All a matter of proper EM shielding... Run the detector and pc (or amplfied
speaker.. if you hear lots of clicks,you're getting radiated) inside a
shielding cage of chicken wire or something.  Xrays will go right through
the screening.  The Aware Electronics unit has a peak sensitivity to 60 keV
xrays apparently, and I don't know how fast it falls off. It would be hard
to tell what the energy of the xrays is coming off a lightbulb in the TC
field (it probably ISNT 1 MeV, but a lot less)
