Thus, measuring the ratio of D to L in a sample enables one to estimate how long ago the specimen died. This technique is based on the principle that all objects absorb radiation from the environment.

This method works because some unstable radioactive isotopes of some elements decay at a known rate into daughter products. The relative dating is the technique to ascertain the age of the artifacts, rocks or even sites while comparing one from the other. Relative age dating is a scientific process of evaluation used to determine the relative order of past events, but does not determine the absolute age of an object or date of an event. Relative dating is determined by comparing its placement with that of fossils in other layers of rock.
