Assessment of Absorbed Irradiation Dose Rate 137Cs by Emerged Plants in Oligotrophic and Eutrophic Water Bodies
ABSTRAKT
Methodical approaches to the calculation of the absorbed radiation dose rate of the emerged plants (helophytes) are proposed with account of heterogeneity of the habitat and the γ-radiation attenuation by the water masses. It was shown that the dose loads on the plant organism caused by 137Cs radiation are 3-7 times higher than only on the above-ground organs. The absorbed dose rate of the helophytes' roots in the investigated reservoirs was 1.5-2 times higher than the rhizomes, and 6-10 times higher than that of the above-ground organs. The contribution of external irradiation to the total absorbed dose was 76-90%.
