What is the purpose of absolute dating

Different methods of radiometric dating can be used to estimate the age of a variety of natural and even man-made materials.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.There are different methods of radiometric dating that will vary due to the type of material that is being dated.For example, uranium-lead dating can be used to find the age of a uranium-containing mineral.So, you might say that the 'full-life' of a radioactive isotope ends when it has given off all of its radiation and reaches a point of being non-radioactive.

Even the humblest items of equipment come at a price: laboratories that carry out U-Pb dating wash the bottles they use for two years continuously to eliminate contamination.

In this case, the use of fossils will be absolutely the best method available.
