Each of the decay product isotopes in the decay chain has its own half-life, and once it is formed it begins its decay to the next isotope in the sequence. The half-life of radon-222 is only 3.8 days. Some isotopes in the 238U decay chain series have half-lives on the order of minutes, and for polonium-214 it is only 164 micro-seconds
