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. WebSep 22, 2024 · Radiocarbon dating was discovered when chemist Willard Libby realized radioactive carbon-14 ( 14 C) is made in the Earth’s atmosphere, and then absorbed into plants and entered into the carbon cycle. Since 14 C is radioactive, it decays at a relatively quick exponential rate (Figure 1), while non-radioactive carbon ( 12 C) does not.
