Radiometric dating how stuff works

The carbon-14 decays with its half-life of 5,700 years, while the amount of carbon-12 remains constant in the sample.

The use of various radioisotopes allows the dating of biological and geological samples with a high degree of accuracy.

Instead scientist use an accelerator mass spectrometer to measure the ratio of the carbon-14 atoms to the carbon-12 atoms.

A mass spec can do this easily with proper preparation.

Carbon-14 dating is a way of determining the age of certain archeological artifacts of a biological origin up to about 50,000 years old.

It is used in dating things such as bone, cloth, wood and plant fibers that were created in the relatively recent past by human activities.
