Which of the following is used to determine RF exposure from a transmitted signal?

  1. Its duty cycle
  2. Its frequency
  3. Its power density
  4. All these choices are correctՃիշտ պատասխան

Բացատրություն

Exposure is assessed from the power density in the field, from the frequency, because the permitted limits vary with frequency, and from the duty cycle, because the limits apply to a time-averaged value. All three enter the calculation, so no single one is sufficient.
