Accumulation of /sup 90/Sr and /sup 137/Cs by four types of bottom sediments of a freshwater lake (sandy, peaty, lime and sapropel) are studied under natural conditions. It is established that /sup 90/Sr content in the sediments varies from 30 to 2300 pCi/kg (on a dry weight basis), and accumulation coefficients from 75 to 600. /sup 9/..sigma..r is absorbed mostly by peaty ground, and to the least extent by sandy one. /sup 137/Cs content in ground is within the limits of 1700 to 3000 pCi/kg, and accumulation coefficients are 2000 to 4200. The highest degree of /sup 137/Cs adsorption is registered for sapropel, which is due to its smaller particle size.
