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. WebMay 6, 2024 · Radiocarbon dating is a technique that estimates the exact age of organic materials based on the amount of C14 isotope present in the sample. An isotope is an atom with an abnormal number of neutrons in its nucleus. In the case of C14, it has two additional neutrons compared to the standard carbon 12 atom.
