Did you know that your arguably favourite fruit is radioactive? YES!
Bananas are rich in potassium, an important mineral needed by the body to function properly. A low potassium diet leads to Hypokalemia which can make muscles feel weak, cramp, twitch, or even become paralyzed, and abnormal heart rhythms may develop. Anyway, bananas are great for this! The Potassium (K) here, and in other foods since is a widely encountered element, has a 0.012% chance of being radioactive. These K-40 atoms spontaneously decay, releasing electrons (beta radiation) as well as gamma rays. HOW FUN.
