[ RadSafe ] RE: Thundercloud gamm rays

[Geo>K0FF]

External  Bremsstrahlung occur outside the originating atom ( in another 
atom).
Internal Bremsstrahlung occur inside the atom but external to the nucleus. 
It is the result of inelastic collisions of the electron with the field near 
the nucleus (page 600).


X-Rays come from the electron shell area, while Gamma rays come from inside 
the nucleus.

Besides the location in which they are created, Gamma Rays and X-Rays are 
indistinguishable at a distance. They are of course the same thing.

I see nothing on page 617 that contradicts that.
