137Cs radionuclide migration in soil of Georgian resorts after 31 years from Chernobyl accident. / N. Kuchava, P. Imnadze, I. Nikolaishvili, L. Chkhartishvili. / Nano Studies. – 2021–2022. – # 21/22. – pp. 75-82. – geo. There is studied the vertical migration of 137Cs radionuclide in the soil of two Georgian resorts – Ureki and Bakhmaro – located at different height from the Black Sea level after 31 years from the Chernobyl accident. The samples were gathered in 2017, i.e., after a period of it’s half-decay. The great interest to the 137Cs migration problem is caused by its physical-chemical properties. The samples of soil in both places were taken on one and the same day (July 15) in the different depths of soil: 0 (surface), 10, 20, 30 and 40 cm. For the investigated two different types of soil the different characters of vertical migration of 137Cs radionuclide is clearly seen. Fig. 1, Tab. 1, Ref. 16.
