Radiometric dating in archaeology
Radiometric Dating:. These isotopes are the result of a radioactive element which has began to decay, eventually turning back into a stable but different element. Albin When an unstable element such as uranium decays it slowly converts into the stable element lead. The parent uranium atoms convert to daughter lead atoms, this occurs over a fixed interval of time. This decay is very consistent and scientists are able to count and measure it through the use of a mass spectrometer or Geiger counter. We are able to then use this information to provide an age of the element being examined.

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 during which the death of a cadaver occurred.
Absolute dating is the process of determining an age on a specified chronology in archaeology and geology. Some scientists prefer the terms chronometric or calendar dating , as use of the word "absolute" implies an unwarranted certainty of accuracy. In archaeology, absolute dating is usually based on the physical, chemical, and life properties of the materials of artifacts, buildings, or other items that have been modified by humans and by historical associations with materials with known dates coins and written history.
