Well, from the reading I've done, the EM field problem is seriously
overrated.  No consistant evidence or mechanisms: it has more to do
with politics than science right now.

And small B&W CRTs are used in camcorder viewfinders: mine will put out 
only twice as much emissons: you don't see anyone trying to ban these
camcorder viewfinders, do you?
