Digital BW, The Print

I've been concerned about this possibility ever since I heard of electron 
beam scanning being used.

Flash cards store their information with stored charge, and it seems 
eminently possible that an electron beam could interfere with stored charge, 
along with the same damaging effects as an electromagnetic pulse if the 
intensity is high enough.
