The radiocarbon dating method is based on certain assumptions on the global concentration of carbon 14 at any given time.One assumption is that the global levels of carbon 14 (also called radiocarbon) in the atmosphere has not changed over time.
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.
The other assumption is the corollary of the first; the biosphere has the same overall concentration of radiocarbon as the atmosphere due to equilibrium.
Radiocarbon’s entry into the global carbon cycle starts in the atmosphere where it is formed by the interaction of neutrons produced by cosmic rays with nitrogen atoms.Even after nuclear weapon testing was banned, the bomb effect still remains.According to literature, the excess carbon 14 produced during nuclear weapons testing has already decreased due in part to the global carbon exchange cycle.Although scientists have only known about radiation since the 1890s, they have developed a wide variety of uses for this natural force.Today, to benefit humankind, radiation is used in medicine, academics, and industry, as well as for generating electricity.The level of bomb carbon was about 100% above normal levels between 19.
