Half lives used carbon dating fossils

The half-lives of several radioactive isotopes are known and are used often to figure out the age of newly found fossils.

Different isotopes have different half-lives and sometimes more than one present isotope can be used to get an even more specific age of a fossil.

By measuring the ratio of the amount of the original radioactive element to the daughter isotope, scientists can determine how many half-lives the element has undergone and from there can figure out the absolute age of the sample.Archaeologists use the exponential, radioactive decay of carbon 14 to estimate the death dates of organic material.The stable form of carbon is carbon 12 and the radioactive isotope carbon 14 decays over time into nitrogen 14 and other particles.Carbon-14 is created from nitrogen-14 in the upper atmosphere of the earth.Radiation from the sun collides with atoms in the atmosphere.
