Bob,
My recent work indicates that the person can defintely acquire a DC
charge. (actually it is the air dielectric about the rather conductive
person that is charged.) In addition there are also RF concerns. Metal
objects in high RF fields actually act as antennae and can cause RF burns
which appear as painful short spark nips or pinches as oppossed to the
classic DC electrostatic electrical shock. It depends on what you feel
as to what is the real causitive agent involved. The DC charge lingers
after firing. The RF goes away.
