Re: How much x/soft gamma rays does lightning emit?

A lightning flash is composed of a series of strokes with an average of 
about four. The length and duration of each lightning stroke vary, but 
typically average about 30 microseconds. (The average peak power per stroke 
is about 10e12 watts.) Lightning discharges contain the whole spectrum of 
frequencies, below and above what the human eye can perceive. It is known 
that lighting emits xrays and gamma rays but no one has measured or 
quantified the amounts of radiation. It is interesting to note that high 
above thunderclouds the radiation effects can be detected and observed. I 
collected a few websites where you might obtain additional information. The 
Jovian, or Jupiter-like, planets are very large compared to the terrestrial 
planets and are much farther from the sun. They are also called the outer 
planets. These planets are composed mostly of hydrogen and helium in 
gaseous and liquid form. Our space probes have detected intense storms with 
the probable duration of many centuries in Jupiter, but again the strength 
of the electromagnetic emissions has not been quantified. Several 
universities and NASA are in the process of collecting and analyzing these 
data. Sorry I could not be more specific.
