In this paper, we analyze the background activity of anthropogenic radionuclides ( 14 C, 3 H, 137 Cs, and 239,240 Pu), emphasizing 14 C content, in terrestrial and aquatic ecosystems in the Lithuanian border region before the commissioning of a new nuclear power plant in Belarus (BelNPP). In terrestrial samples, the 14 C concentration varied insignificantly—from 98.6 ± 0.7 to 102.2 ± 0.8 pMC, which is close to the 14 C level in atmospheric CO 2 . In aquatic samples, the 14 C concentration varied within wide limits from 76.9 ± 0.7 to 99.6 ± 0.6 pMC, depending on the ecological group of macrophytes. Various ecological groups of macrophytes have experienced the influence of a freshwater reservoir effect. This lowest 14 C content in submerged macrophyte species, within the limits of uncertainty, was very close to the specific activity of 14 C in DIC (78.6 ± 0.6 pMC) in the water of the Neris River. The background 14 C values, together with the data on 3 H, 137 Cs and 239,240 Pu obtained in this study, can be used in the future to assess the contribution of the BelNPP conventional radioactive effluents to the levels of 14 C and other radionuclides in terrestrial and aquatic ecosystems of the transboundary region of Belarus and Lithuania
