Real briefly (and this is my opinion from the research I've done) there is a hazard from high EMF's. But the levels that would cause any sort of damage would either have to be continuous over a period of years and years, or so high you would only see them in a MAJOR industrial setting, or both (i.e. standing next to one of Hoover Dam's generators, eating, sleeping, living, for a period of 5 to ten years).
Lower levels of "high" EMF's can cause certain side effects in people who are sensitive to them. But these are entirely resolved almost immediately after leaving the EMF field. Side effects include:
Skin irritation
Nauseau
Paranoia
Disorientation
General "creepy" feelings
And again, these are almost immediately resolved by leaving that area. These "high" EMF's can be found near areas where lots of computers are in use, areas where copper conduit is in large quantity over a large area, and sometimes in older homes where new wiring is often grounded to the old plumbing. Basically, a large charge moving over a large area.
All in all, there is nothing to be scared about when working with EV's as far as EMF's are concerned.
