T0C08: Of the following actions can reduce exposure to RF radiation

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

The correct answer is A: Relocate antennas. The correct answer is A: Relocate antennas. An action that can reduce exposure to RF radiation is to relocate antennas. Moving antennas farther from people or to locations with less exposure reduces RF exposure. This is often the simplest solution. For amateur radio operators, antenna placement is a key factor in RF exposure. Understanding this helps ensure compliance and protect people near your station. Relocating antennas is often more practical than other options.

The correct answer is A: Relocate antennas. An action that can reduce exposure to RF radiation is to relocate antennas. Moving antennas farther from people or to locations with less exposure reduces RF exposure. This is often the simplest solution. For amateur radio operators, antenna placement is a key factor in RF exposure. Understanding this helps ensure compliance and protect people near your station. Relocating antennas is often more practical than other options.

Why Other Answers Are Wrong

Option B: Incorrect. Relocating the transmitter doesn't significantly reduce exposure - it's the antenna that radiates RF. Moving the transmitter a few feet doesn't help if the antenna is still close to people. Option C: Incorrect. Increasing duty cycle increases exposure, not reduces it. Higher duty cycle means more transmitting time, which increases average exposure. Option D: Incorrect. Since B and C don't reduce exposure, 'all of the above' cannot be correct. Only relocating antennas reduces exposure.

Exam Tip

Reduce RF exposure = relocate antennas. Think 'R'elocate 'A'ntennas = 'R'educe 'A'ccess (exposure). Moving antennas farther from people reduces exposure. Relocating transmitter doesn't help, increasing duty cycle increases exposure.

Memory Aid

Reduce RF exposure = relocate antennas. Think 'R'elocate 'A'ntennas = 'R'educe 'A'ccess. Moving antennas farther from people reduces exposure. Most effective way to reduce exposure.

Real-World Example

Your antenna is 10 feet from a neighbor's house, causing high RF exposure. You relocate the antenna to the other side of your property, 50 feet from the neighbor. This significantly reduces their exposure because RF field strength decreases with distance. Relocating the antenna is more effective than moving the transmitter or changing duty cycle.
