Once an organism dies, the carbon-14 decays at a known rate, providing a way to calculate the time since death.

To date a sample, scientists measure the amount of carbon-14 remaining and compare it to the initial level when the organism was alive. By knowing the half-life of carbon-14 (about 5,700 years), they can calculate the age of the sample.

However, radiocarbon dating has limitations and factors that can affect its accuracy. Contamination of the sample with modern carbon can distort the results, as can the presence of other isotopes of carbon. Additionally, changes in the Earth's magnetic field and solar radiation can affect the production of carbon-14 in the atmosphere, leading to inaccuracies. To account for these factors, radiocarbon dates are often calibrated using curve-fitting methods to align the measurements with known historical dates.

In conclusion, radiocarbon dating provides a valuable tool for determining the age of organic materials, but it is important to consider its limitations and potential sources of error when interpreting the results.
