There are two techniques in measuring radiocarbon in samples—through radiometric dating and by Accelerator Mass Spectrometry AMS. The two techniques are used primarily in determining carbon 14 content of archaeological artifacts and geological samples. These two radiocarbon dating methods use modern standards such as oxalic acid and other reference materials. Although both radiocarbon dating methods produce high-quality results, they are fundamentally different in principle. Radiometric dating methods detect beta particles from the decay of carbon 14 atoms while accelerator mass spectrometers count the number of carbon 14 atoms present in the sample. Both carbon dating methods have advantages and disadvantages.

How Does Radiocarbon Dating Work? |

Radiocarbon dating also referred to as carbon dating or carbon dating is a method for determining the age of an object containing organic material by using the properties of radiocarbon , a radioactive isotope of carbon. The method was developed in the late s at the University of Chicago by Willard Libby , who received the Nobel Prize in Chemistry for his work in It is based on the fact that radiocarbon 14 C is constantly being created in the atmosphere by the interaction of cosmic rays with atmospheric nitrogen. The resulting 14 C combines with atmospheric oxygen to form radioactive carbon dioxide , which is incorporated into plants by photosynthesis ; animals then acquire 14 C by eating the plants.

radiocarbon dating is used to date

Before Present BP years is a time scale used mainly in archaeology , geology and other scientific disciplines to specify when events occurred in the past. Because the "present" time changes, standard practice is to use 1 January as the commencement date epoch of the age scale, reflecting the origin of practical radiocarbon dating in the s. The abbreviation "BP" has alternatively been interpreted as "Before Physics"; [1] that is, before nuclear weapons testing artificially altered the proportion of the carbon isotopes in the atmosphere, making dating after that time likely to be unreliable.

Radiocarbon dating is a method that provides objective age estimates for carbon-based materials that originated from living organisms. The impact of the radiocarbon dating technique on modern man has made it one of the most significant discoveries of the 20th century. Archaeology and other human sciences use radiocarbon dating to prove or disprove theories.
