[RFI] Inverse Square Law and RFI

[Tony]

All:

These might be a silly questions, but given how complex this subject is, 
I thought I'd ask anyway.

1. Does the inverse square-law apply to all devices that emit RFI where 
the RF energy emanating from the device falls off exponentially with 
distance?

2. Is it common for power and other utility cables to carry and radiate 
RFI from a device located in a neighbors home over long distances before 
being attenuated?

In a case like that, I would imagine locating the source of interference 
would be nearly impossible with all that RFI being radiated by utility 
lines.
