Use of Half-life period

Half-life period or half-life of a radioactive element can be used to estimate the amount of radioactive element left out after a given time. Half-life is constant over the lifetime of an exponentially decaying quantity, and it is a characteristic unit for the exponential decay equation. In general, the percent of radioactive element left out is given by 100/(2^n), where n is the number of half-lives elapsed.
