Tritium ( 3 H) remains a prominent radionuclide detected in notable quantities in all environmental compartments of the Semipalatinsk Test Site (STS). This study presents data describing the levels of 3 H travel in areas of the impact zones of radioactively contaminated STS locations — the Degelen site. Water, soil, sediments, air, and fluorite ore (Karadzhanly deposit product) 3 H activity concentrations (including the speciation) were measured using liquid scintillation with spectrometric equipment “TRI-CARB 2900 TR” (PerkinElmer, USA). Plant samples were measured using “QUANTULUS 1220” (PerkinElmer, USA). Plant samples were measured using “QUANTULUS 1220” (PerkinElmer, USA). The high values were set in free water 3 H in plants (TFWT) – up to 41 kBq/kg, in soils and bottom sediments (TSAW) – 29 and 26 kBq/kg, respectively. The main source of 3 H entering the environmental components is groundwater – up to 78 kBq/kg. Annual effective internal dose from 3 H to personnel during operations at the Karadzhally fluorite deposit does not exceed Standards.
