Using algaflora in the sediment as indicacators of radioactive contamination in rivers of Lugansk city
Abstract
The article discusses the use of algaflora in the sediment of river Lugan as indicators of water pollution with radionuclides. It is found that the constant absolute indicators of a certain level of specific activity of radionuclides 226Ra, 232Th, 137Cs, 40K are those genera of algaes like Volvox, Cymbella, Gomphonema, Chroociccus. Permanent indicators on the content of 226Ra, 232Th, 137Cs, 40K in river silt revealed algae genera Chlorococcum, Chlorella, Pandorina, Pinnularia, Navicula, Oscillatoria. Based on the calculated regression equations for the number of algae sediments can predict the specific activity of these radionuclides.
