Homer says that we can safely use nuclear power because all radioactive nuclei are gone after two half-lives. Marge says that only the decay rate is zero after two half-lives. Which one, if either, is correct, and why?

◦
Homer, because half of the nuclei disintegrate in each half-life.

◦
Marge, because the number of decays per unit time is halved in each half-life.

◦
Homer, because it's safe to handle radioactive substances after two half-lives.

◦
Both, because when all nuclei disintegrate the decay rate is also zero.

◦
Neither, because one quarter of the nuclei are left after two half-lives.
