Analysis of radioecological situation was performed for the territories located near the radioactive waste storage sites of the «North-West Territorial District» Leningrad branch of FGUP «RosRAO». The planned annual dose from the regular releases is estimated to be 1,1·10-4 mSv/year, which is two orders of magnitude lower than the level of negligible radiation risk. At present, annual doses are considerably lower than the permissible dose limits; they do not exceed 1-2% of the natural radiation background. Hypothetical scenario of radiation accident was developed; it was shown the absence of territories where obligatory measures of radiation protection of population should be applied in the case of such scenario. Outside the working areas dose rates to biota do not exceed the natural background levels.
