Aim: To understand the past is instrumental for predicting the future. Therefore, dating of objects – be they from human activities or from nature – is of prime interest in science. Radionuclides are themost useful tool to tackle this problem. Their half-lives may be used as a clock to measure elapsed time. However, a number of conditions have to be met for proper application of such datingmethods. Our environment is rich in radionuclides, mostly of natural origin but partly also from anthropogenic sources such as nuclear weapons testing or from nuclear accidents. This chapter summarizes applications of such radionuclides for dating purpose.
Special emphasis is given to radiocarbon, 14C. Formany applications this radioisotope of carbon is the most important dating radionuclide that enables to cover time horizons from the present until about 60 000 years ago. The use of parent/daughter systems is described as well.
Two other short sections address dating via stored signals in the samples from radioactive transformation. These are fission track and thermoluminescence dating.
