EMC and propagating fields

Enjoy the field of EMC. Measuring propagating fields is easy. Understanding the source of where the field is generated and how this field is propagated ensures job security for many, especially if we are dealing with unintentional radiators. Should we even care about the signal measured by an antenna, especially if it does not cause harm to the environment? Remember, the above quiz has no solution. The answer "it depends" illustrates why EMC engineers have a difficult time trying to achieve compliance when there are many unknown or useless variables present in a problem.
