Problems with radiogenic dating

Radioactive dating is a method of dating rocks and minerals using radioactive isotopes.

For geological purposes, this is taken as one year. The belief that radiodating methods give absolute measurements of time is widespread as a result of scientific popularization in journals, conferences, and the media.In fact, due to the difficulties in applying the experimental method to events in the past, all chronometers based on natural or artificial nuclear disintegration need a calibration.This calibration supposes a great number of basic assumptions concerning initial conditions.The choice of these initial conditions affects the results.
