Seeing as Orion relies on air bursts of nuclear devices to propel it, even 
with the cleanest bombs conceivable, there will still be some fallout and 
of course, radiation in the local area of the launch. Whoever is downwind 
will get dosed - maybe less than what they used to get from the above 
ground tests in Nevada, but dosed nonetheless. This alone will probably 
prevent an Orion style launch from ground to orbit, except in a dire emergency.
If the craft could be launched from orbit, less and smaller devices could 
be used to escape Earth orbit, since most of the work is from the surface 
to LEO. Fallout in space could cause problems for satellites and manned 
stations unless the trajectory was planned carefully to avoid these areas.
