- Yes. It generates pions, which decay to muons, which decay to electrons
- and positrons. Roughly speaking. If you assume that all the electrons
- and positrons find each other, you end up with gamma rays and neutrinos
- in the end... but the pions and muons last long enough to be exploited.

- There *would* be a lot of gamma rays flying around, to be sure.
