What must you do if an evaluation of your station shows RF energy radiated from your station exceeds permissible limits?

  1. Take action to prevent human exposure to the excessive RF fields

  2. File an Environmental Impact Statement (EIS-97) with the FCC

  3. Secure written permission from your neighbors to operate above the controlled MPE limits

  4. All of these choices are correct

The correct answer is: Take action to prevent human exposure to the excessive RF fields

If an evaluation of your station indicates that RF energy radiated exceeds permissible limits, the primary responsibility lies in taking immediate action to protect human safety. This means implementing measures to prevent human exposure to the excessive RF fields. The guidelines provided by the FCC emphasize the importance of adhering to Maximum Permissible Exposure (MPE) limits for RF radiation to ensure the safety of individuals in the vicinity of your station. Other options, such as filing an Environmental Impact Statement or securing written permissions, may not be applicable or necessary in all situations regarding RF exposure. They represent different aspects of regulatory compliance or neighbor relations yet are not direct actions aimed at mitigating immediate risks to human exposure. Therefore, the most immediate and critical step is to take action to prevent exposure to harmful RF levels, making that the correct response in this scenario.
