However, rocks and other objects in nature do not give off such obvious clues about how long they have been around.So, we rely on radiometric dating to calculate their ages.Radiometric dating or radioactive dating is a technique used to date materials such as rocks or carbon, in which trace radioactive impurities were selectively incorporated when they were formed.The method compares the abundance of a naturally occurring radioactive isotope within the material to the abundance of its decay products, which form at a known constant rate of decay.As we have mentioned before each radioactive isotope has its own decay pattern.Not only does it decay by giving off energy and matter, but it also decays at a rate that is characteristic to itself.Many Christians have been led to distrust radiometric dating and are completely unaware of the great number of laboratory measurements that have shown these methods to be consistent.Many are also unaware that Biblebelieving Christians are among those actively involved in radiometric dating.


The term halflife is defined as the time it takes for onehalf of the atoms of a radioactive material to disintegrate. Wiens has a Ph D in Physics, with a minor in Geology.His Ph D thesis was on isotope ratios in meteorites, including surface exposure dating.The methods work because radioactive elements are unstable, and they are always trying to move to a more stable state. This process by which an unstable atomic nucleus loses energy by releasing radiation is called radioactive decay.The thing that makes this decay process so valuable for determining the age of an object is that each radioactive isotope decays at its own fixed rate, which is expressed in terms of its halflife.Let's look closely at how the halflife affects an isotope. Therefore, after one halflife, you would have 5 grams of Barium139, and 5 grams of Lanthanum139.
