Simple definition of radiocarbon dating

The uncalibrated date is given with the unit BP (radiocarbon years before 1950).

The calibrated date is also presented, either in BC or AD or with the unit cal BP (calibrated before present - before 1950).

The highest rate of carbon-14 production takes place at altitudes of 9 to 15 km (30,000 to 50,000 ft).

At high geomagnetic latitudes, the carbon-14 spreads evenly throughout the atmosphere and reacts with oxygen to form carbon dioxide.

This is affected by solar activity and the earth’s magnetic field.

Luckily, we can measure these fluctuations in samples that are dated by other methods.

Radiocarbon dating works by comparing the three different isotopes of carbon.

Isotopes of a particular element have the same number of protons in their nucleus, but different numbers of neutrons.

One of the most frequent uses of radiocarbon dating is to estimate the age of organic remains from archaeological sites.

So, every living thing is constantly exchanging carbon-14 with its environment as long as it lives. The carbon in its body will remain until it decomposes or fossilizes.

The amount of carbon-14 gradually decreases through radioactive beta decay with a half-life of 5,730 years.
