The turnover of 14C carbon in forest of the Chernobyl exclusion zone. The Ecological Effects of the Chernobyl Disaster. 8 August 2005. Montreal.

Radioactive isotope 14C is widely used as indicator in the study of carbon turnover. In this presentation we show part of the results which were received while working on the CRDF project - “Distribution of Carbon Isotopes in Forest Ecosystems within the Chernobyl Exclusion Zone”.

The base regional scale of radiocarbon content in tree rings of 1981-2004 years was created for “clean” pine forest zone.

For 50- years old pins from “Clean” Zone and from Chernobyl Exclusion Zone were determined the radiocarbon content in tree rings (1981-2004), in pines, and in roots.

14C content in carbon of various elements of the subsystem: atmosphere-grass-liter –soil, determined for both research sites on the base vacuum thermo-destruction technology has shown noticeable presents of the graphite component of the accidental release.
