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?

Deep Dive: G0A05

The correct answer is A: Take action to prevent human exposure to the excessive RF fields. What you must do if an evaluation of your station shows that the RF energy radiated exceeds permissible limits for possible human absorption is to take action to prevent human exposure to the excessive RF fields. You must reduce exposure by increasing distance, reducing power, using barriers, or other means. For amateur radio operators, this is mandatory. Understanding this helps ensure compliance.

Why Other Answers Are Wrong

Option B: Incorrect. Filing an Environmental Impact Statement isn't required - you must take action to prevent exposure, not file statements. EIS filing isn't the action. Option C: Incorrect. Securing written permission from neighbors isn't sufficient - you must take action to prevent exposure, not get permission. Permission isn't the action. Option D: Incorrect. Since B and C are not correct, 'all of the above' cannot be correct. Only taking action to prevent exposure is required.

Exam Tip

Exceeds RF limits = take action to prevent human exposure. Think 'E'xceeds 'L'imits = 'E'liminate 'L'ikelihood of exposure. You must reduce exposure by increasing distance, reducing power, using barriers, or other means. Not file EIS, not get permission - just take action to prevent exposure.

Memory Aid

Exceeds RF limits = take action to prevent human exposure. Think 'E'xceeds 'L'imits = 'E'liminate exposure. You must reduce exposure by increasing distance, reducing power, using barriers, or other means. Mandatory compliance action.

Real-World Example

Your station evaluation shows RF exposure exceeds limits. You must take action: increase distance to antennas, reduce power, install barriers, restrict access to high-exposure areas, or other measures to prevent human exposure. This is mandatory - you cannot operate with excessive exposure. Taking action to prevent exposure is required.
