Abstract
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.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
