How do scientists use this dating technique to determine the ages of rocks or fossils? they measure the rate of the decay of radioactive. fossils of known ages. Absolute dating is used to determine a precise age of a fossil by using radiometric dating to measure the decay of isotopes, either within the fossil or more often the rocks associated with it. Scientists can use certain types of fossils referred to as index fossils to assist in relative dating via correlation.
