What is "while a certain isotope decays?

When a certain isotope decays, it undergoes a process of change in which it transforms into a different element or isotope. This decay process is random and unpredictable, occurring at a specific rate known as the half-life of the isotope.

During the decay of an isotope, it emits radiation in the form of alpha, beta, or gamma particles. This radiation can be harmful to living organisms and must be carefully monitored and controlled in certain situations, such as in nuclear power plants or medical settings.

The decay of isotopes is used in various scientific applications, such as radiometric dating to determine the age of rocks and fossils, and in medical imaging techniques like PET scans. Understanding the decay of isotopes is crucial for advancing our knowledge of the fundamental processes of nature and the universe.
