Environmental Monitoring of Atmospheric Air Pollution with Radionuclides Using Moss Bioindicators

The purpose of our research was to identify the degree of air pollution with radionuclides using moss bioindicators. We studied samples of moss and soil (near Mingechaur, Baku) to identify the bio-indicator properties of moss and for bioindication of air and soil. We studied samples of moss, soil and water near Mingechaur city and Baku city regions. The activity of radionuclides were determined on Gamma spectrometer. Determination of content and activity of the radionuclides in the tests of soil, plant and water, was carried out at "Canberra" (USA)γ-spectrometer with high a purity germanium detector (HP Ge). It was determined the activity of radionuclides (7Be, 40K, 60Co, 208Tl, 134Cs, 137Cs, 210Bi, 212Bi, 212Pb) in the samples of of moss, soil and water samples taken from the Mingechaur region and in Baku region of the Azerbaijan Republic. As a result of the research it was revealedе the activity of 40K was more than other isotopes (648,1 Bq/kg). It was found out 7Be of activity 79.08 Bq/kg, 214Pb of activity 62.62Bq/kg, 214Bi of activity 28.74 Bq/kg, 137Cs of activity 14.01 Bq/kg, 134Cs of activity 12.15 Bq/kg, 60Co of activity 11.34 Bq/kg and oters, which were more in Mingechaur region than in Baku.
