The mythology of modern dating methods
But new research by creationists has revealed a large number of problems with radiometric dating.
But this method is also useful in many other disciplines.
Historians, for example, know that Shakespeare's play Henry V was not written before 1587 because Shakespeare's primary source for writing his play was the second edition of Raphael Holinshed's Chronicles, not published until 1587.
Thus, 1587 is the post quem dating of Shakespeare's play Henry V.
Radiometric dating is based on the decay rate of these isotopes into stable nonradioactive isotopes.
To date an object, scientists measure the quantity of parent and daughter isotope in a sample, and use the atomic decay rate to determine its possible age.
