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. WebThe carbon-14 method was developed by the American physicist Willard F. Libby about 1946. It has proved to be a versatile technique of dating fossils and archaeological …
