It is fission-track dating that is of special value and promise for archaeological objects in view of its demonstrated success in dating geologically young rocks (a few million years old).

U occurs at a known rate, the age of a mineral or glass can be calculated from the amount of uranium and number of spontaneous fission tracks it contains.

In other words, the change in numbers of atoms follows a geometric scale as illustrated by the graph below.other carbon isotopes in the same ratio as exists in the atmosphere.decay or the rate of other cumulative changes in atoms resulting from radioactivity. The various isotopes of the same element differ in terms of atomic mass but have the same atomic number..One half-life is the amount of time required for of the original atoms in a sample to decay.Although, organic materials as old as 100,000 years potentially can be dated with AMS, dates older than 60,000 years are still rare.Paleoanthropologists and archaeologists must always be aware of possible radiocarbon sample contamination that could result in inaccurate dates.
