Tritium in vegetation at various types of radioactive contamination sites under arid climate conditions.

ABSTRACT: This article presents research findings on tritium (3H) in plants at the Semipalatinsk Test Site (STS), including the perimeter of the 'Degelen' site, the riverside zone of the Shagan River, and a conditionally 'background' area-the southeastern part of the STS (SEP). The 3H content in plants was determined in tritiated free water (TFWT) and organically bound 3H (OBT). Plant samples were measured using an ultra-low-level liquid scintillation spectrometer. Maximum 3H concentrations in plants were detected at the 'Degelen' site (TFWT up to 51 ± 5 kBq/kg, ОBТ up to 15 ± 1 kBq/kg) and Shagan River (TFWT up to 39 ± 4 kBq/kg, ОBТ up to 13 ± 1 kBq/kg). The presence of 3H was recorded not only at underground nuclear sites but also in the conditionally 'background' area (TFWT up to 0.18 ± 0.02 kBq/
