Plutonium-239 is a byproduct of the fission reaction used to produce energy in nuclear power reactors. It has a half-life of 24,400 years. A student determines that it will take 97,600 years for the radioactivity of a Pu-239 sample to drop to one-eighth of its original level. Show calculations to support or refute her conclusions.
