Power Line Radiation

[Fallingwaffle]

How do we determine the amount of radiation, EMF, and/or energy emitted from a utility line carry an electric circuit? How do we measure the amount of radiation emitted from the utility line over a time period?

Do you mean in general or to audit for safety or something?

You might want to start in the references to this article. Some look promising.

If you're interested in the 'how' then I believe this is the relevant standard, from 1994 anyway. Limits might have changed but I doubt the measurement technique changed much. You'll probably have to pay to get a more recent one. The document below does assume knowledge in the field.
