Having seen several transactions regarding the development of
space-based X-ray lasers, I've got a few questions of the group.

The description of the device mentions that the driver is a megaton-size
nuclear device.  Is the altitude at which the device is deployed
sufficient to obviate EMP effects?

How transparent is the atmosphere at X-ray wavelengths?  Could the
device be used against ground targets?  What about aircraft at altitudes
of, say, 10,000 meters?
