What factors affect the RF exposure of people near an amateur station antenna?
Frequency and power level of the RF field
Distance from the antenna to a person
Radiation pattern of the antenna
All these choices are correct✓الإجابة الصحيحة
الشرح
Exposure depends on how much power density actually reaches a person, which is set by the transmitter power and frequency, how far away the person is, and where they stand in relation to the antenna's radiation pattern. All three matter, so the all-of-these answer is correct.
