سؤال 589

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

  1. Ensure signals from your station are less than the controlled maximum permissible exposure (MPE) limits
  2. Ensure signals from your station are less than the uncontrolled maximum permissible exposure (MPE) limitsپاسخ درست
  3. Ensure signals from your station are less than the controlled maximum permissible emission (MPE) limits
  4. Ensure signals from your station are less than the uncontrolled maximum permissible emission (MPE) limits

توضیح

A neighbour is not a member of the licensee's household, has had no training about the station and cannot control the exposure, so the general population/uncontrolled limits apply rather than the occupational/controlled ones. MPE also stands for maximum permissible exposure, not maximum permissible emission, which disposes of the two remaining choices.
