Objective of this study is to increase the efficiency of disinfecting biological materials and prevent dangerous infectious diseases caused by pathogenic microorganisms by exposing biological objects with pulsed radio emission. To achieve this goal an experimental setup has been developed, manufactures and tested, which makes it possible to study the processes of the effect of pulsed radio emission on biological materials. For irradiation we used pulsed magnetrons with an operating frequency of 2,45 ± 0,05 GHz, which is allowed for bio-medical research. The method is based on the idea of optimal control of the electro physical parameters of the irradiated radio signal, depending on the type of the irradiated object. The developed experimental setup generates pulsed radiation with an adjustable power in the range of 0,1...10 kW. The pulse repetition rate with a duty cycle of 500...10000 is 0,1…5 kHz. The setup has an operating chamber where the test sample is placed, as well as additional components of magnetron protection and measuring the parameters of the microwave power incident on biological object. The setup has been successfully used to irradiate various food samples with pathological micro flora (Salmonell spp etc.). with pulsed microwave radiation. In particular, as shown by the studies, the number of pathological bacteria in the irradiated sample of minced meat decreased by 27,5 times after 28 days compared with the control group of non-irradiated samples. It is planned to continue the experiments started in the field of investigation the effect of microwave radiation on the process of cell division and other aspects of electromagnetic field influence on pathological microorganisms.
