I guess you are no longer able or willing to discuss antimatter.

This thread is over.

Yes. All over. Positrons can't make it through the atmosphere without
interacting.

If you get cancer, your only hope is that your doctor believes
in antimatter. That is the only way he can prescribe a PET scan.
PET=Positron Emission Tomography
In other words, PET scans use positrongs. Positrons are
antielectrons, by the way.

There is no emission source for positrons. They are mistaken.

I'll respond one more time on this on the off-chance that you are
ignorant (1%), and not just stoopid (99% chance). Do you know why I was
talking about bananas? It's because bananas contain lots of potassium,
and natural potassium contains a small amount of a radioactive isotope
(K-40). K-40 sometimes decays by emitting a positron (and a neutrino)
becoming Ar-40, completely naturally. Google "positron decay" or "beta
plus decay" for details. So, positrons may be as close as the nearest
banana. Actually, potassium is in your body, so you may be spewing
positrons now, no need for bananas.

There are quite a few other isotopes that decay by positron emission,
including whichever one(s) they use for PET machines (I don't know what
they use). I think K-40 is the only natural one, however.

Super-energetic X or gamma rays (more than 1.022 MeV) can also produce
positrons via pair production.

So, are you ignorant or just plain stoopid? Your response to this will
let us know.
