Sedimentary conditions based on the vertical distribution of radionuclides in small dystrophic lakes: a case study of Toporowe Stawy Lakes (Tatra Mountains, Poland).

ABSTRACT: The aim of this work was to prove the use of radionuclides deposited in sediment core taken from an overgrowing dystrophic lakes surrounded by marsh-peat vegetation to estimate sedimentary conditions. Sediment core samples were taken from the Toporowe Stawy Lakes (Niżni (TSN) and Wyżni (TSW); Tatra Mountains). The sampling was done using a Limnos corer. After the physical sample preparations, gamma measurements were performed. Radiochemical analysis was applied with the aim of determining ²¹⁰Pb radioactivity by means of ²¹⁰Po. The mean values for TSN lake are as follows: ¹³⁷Cs ~ 123 Bq∙kg^-1, ⁴⁰ K ~ 389 Bq∙kg^-1, ²²⁸Th ~ 55 Bq∙kg^-1, ²²⁶Ra ~ 86 Bq∙kg^-1, ²⁴¹Am ~ 5 Bq∙kg
