Summary

A content of 129I is certain in the radioactive water (RW) selected from the apartments of object Ukryttya. Activity of isotopes of iodine was determined by γ-spectrometry measuring of the faction of iodine, selected from RW on the transmitter of stable iodine. Concentration and cleaning of isotopes of iodine from present in RW of γ-emitting radionuclides of 137Cs, 154,155Eu and 241Am made by an extraction method. A volume activity of 129I in the investigational tests of RW is 5.3 ± 2.1 Bq/l. Ratio of activity in RW 90Sr/129I – (2.6 ± 1.3) ∙ 106 and 137Cs/129I – (5.7 ± 1.8) ∙ 106.  In the tests of water directly flowing through the apartments with fuel-containing materials with the high concentration of uranium, selected from the mining hole of U-9-B, short live isotopes of iodine 131, 132, 133, 135I not found.

Keywords: 129I, extraction, liquid radioactive waster, object Ukryttya.
