E0A02

When evaluating RF exposure levels from your station at a neighbor’s home, what must you do?

  • A.Ensure signals from your station are less than the controlled maximum permissible exposure (MPE) limits
  • B.Ensure signals from your station are less than the uncontrolled maximum permissible exposure (MPE) limits (correct answer)
  • C.Ensure signals from your station are less than the controlled maximum permissible emission (MPE) limits
  • D.Ensure signals from your station are less than the uncontrolled maximum permissible emission (MPE) limits

WhyEvaluating RF exposure at a neighbor's home requires ensuring signals from your station are less than the uncontrolled maximum permissible exposure limits. When evaluating RF exposure at a neighbor's home, a location the amateur doesn't control and where the neighbor hasn't been made aware of or trained on RF safety, the applicable standard is the stricter uncontrolled maximum permissible exposure limit, not the higher controlled limit that applies only to the amateur's own station location where the operator has direct control over exposure, answer B. The controlled limit is the wrong standard for a neighbor's property, and "maximum permissible emission" isn't the correct term at all, the FCC's standard is maximum permissible exposure, not emission.
