The half-life of a radioactive material is useful for radioactive dating as it helps to predict the time which a substance has existed based on the number of half-lives the radioactive material has undergone.
What is half-life of radioactive materials?
The half-life of radioactive material is the time taken for half the atoms present in a given quantity of the radioactive element to decay.
The half-life of radioactive elements is constant since the atomic nucleus of a radioactive element decays at a constant rate.
Therefore, the half-life of a radioactive material is useful for radioactive dating as it helps to predict the time which a substance has existed based on the number of half-lives the radioactive material has undergone.
