Abstract The article presents the results of studying specific organomineral formations—cryoconite sediments—samples of which were taken on the surface of the Witte Glacier (Medvezhiy Bay, Novaya Zemlya) on cruise 76 of the R/V Akademik Mstislav Keldysh . The specific activities of 137 Cs, 241 Am, 207 Bi, 210 Pb, and 7 Be were measured in 14 samples. Analysis of the materials suggests that cryoconite contains radioactive contamination deposited in the glacier in the period from September 1957 to
