How does radiometric dating determines age

WebFeb 24, 2012 · Radiometric Dating of Rocks. Radiometric dating is the process of using the concentrations of radioactive substances and daughter products to estimate the age of a material. Different isotopes are used to date materials of different ages. Using more than one isotope helps scientists to check the accuracy of the ages that they calculate. WebNov 29, 2024 · Radiometric dating is self-checking, because the data (after certain preliminary calculations are made) are fitted to a straight line (an “isochron”) by means of standard linear regression methods of statistics. The slope of the line determines the date, and the closeness of fit is a measure of the statistical reliability of the resulting date.
