radionuclides. 



2. Kratok-3 - was accompanied by an accidental release of radionuclides onto the surface (2% 



of the total of the decay products from the nuclear charge with a yield of 20 kilotons). 



3. Sheksna and Neva-2 ~ area contamination by radionuclides during technological tests from 



combustion of gas.
