Abstract

---

In nuclear explosions in the atmosphere neutrons react with air nitrogen forming radiocarbon. As a result, by October 1963 when the international treaty banning nuclear tests in the atmosphere came into force the content of radiocarbon in the atmosphere exceeded its level of 1950 more than twice. However, then measurements of its concentration showed an exponentially fast decrease. In the atmosphere radiocarbon is present in the form of 14CO2. Its absorption by water, as well as all chemical reactions of radiocarbon and stable carbon isotopes are identical. A joint study of regular trends in concentrations of 14C and CO2 as well as their seasonal variations provides unique information on gas exchange between the atmosphere and the ocean. These results could be treated as a proof for anthropogenic influence on recent history of atmospheric carbon dioxide. Keywords: radiocarbon; carbon dioxide; gas exchange; seasonal variations.
