Knowing about half-lives is important because it enables you to determine when a sample of radioactive material is safe to handle.

For example, you can’t find the remaining amount of an isotope as 7.5 half-lives by finding the midpoint between 7 and 8 half-lives.

This decay is an example of an exponential decay, shown in the figure below.

Finally, after a series of radioactive isotopes are formed it becomes lead-206, which is stable.

Scientists look at half-life decay rates of radioactive isotopes to estimate when a particular atom might decay.

It takes a certain amount of time for half the atoms in a sample to decay.
