摘要

Tritium behavior in soil–plant systems near a heavy water reactor was investigated by analyzing tissue-free water tritium (TFWT) in plants, tritiated water (HTO) in soil, and organically bound tritium (OBT) in leaves and soil. Available soil water (ASW), defined by volumetric content relative to permanent wilting point, characterized moisture status. Negative values in subsurface clay layers created hydrological barriers that inhibited tritium migration and promoted accumulation. Long-term monitoring shows leaf enrichment factors (EF) and soil OBT to HTO ratios approaching unity, indicating dynamic equilibrium under continuous reactor operation.
