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

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. Mitch Raemsch

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. |
