*Question G0A05:
[97.13(c)(2), 1.1307(b)] What must you do if an evaluation of your station shows that the RF energy radiated by your station exceeds permissible limits for possible human absorption?*  

*Correct Answer is  A: Take action to prevent human exposure to the excessive RF fields*  

### AI Response: (may contain errors)  

When evaluating your amateur radio station, if you find that the RF energy radiated exceeds the permissible limits for human absorption, you must take steps to ensure safety. Here's why the correct answer is A:

1. **Correct Answer: A - Take action to prevent human exposure to the excessive RF fields**
   - The FCC requires that if your station's RF emissions exceed the Maximum Permissible Exposure (MPE) limits, you must take corrective actions to reduce exposure. This could involve reducing power, repositioning antennas, or implementing barriers to prevent access to areas with high RF levels.

2. **Why the other choices are incorrect:**
   - **B: File an Environmental Impact Statement (EIS-97) with the FCC**
     - This is not required for amateur radio stations. An EIS is typically associated with large-scale projects that might significantly affect the environment, not individual radio stations.
   - **C: Secure written permission from your neighbors to operate above the controlled MPE limits**
     - Obtaining permission from neighbors does not exempt you from complying with FCC regulations regarding RF exposure. The responsibility to ensure safety lies with the station operator.
   - **D: All these choices are correct**
     - Since B and C are incorrect, D cannot be correct.

3. **Useful Information:**
   - The Maximum Permissible Exposure (MPE) limits are set by the FCC to protect humans from excessive RF exposure. These limits vary based on frequency, power, and exposure time.
   - A common rule of thumb is to ensure that no one can access areas where RF exposure exceeds the MPE limits, especially in uncontrolled environments like residential areas.

By understanding these requirements, you can ensure your station operates safely and in compliance with FCC regulations.
