Final answer:

Half-life is the time required for half of a radioactive material to decay, providing a measure of decay rates in radioactive samples.


Explanation:

Half-life is the time required for half of a radioactive material to decay. It is a measure of how long it takes for the number of radioactive nuclei in a given sample to decrease to half of the initial quantity.

For example, if the half-life of a radioactive element is 5 years, after 5 years, half of the radioactive nuclei in the sample would have decayed.

Each subsequent half-life interval removes another half of what remains, making it a crucial concept in understanding radioactive decay rates.
