has any person tried this - when lightning is around use their
radio to find how many watts of am and fm radio waves are made by
lighning

thank you for any answers

Very little FM, but as the EMF generated by lightning ranges from near
DC to gamma rays, you likely need to be a bit more specific.

Gamma rays...? Really?

I guess I should have read first. They speculate that electrons
traveling at near light speeds encounter nuclei and release their energy
as gamma ray photons. Very interesting. Seems this was discovered
relatively recently (~20 years ago).

Even so, the gamma rays are not a direct part of the radiation of the
lightning bolt, but rather are a result of the large EM field and are
relatively uncommon compared to lightning in general.

"Remarkably, we have found that any thunderstorm can produce gamma rays,
even those that appear to be so weak a meteorologist wouldn't look twice
at them," said Themis Chronis, who led the research at the University of
Alabama in Huntsville (UAH)
