Carbon Dating - HyperPhysics Concepts Carbon dating is a variety of radioactive dating which is applicable only to matter which was once living and presumed to be in equilibrium with the atmosphere, taking in carbon dioxide from the air for photosynthesis.. Cosmic ray protons blast nuclei in the upper atmosphere, producing neutrons which in turn bombard nitrogen, the major constituent of the atmosphere .

Applying Carbon-14 Dating to Recent Human Remains. Archaeologists have long used carbon-14 dating (also known as radiocarbon dating) to estimate the age of certain objects. 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.

Is Carbon Dating Reliable? | CARM.org Even if the rate of decay is constant, without a knowledge of the exact ratio of C12 to C14 in the initial sample, the dating technique is still subject to question. (4.) Traditional 14C testing assumes equilibrium in the rate of formation and the rate of decay.

Dating a Fossil - Carbon Dating | HowStuffWorks Because the half-life of carbon-14 is 5,700 years, it is only reliable for dating objects up to about 60,000 years old. However, the principle of carbon-14 dating applies to other isotopes as well. Potassium-40 is another radioactive element naturally found in your body and has a half-life of 1.3 billion years.

How Carbon-14 Dating Works | HowStuffWorks 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.
