*Question T0C08:
Which of the following actions can reduce exposure to RF radiation?*  

*Correct Answer is  A: Relocate antennas*  

### AI Response: (may contain errors)  

To reduce exposure to RF radiation, the correct action is to **relocate antennas**. Here's why:

1. **Correct Answer: Relocate antennas**
   - Moving antennas further away from areas where people are present decreases the RF radiation exposure. The intensity of RF radiation decreases with distance from the source, following the inverse square law. This means that if you double the distance from the antenna, the exposure is reduced to one-fourth.

2. **Incorrect Choices:**
   - **Relocate the transmitter (Choice B)**: While moving the transmitter can also reduce exposure, it does not necessarily guarantee a reduction in RF radiation exposure for individuals nearby, especially if the antenna remains in the same location. The transmitter's power and the antenna's placement are critical factors.
   - **Increase the duty cycle (Choice C)**: Increasing the duty cycle means the transmitter is on for a longer period, which actually increases RF exposure rather than reducing it. A higher duty cycle results in more continuous RF energy being emitted.
   - **All these choices are correct (Choice D)**: Since increasing the duty cycle is incorrect, this choice cannot be correct.

3. **Useful Rule of Thumb:**
   - The intensity of RF radiation decreases with the square of the distance from the source. This can be expressed as:
   $$ I \propto \frac{1}{d^2} $$
   where:
   - $I$ = intensity of RF radiation
   - $d$ = distance from the antenna

By relocating antennas to a greater distance from populated areas, you effectively reduce the RF exposure to individuals.
