If you’ve ever had bananas, you consumed an active source of radiation. They are rich in potassium, and only a few of them are naturally occurring radioisotopes. 40K (potassium-40). This may sound scary, but levels are safe for human consumption and have fun side effects, neutrinos. Beta decay is one of the ways in which unstable atoms undergo radioactive decay, converting potassium to calcium with the help of basic particles.
