Bananas always get the hype for being particularly rich in potassium-40, which is the unstable isotope, but Brazil nuts have far more, and potato and carrot are about as radioactive as banana.

But can you use a potato for scale?

The problem is it also contains a non-insignificant quantity of banana.

Don’t they annihilate each other when they encounter matter? How can a banana contain antimatter safely?

They do, and it can't. It's getting annihilated the first time it touches normal matter, producing other radiation. Nuclear decay in the banana produces more antimatter.

That's a good idea for Star Trek. They allready had the mushroom powered warpdrive. So a starship powered by bananas isn't that far fetched.
