In this paper we describe the first measurements of 210Pb concentrations in sediments, performed in the Institute of Physics, Silesian University of Technology, Gliwice. The reliability of our method has been tested by the 210Pb measurements in the sediments of Lake Gościąż. The reasons for the non-monotonic profile of 210Pb in these sediments have been discussed. We also report and discuss the 210Pb measurements in the sediments formed in front of the Skeidarar glacier (Iceland).
