Bananas Emit Antimatter Almost Every 75 Minutes

Potassium-40 is a fairly unstable isotope, although the half life is nearly a billion years.

Because bananas have so much of this isotope, there is enough decay to generate one positron (approximately) every 75 minutes.

A positron is basically the opposite of an electron. It has the same mass as an electron, but a positive charge instead of a negative one. It is the electron’s antimatter doppelgänger.

    I started stuffing myself with bananas after reading this hoping to turn into POSITRON MAN. I’m not sure if it worked or not. I haven’t been able to leave the bathroom long enough to find out……

    What matter is it anti to? I understand that every matter in the universe has it’s own antimatter and if they meet they will annihilate each other.
