I'm glad we have some knowledgeable people in this area here.

Dave and Bill and others who might know too, speaking of flux, I notice that when I place the probe just next to an active speaker (such as on a phone handset), the reading is quite low. However, when I move the probe, sideways or away from it, the reading spikes. What is it measuring then?

Actually, even if I were to move the probe in the air is a very radiation-free zone, the reading goes up too. I have to wave it very, very vigorously though. :-)
