摘要：
During the 1974-1987 period 12 paceful nuclear explosions were conducted in the Republic of Sakha (Yakutia). For the first time Pu-239,Pu-240 and Pu-238 concentrations were determined in samples of sails, bottom sediments and lichen taken at the ''Craton-3'' and ''Crystal'' nuclear explosion sites. At the ''Craton-3'' Pu-239,Pu-240 concentrations in the range 6.2 mBq/g to 5.9 Bq/g samples of soil and Pu-239,Pu-240, concentrations up to 7.4 Bq/g in samples of lichen were observed Pu-239,Pu-240 concentration measurements in bottom sediments of a stream washing out the banking around the borehole of ''Craton-3'' show that plutonium migrates in the direction of the Markha river. At the ''Crystal'' site local plutonium concentrations up to 35 Bq/g in soil and 1.8 Bq/g in lichen were observed.
