Plain-language answer: RF exposure is the electromagnetic energy a person can absorb or encounter near transmitting antennas and equipment.
Why the definition matters
Exposure depends on frequency, power, duty cycle, antenna gain and pattern, distance, environment, and whether the area is controlled or accessible to the public.
Use the number correctly
Evaluate the complete installed station under current rules, preserve required separation, restrict access, and reassess after equipment, antenna, power, or location changes.
The common mistake
Using transmitter power alone to decide that an installation is safe.
Measurement and safety boundary
Keep reference units, bandwidth, detector, direction, averaging, and test conditions attached to every number. Current regulator requirements and the complete installed system control RF-exposure compliance.
