the food chain looks like in detail, one fact applies to everything that was once alive. With this curve we get rid of the fluctuating 14C/12C ratio problem, at least to some extent. The first thing to remember is that plants turn the carbon dioxide or CO2 contained in the air into solid organic stuff like barley (for making beer leaves (for shading beer gardens grass, cauliflower. The second difficulty arises from the extremely low abundance of 14C. If it came exclusively from the charcoal used in the smelting process, you get the age of the tree the charcoal was made from, and that should be close enough. That is generally a good thing for normal people because we would not be here or last very long if we would be hit by that radiation.

Since we have some more methods to date things, and since more and more details become clear, we now have a calibration curve: As the examples show, a radiocarbon age of 20 000 (10 000) years translates into 23 900 (11 400) BP years. How do scientist use Carbon-14 to determine the age of an artifact? Supernova explosions nearby may increase the cosmic radiation intensity for a while or maybe not. This supported the idea that the classical worlds of Greece and Rome were at the centre of all innovations. The field school takes place in Belgium, over 5000 miles away from your native California!
