Abstract
The optical properties of the unirradiated and irradiated series of biomaterials of the lake-reservoir Sorbulak were investigated. Samples are made from biomaterials of Sorbulak Lake (polluted) and growing near a nearby flowing river (unpolluted). The study of the optical properties and structure of irradiated and non-irradiated samples of reeds, sedges for reflection and lumen was carried out on an automated digital microscope (ACM) of the type Leica DM6000M. Experimental samples were prepared in the form of tubes (cut from stems) and leaves. The dose of electron irradiation is 50–500 kGy. Analysis of the data showed that simultaneous contamination and electron irradiation of biomaterial samples leads to blurring of material bands, which is associated with the accumulation of heavy metals and the generation of resistant radiation defects such as a Frenkel pair and an electron-ion pair, which subsequently lead to cell destruction and destruction of the biomaterial.
