Radiocarbon scientists used this knowledge to test their theories regarding the mixing rates of carbon 14 through various carbon reservoirs.They found out that tree rings do not exchange radiocarbon with other tree rings.Nowadays, radiocarbon scientists had to perform calibration not only to convert their radiocarbon year results into calendar year but also to take into account the various factors that have major effects on the global levels of carbon 14, one of which is nuclear weapons testing.There are two human activities recognized to have irreparably changed the global radiocarbon levels—the burning of fossil fuel and nuclear weapons testing.By the 1990s, the carbon 14 level was only about 20% higher than the theoretical 1950 level as measured by the activity of the oxalic acid reference standard.Bomb carbon is essentially an artificial injection of carbon 14.

According to literature, the excess carbon 14 produced during nuclear weapons testing has already decreased due in part to the global carbon exchange cycle.The carbon 14 produced reacts with oxygen atoms in the atmosphere to form carbon dioxide.This carbon dioxide is no different from those produced by carbon 12 and carbon 13; hence, carbon dioxide with carbon 14 has the same fate as those produced with the other carbon isotopes.The Geochemical Ocean Section Study analyzed ocean water samples from the Atlantic, Pacific, Indian, and Mediterranean Oceans and mapped the presence of bomb carbon.

Results of the study have enabled modelers to analyze the pathway of radiocarbon and its exchange and residence times.Tracer-Free AMS Dating Lab Beta Analytic does not accept pharmaceutical samples with "tracer Carbon-14" or any other material containing artificial Carbon-14 to eliminate the risk of cross-contamination.
