Abstract Results of systematic measurements of radionuclide activity concentrations in the air and deposits from January 1997 to July 2000 near the Ignalina Nuclear Power Plant (hereafter detoted as NPP) are presented. The data on NPP produced radionuclides 60Co and 54Mn in deposits and results of calculation are used for establishment of their distribution near NPP. Water-soluble and water-insoluble radionuclide fractions in the airborne effluents of NPP were investigated. The possibility to evaluate the deposition factor of water-soluble and water-insoluble radionuclides from the NPP jet by comparing the experimental data in the NPP stack and the environment is shown.
