Radiometric dating is a means of determining the "age" of a mineral specimen by determining the relative amounts present of certain radioactive elements.By "age" we mean the elapsed time from when the mineral specimen was formed.As the activity of a sample is proportional to the number of radioactive nuclides present it is also possible to say that the half-life is the time taken for half of the radioactive nuclides in a sample to decay.
