“When an organism dies, its radiocarbon clock starts ticking down with a half-life of 5,730 years (meaning it takes that long for half of the radioactive carbon in the organism to decay). If you are starting to feel an inner glow, don’t worry – only one in a trillion carbon atoms is radioactive, so you’re safe.”
