All radioactive isotopes do what over time?

Explanation:
Radioactive isotopes are unstable and transform into more stable nuclei by emitting particles. Over time, these decays occur, so the original isotope gradually converts to other elements and its activity decreases. This happens at a rate described by the half-life, meaning after a certain time, half the original nuclei have decayed. So they decay over time, rather than increase in energy, staying constant, or multiplying.
