sure your monitor might radiate X-Rays (I imagine not very many nor at any
high power otherwise they would be banned for health reasons) but the real
question is can that radiation be used to reconstruct what you are doing?
apart from some intelligence that you've got the computer ON that is.

Also previsously someone also mentioned TEMPEST scanning from satelittes, I
would be very dubious about that, some simple radio physics tells you that
the power the satellite picks up would be miniscule, and (more to the
point) obliterated by background noise and interference with the other many
thousands of monitors and other electrical/radio equipment in your area. I
think its more a "building next door" type scenario. Not even the NSA can
change the laws of physics.
