That is why carbon-14 is a radioactive isotope-it contains a combination of protons and neutrons in its nucleus that is not stable enough to hold together indefinitely.Unlike other body cells, neurons don’t undergo mitosis (cell splitting).This marker (bromodeoxyuridine) attaches onto the DNA of splitting cells, like neuroblasts.See how random decay times relate to the half life.(Previously part of the Nuclear Physics simulation - now there are separate Alpha Decay and Nuclear Fission sims.) Learn about different types of radiometric dating, such as carbon dating.
