Can carbon dating be used on stone
In recent years, forensic scientists have started to apply carbon-14 dating to cases in which law enforcement agencies hope to find out the age of a skeleton or other unidentified human remains.
The new method is based on the fact that over the past 60 years, environmental levels of radiocarbon have been significantly perturbed by mid-20th-century episodes of above-ground nuclear weapons testing.
Or does stone have its own ways of finding age of carving that is independent of nearby organic material?
First of all, carbon dating is a highly inexact science to begin with.
The problem with this approach: Suppose a museum in the present day has several stone monuments from varying dates.
And they're cleaned and maintained quite well by the curator; there is no organic material on them.
Since then they have been dropping back toward natural levels.
Over the past six decades, the amount of radiocarbon in people or their remains depends heavily on when they were born or, more precisely, when their tissues were formed.
For example, moisture and temperature fluctuation will have a big effect on how a stone weathers.Traditional radiocarbon dating is applied to organic remains between 500 and 50,000 years old and exploits the fact that trace amounts of radioactive carbon are found in the natural environment.Now, new applications for the technique are emerging in forensics, thanks to research funded by NIJ and other organizations.Before the nuclear age, the amount of radiocarbon in the environment varied little in the span of a century.
