Could be I suppose. Wouldn't that imply that if your PC is fried by a nuke
due to EMP, you wouldn't be far behind (since if gamma rays cause EMP, your
DNA'd be shredded too by them... right along with your electronics based
friend.)
 
Vs. where if it was the intense burst of -radio- waves that caused EMP, you
might have a chance to biologically survive (at least in the moment) when
your PC is fried by EMP from a nuke.

Might be. Though I wonder if EMP is caused by interaction between oxygen /
nitrogen being bombarded with high-intensity gamma rays? Because that seems
to be what Wik implies here. Intense radio waves seems to me to make more
sense.
