produces 20 percent or more of its MPE limit in areas where the total MPE limit is exceeded
Each transmitter operating with a duty cycle greater than 25 percent
Each transmitter that produces 5 percent or more of its MPE limit in areas where the total MPE limit is exceeded✓Respuesta correcta
Each transmitter operating with a duty cycle greater than 50 percent
Explicación
Where several fixed transmitters together drive an accessible area over the limit, responsibility for correcting it is shared by every licensee whose own emissions exceed 5 percent of the applicable limit at that spot, and duty cycle does not decide responsibility — it only enters the time averaging of a station's own exposure figure. Note a boundary difference in wording: the official pool answer reads 5 percent or more, while the rule reads exceed 5 percent, so a contribution of exactly 5.000 percent falls inside the pool's phrasing but outside the threshold in the regulation.
