ACCUMULATION OF RADIOSTRONTIUM BY BACTERIAL CELLS
Similar to other aquatic organisms, bacteria are capable of accumulating considerable amounts of strontium-90 from the water polluted with the isotope. In an hour the microbic cells become 10 to 100 times more radioactive than the surrounding medium, and, consequently, they are an important lick in the food chains by means of which radioactive strontium may reach the body of men and animals from the polluted water basins. It was noted that the smaller concentration of bacterial suspension and the lower the specific activity of medium, the higher the coefficient of radiostrontium accumulation in bacterial cells. However, irrespective of the concentration of microbes, the bacterial suspension extracts from the liquid medium an average of 10% of strontium-90. Therefore bacterial and activated sludge may not be successfully used for the removal of this isotope from the radioactive wastes and effluents. The process of physico-chemica; adsorption is most probably the basis of the strontium accumulation in bacterial cells. (Public Health Eng- Abstr., 41: No. 8, 1961)
