[ RadSafe ] " X-rays from lightning photographed "

[Brennan, Mike (DOH)]

I wonder if anyone has looked at outdoor radon (and decay products) in
connection with lightening.  The slight ionization of air due to decay
of these airborne isotopes might provide preferred pathways for the
discharge of the electrical charges.  

Just a thought.

The Florida Chapter HPS had a presentation from someone that works in
the lightning test facility at KSC...

Although he may have erroneous used the term 'gamma' radiation (during
the presentation) , 
there is quite a bit of evidence that a lightning bolt generates some
form of
very hi energy (i.e., 8 to 10 MeV) photon radiation.

X-rays from lightning photographed

Using a custom-built camera the size of a refrigerator, Florida
researchers
have made the world's first crude pictures of X-rays streaming from a
stroke
of lightning.
