Major dating methods used by archaeologists
Depending on the isotope, this can range from milliseconds to billions of years.
It's development revolutionized archaeology by providing a means of dating deposits independent of artifacts and local stratigraphic sequences.
This produces radiation and is particularly prominent with larger atoms that are easily able to fall apart spontaneously, leading to new elements or a lighter form of the original element.
The time it takes for half of the atoms of an element in a sample to decay is known has its half-life.
Animals eating those plants in turn absorb Carbon-14 as well as the stable isotopes.
This process of ingesting C-14 continues as long as the plant or animal remains alive.
