How does the allowable power density for RF safety change if duty cycle changes from 100 percent to 50 percent?

  1. It increases by a factor of 3
  2. It decreases by 50 percent
  3. It increases by a factor of 2Respuesta correcta
  4. There is no adjustment allowed for lower duty cycle

Explicación

The exposure limits are averaged over a fixed period, so a transmitter that is on only half the time delivers half the average exposure for the same output. That allows twice the power density during transmission, a factor of 2 increase in the allowable value.
