Observing this simple phenomenon had eluded physicists for decades.

    Not only does it exist, but bananas give off a fair bit of antimatter due to their decaying potassium isotopes.

    Allegedly, im not smart enough to verify it

      Would an anti-banana give off normal matter?

          I don’t think it would antimatter

        AFAIK, yes, you might wanna look into β± and β־-decay

        AFAIK, yes.

        There are some very small differences between matter and anti-matter, but I don’t think any of them affect radioactivity.

      Bananas produce antimatter, but just barely. The main radioactive material in bananas is Potassium-40. A banana is about 0.358% potassium in all. About 0.012% of naturally occurring potassium is the radioactive Potassium-40. Only 0.001% of all radioactive decay events in postassium-40 produce an antiparticle (a positron).

      An average banana produces a single positron about every 75 minutes.

          You kid but as a kid when I learned about potatoes and lemon batteries I was like “SCALE THIS UP NOW!”
