Radiological consequences resulted from aircraft fall have been considered for the sites of former coastal technical naval bases handed over to Minatom for remediation. At present technical sites “Sysoeva bay” and “Gorbushechya bay” are considered as “DalRAO” facilities. Carrier-plane and anti-ship missile were taken as the aircrafts. It has been indicated that basic mechanism of radioactive cloud generation after jet fall is a fire of fuel remaining on the board. Fire results in resuspension of surface contamination from the area of 26 meters in diameter. Release from missile explosion consists of fine-grained particles of destructed substance. Dimension of explosion crater was used to assess the release quantitatively. Following buildings were taken as potential sources of radioactive release: spent fuel storage (building 30) and solid waste storage (building 31) at the site “Sysoeva bay” and solid waste storage (buildings 3 and 16) at the site “Gorbushechya bay”. Assessments having been done indicate that consequences of such accidents can result in evacuation of population from the areas at the distance of dozens kilometer from the source.
