Um...
This thread is getting more interesting. 1 millivolt per meter is about
the size of it, at 3 m for the typical test failure.
I suspect at 1 m or closer we will be measuring much more than 1 mV/m is
(1000 microvolts/m or) 60 dBuV/m if the source is a high impedance source
(most probably in the near field unless we are working in the ) but then we
can never know for sure if it is High Z or Low Z.
;-)
Some applied chemist could work hard on the idea of a glowing gas and that
will make our lives very interesting. We will be measuring luminous
intensity! probably with an optical instruments and some form of a camera
in place of an antenna an a EMI receiver for electric field strength. :-)

Please respond to "Ken
Javor"
I hate to be a spoilsport but I believe we are also missing something which
will react at millivolt or milliamp/meter field intensities. All these
other sensors are reacting to relatively strong stimuli.
