Taking action to prevent human exposure to excessive RF fields is essential for ensuring safety and compliance with regulations. The emission of radio frequency (RF) energy that exceeds permissible limits can pose health risks to individuals near the transmitting station. It is the operator's responsibility to maintain a safe environment, which includes addressing any situations where RF exposure may be harmful.

Modern regulations, including those set forth by the Federal Communications Commission (FCC) in the United States, require operators to ensure that their station operates within prescribed limits to protect both themselves and the general public. This may involve adjusting the station's power output, implementing physical barriers, or repositioning antennas to keep RF exposure within safe levels.

The other choices may not directly address the immediate need for safety. Upgrading equipment might solve issues in the long term, but it does not resolve the current excessive emissions. Changing operating frequency could also be a stopgap measure, but if excessive RF is still a problem, it may not solve the underlying issue. Ignoring the situation simply because there are no complaints is risky and irresponsible, as potential exposure could still be harmful even if it hasn't yet led to someone reporting it. Safety must always take precedence over convenience or ease.
