Radioactive carbon dating of fossils

Other useful radioisotopes for radioactive dating include Uranium -235 (half-life = 704 million years), Uranium -238 (half-life = 4.5 billion years), Thorium-232 (half-life = 14 billion years) and Rubidium-87 (half-life = 49 billion years).The use of various radioisotopes allows the dating of biological and geological samples with a high degree of accuracy.The object's approximate age can then be figured out using the known rate of decay of the isotope.

Radiocarbon dating can be used on samples of bone, cloth, wood and plant fibers.If one knows how much of this radioactive material was present initially in the object (by determining how much of the material has decayed), and one knows the half-life of the material, one can deduce the age of the object.Scientists use a technique called radiometric dating to estimate the ages of rocks, fossils, and the earth.With our focus on one particular form of radiometric dating—carbon dating—we will see that carbon dating strongly supports a young earth.Note that, contrary to a popular misconception, carbon dating is not used to date rocks at millions of years old.
