The samples were analyzed at the Institute of Plant and Animal Ecology of the 

 Ural Regional Division of the USSR Academy of Sciences at the Department of 

 Continental Radioecology in the town of Zarechny in Sverdlovsk Oblast The level of 

 cesium isotopes was measured on the AM-A-02F1 multichannel analyzer with a 

 semiconductor detector, model DGDK 50-B. The photopeak areas were calculated on a 

 computer; the error was no greater than 3%. In the prepared soil szmiples, the content 

 of strontium-90 was determined from the daughter yttrium-90 where the radiometry of its 

 precipitates was conducted on the low background lJMF-1500 unit with the end-window 

 counter SBT-16, where the reading error was no greater than 15%. 



The results of the analyses are presented in the form of a table.
