WebMay 3, 2016 · Explanation: At a simple level, carbon-14 dating might be based on an assumption that the rate of production of carbon-14 (due to cosmic rays hitting the upper atmosphere) has been fairly constant. It does vary to some extent. Some of the variation in recent centuries has been caused by burning fossil fuels and by above ground nuclear tests. WebIt will depend on the kind of sample as well as the age of the sample. Something to consider is that there is a "calibration curve" because the amount of carbon 14 in the atmosphere has not been constant over time. This calibration isn't of the same precision at every date so the accuracy of dating will vary depending on how old the sample is.

WebMar 16, 2024 · Step 1. High-energy cosmic rays, in the form of neutrons, strike nitrogen atoms in the upper atmosphere and convert them to the radioactive isotope of carbon, which is carbon-14 (also known as radiocarbon). This quickly oxidises to create mildly radioactive carbon dioxide. About 1.1 per cent of the carbon atoms on Earth are carbon-14. WebApr 8, 2024 · Carbon Dating: Determining the Rate of Radiocarbon Decay After radiocarbon forms, the nuclei of the carbon-14 atoms are unstable, so over time they progressively decay back to nuclei of stable nitrogen-14. 3 A neutron breaks down to a proton and an electron, and the electron is ejected. This process is called beta decay.
