Carbon1432the radioactive isotope of carbon used in carbon dating has a halflife of 5730 years32so it decays too fast it can only be used to date fossils younger than about 75000 years potassium40 on the other hand has a half like of 125 billion years and is common in rocks and minerals.

Carbon14 dating can only be used to determine the age of something that was once alive it cant be used to determine the age of a moon rock or a meteorite for nonliving substances scientists use other isotopes such as potassium40.
Radiometric dating or radioactive dating as it is sometimes called is a method used to date rocks and other objects based on the known decay rate of radioactive isotopes.
dating methods using radioactive isotopes oliver seely by the bombardment of nitrogen14 by cosmic rays cosmic rays are protons particles and some heavier ions other particles including neutrons are produced by subsequent collisions there is another often used dating technique for samples considerably older than 60000 years.
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 by the stratigraphic correlation method used for sedimentary rocks.
