Isotopes are important to geologists because each radioactive element decays at a constant rate, which is unique to that element.
This is different to relative dating, which only puts geological events in time Most absolute dates for rocks are obtained with radiometric methods.
The graph expresses the annual evolution of the frequency of use of the word «radioactive dating» during the past 500 years.
Its implementation is based on analysing how often the term «radioactive dating» appears in digitalised printed sources in English between the year 1500 and the present day. * ortunately, geologists have discovered dating methods using radioactivity that permit them to date rocks even billions of years old with a fair degree of accuracy.
