During 2000, observations under the framework of control of radioactive contamination were continued at 34 sites of the State System of Radiation Monitoring in the Russian Arctic. At all stations, daily monitoring of exposure dose strength of gamma emissions, and daily sampling of radioactive fallout from the atmosphere to determine total beta-activity are conducted. At sites in Arkhangelsk, Naryan-Mar, Salekhard, Murmansk, Dikson Island, Zhelaniya Cape, Kheis Island and Kandalaksha, sampling of atmospheric aerosols and precipitation was performed for specific radioisotopic analysis, including determination of tritium. Samples of surface water for determination of levels of 90-Sr and tritium were collected at radioactive contamination control stations in the mouth regions of the largest rivers of the Russian Arctic (Severnaya Dvina, Pechora, Mezen, Ob, Yenisey, Khatanga, Indigirka). 26 samples were collected for this purposes in 2000. Samples for determination of 90-Sr in seawater were collected at relevant sites in the Barents Sea and White Sea.
