Amateur Radio is basically a safe activity. In recent years, however, there has been considerable discussion and concern about the possible hazards of electromagnetic radiation, including both RF energy and power-frequency (50-60 Hz) electromagnetic fields.  To allay such concerns, the FCC set limits on the amount of RF energy people can be exposed to. Some stations need to be evaluated to see if they are in compliance with the rules.
