Radiometric dating , radioactive dating or radioisotope dating is a technique which is 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. Together with stratigraphic principles , radiometric dating methods are used in geochronology to establish the geologic time scale. By allowing the establishment of geological timescales, it provides a significant source of information about the ages of fossils and the deduced rates of evolutionary change. Radiometric dating is also used to date archaeological materials, including ancient artifacts.
Chronological dating - Wikipedia
Since the radioisotope dating techniques, discussed on this web page, do not date the fossil but the rock surrounding the fossil; We need to look at a different set of assumptions than is necessary when considering either C or Amino Acid dates. Evolutionists believe that the fossil will date the same as the surrounding rock because the radioisotope clock is generally thought to reset to zero. However, what would a Creationist need to assume or question when looking at this problem involving the reseting of the clock? When trying to understand Radioisotope Dating techniques from the short time perspective of the Creationary Paradigm, it is important that we understand the assumptions made by both the Scientific Community and the much smaller Creation Science Community.

Everything Worth Knowing About ... Scientific Dating Methods
Dating techniques are procedures used by scientists to determine the age of a specimen. Relative dating methods tell only if one sample is older or younger than another sample; absolute dating methods provide a date in years. The latter have generally been available only since Many absolute dating techniques take advantage of radioactive decay , whereby a radioactive form of an element is converted into another radioactive isotope or non-radioactive product at a regular rate.
Chronological dating , or simply dating , is the process of attributing to an object or event a date in the past, allowing such object or event to be located in a previously established chronology. This usually requires what is commonly known as a "dating method". Several dating methods exist, depending on different criteria and techniques, and some very well known examples of disciplines using such techniques are, for example, history , archaeology , geology , paleontology , astronomy and even forensic science , since in the latter it is sometimes necessary to investigate the moment in the past in which the death of a cadaver occurred.
