We analyzed the fractal dimension of the common reed leaves collected in the Chornobyl exclusion zone in conditions of chronic radiation exposure. On a macroscopic level, the fractal dimension was calculated for images of leaves taken from an optical scanner. On a microscopic level, it was calculated for images obtained from a scanning electronic microscope at 100× and 500× magnification. Statistical analysis showed the dependence of fractal numbers on morphological parameters of leaves on macroscopic and microscopic levels. We found a direct correlation of the fractal dimension of the images to the content of phosphorus and nitrogen compounds in water reservoirs, and a regenerative connection with internal exposure doses, depending on the physical and chemical forms of radionuclides incorporated in the leaves. The results showed the prospect of the application of the fractal analysis of the leaves as an integral figure in the diagnosis of environmental quality.
