Question

Quizplus · Accepted Answer

Radiometric dating techniques are based on the principle of a regular, known rate of isotopic decay. This involves the measurement of the amount of a specific radioactive isotope present in a sample and the calculation of how much time has passed since it underwent radioactive decay, based on the half-life of the isotope.
