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