What does “time averaging” mean when evaluating RF radiation exposure?

  1. The average amount of power developed by the transmitter over a specific 24-hour period
  2. The average time it takes RF radiation to have any long-term effect on the body
  3. The total time of the exposure
  4. The total RF exposure averaged over a certain periodپاسخ درست

توضیح

The exposure limits are not instantaneous ceilings; they apply to exposure averaged over a defined period, so a short high-power transmission and long periods of receiving average out to a lower figure than the peak. Time averaging means the total exposure spread over that period.
