A study was carried out on the effect of 1 MeV accelerated electrons on the survival rate of suspensions of Escherichia coli bacteria and suspensions of Aspergillus fumigatus fungi at various initial concentrations and followed by plating on various nutrient media after irradiation. The samples were irradiated in the dose range from 0.15 kGy to 4 kGy. It was established that the concentrations of viable bacterial and fungal cells decreased nonlinearly with radiation dose. The doses required to reduce populations by a factor of 10 ranged from 0.20 kGy to 0.56 kGy for Escherichia coli at initial concentrations of 10 3 CFU/g to 10 5 CFU/g when plated on agar Thioglycollate medium; 1.28 kGy and 1.23 kGy for Aspergillus fumigatus at an initial concentration of 10 6 CFU/g when plated on Sabouraud medium and Modified Czapek-Dox medium, respectively.

Radiation technologies are widely used in agriculture to accelerate the sprouting of plants, increase crop yields, improve product quality, and destroy pathogenic microflora. This article assesses the effect of treatment with accelerated electrons in various doses on the germination of wheat and flax seeds, as well as on their phytosanitary state. It was established that the most efficient dose for flax variety Severny is 10 Gy, since this dose not only showed the most considerable increase in the germination rate by 38% but also decreased the number of fungi in seeds by 15 % and reduced the average diameter of the remaining colonies by 30% or more. For spring wheat variety Novosibirskaya 29, however, the doses which would be able to significantly reduce the number and the diameter of colonies without causing the inhibition of seed germination were not found.

The necessity of developing safe methods of processing food products which improve the quality and extend their shelf life entails further scientific research aimed at increasing the efficiency of radiation processing of food products. Ionizing radiation causes lipid peroxidation in the items with a high fat and water content, such as chilled meat and fish products, which leads to formation of organic volatile compounds that render the food the specific flavor and smell. Gas chromatography-mass spectrometry is a technique that provides identification of chemical changes that actually occur in the product after irradiation. Experimental data on the content of organic volatile compounds in chilled turkey and salmon meat samples exposed to irradiation with 1 MeV accelerated electrons in the dose range from 0.25 to 2 kGy revealed both common and different trends in the behavior of dose dependences of alcohol, aldehyde and ketone contents in various types of chilled products. A proposed mathematical model based on the possibility of simultaneous occurrence of two competing processes, i.e., the decomposition of compounds due to their oxidation and the accumulation of compounds due to oxidation of other compounds after exposure to ionizing radiation match a dose dependent character of experimental data.
