Carbon dating objects
Radiocarbon dating is a method of estimating the age of organic material.
It was developed right after World War II by Willard F.
Green plants absorb the carbon dioxide, so the population of carbon-14 molecules is continually replenished until the plant dies.To measure the amount of radiocarbon left in a artifact, scientists burn a small piece to convert it into carbon dioxide gas.Radiation counters are used to detect the electrons given off by decaying Carbon-14 as it turns into nitrogen.Love-hungry teenagers and archaeologists agree: dating is hard.But while the difficulties of single life may be intractable, the challenge of determining the age of prehistoric artifacts and fossils is greatly aided by measuring certain radioactive isotopes.

For example, in 1991, two hikers discovered a mummified man, preserved for centuries in the ice on an alpine mountain.
