“…The activity concentration 6.4 Â 10 À5 Bq l À1 of 239,240 Pu was attributed to possible leakage, since this result as much as twice exceeded maximal background values typical of the fresh water environment. Yu-Fu et al (1991) provide an environmental level of 239,240 Pu activity concentration in lake water having the range of (0.1-29) Â 10 À5 Bq l À1 . Plutonium penetration to groundwater was clearly confirmed by the measurement in the sample taken on 18 September 2006, when a five-times increase in activity concentration of 239,240 Pu was demonstrated than 27 June 2005 ( Table 2).…”

“…The concentrations of plutonium in the water of Lake Dru kšiai and in the wastewater discharged from the Ignalina NPP have never been measured. However, Yu-Fu et al (1991) determined that the concentration of plutonium in freshwater lakes fluctuated from 1 ϫ 10 Ϫ7 to 2.9 ϫ 10 Ϫ5 Bq/L. Meanwhile, in river water, the concentration of plutonium fluctuated from 6 ϫ 10 Ϫ7 to 1.9 ϫ 10 Ϫ6 Bq/L (Hirose et al, 1990).…”

The genotoxic effects on Tradescantia of (137)Cs, (90)Sr, and (236, 242)Pu, a heavy metal mixture [Cd, Cr(VI), Cu, Mn(II), Ni, Pb, Zn] and of a complex mixture of these toxicants were determined. The impact of radionuclides on plants subjected to ionizing radiation exposure was estimated. The number of somatic mutations and the quantity of nonviable stamen hairs were used as end points in the testing. An increase in the quantity of nonviable stamen hairs was observed with increasing internal exposure to (137)Cs, (90)Sr, and (236, 242)Pu; however, the number of somatic mutations was not observed to be dependent on ionizing radiation. The internal dose of individual radionuclides necessary to decrease the quantity of viable stamen hairs in Tradescantia by 50% can be arranged in the following sequence: (236, 242)Pu > (137)Cs > (90)Sr. Tradescantia died in the mixture of the radionuclides (90)Sr, (137)Cs, and (236)Pu (5 x 10(-2), 7 x 10(-5), and 4 x 10(-10) Gy, respectively) after 14 days, whereas the heavy metal mixture caused somatic mutations in 3% of the Tradescantia and nonviable stamen hairs in 7% but no mortality. However, the Tradescantia died in a combined mixture of these heavy metals and the radionuclides after 14 days. On the basis of all these observations, it can be concluded that the toxic effect of radionuclides was more significant than that of heavy metals.
