放射性元素测定方法

现今在这些学科里，通常采用的是放射性元素测定方法（radiometric dating）。例如，化石中的铀经一系列衰变（请注意：其衰变的速率并非恒定）而成为铅，由此鉴定化石或地球的年龄。

abstract: Radiometric dating (often called radioactive dating) is a technique used to date materials such as rocks, usually based on a comparison between the observed abundance of a naturally occurring radioactive isotope and its decay products, using known decay rates. The use of radiometric dating was first published in 1907 by Bertram Boltwood and is now the principal source of information about the absolute age of rocks and other geological features, including the age of the Earth itself, and can be used to date a wide range of natural and man-made materials.
