What about electron-positron production?
At any one time there should also be plenty of
positrons around, so you have to count them
also, not?
Just a small quibble.

Electron-positron pairs are ephemeral in nature,
quickly recombining and disappearing as photons.
I suppose you could find a way to put a ballpark
figure to how many electrons are in existence on
average due to this process. Perhaps from a map
of the 0.511MeV line intensity (annihilation
energy of electron-positron pairs).
