Half-life of an element is the time required for half of a given sample of radioactive element to change to another element.The rate of change of concentration is calculated by the formula A(t) = Ao (1/2)tγ where γ is the half-life of the material, Ao is the initial concentration of the radioactive element in the given sample, A(t) is the concentration of the radioactive element in the sample after time t. If Radium has a half-life of 1600 years and the initial concentration of Radium in a sample was 100%, then calculate the percentage of Radium in that sample after 2000 years.
