Which of the following actions can reduce exposure to RF radiation?

The intensity of RF radiation drops off rapidly as you increase your distance from the radiating source. Therefore, moving your antennas higher up or further away from human-occupied areas is one of the most practical and effective ways to reduce RF exposure. Relocating the transmitter itself does not reduce exposure, because the transmitter box is not what primarily radiates the RF energy—the antenna is. Additionally, increasing the duty cycle means the transmitter is actively transmitting for a larger percentage of the time. This would actually increase your average RF exposure, not reduce it.
