radioactive dating is a method of dating rocks and minerals using radioactive isotopes this method is useful for igneous and metamorphic rocks which cannot be dated.
Radiometric dating is used to estimate the age of rocks and other objects based on the fixed decay rate of radioactive isotopes learn about halflife and how it is used in different dating methods such as uraniumlead dating and radiocarbon dating in this video lesson.
Dating methods using radioactive isotopes oliver seely radiocarbon method the age of ancient artifacts which contain carbon can be determined by a method known as radiocarbon dating this method is sometimes called c14 or carbon14 dating carbon14 is formed in the upper atmosphere by the bombardment of nitrogen14 by cosmic rays.
A method for determining the age of an object based on the concentration of a particular radioactive isotope contained within it for inorganic materials such as rocks containing the radioactive isotope rubidium the amount of the isotope in the object is compared to the amount of the isotopes decay products in this case strontium.
In most peoples minds today the radioactive dating of the earths rocks by geologists has supposedly proved that the earth is billions of years old.
Other methods of dating are used for nonliving things 40 k decays with a halflife of 13 180 10 9 years to 40 ar which can be trapped in rocks a potassiumargon method of dating developed in 1966 measures the amount of 40 ar arising from the 40 k decay and is compared to the amount of.
radioactive dating what is radioactive dating any method of determining the age of earth materials or objects of organic origin based on measurement of either short.
