The subject of the research in the article is a mathematical model of the dose absorbed by special clothing. The goal of the work is to improve the mathematical model of the dose absorbed by special clothing irradiated with accelerated electrons. The following tasks are solved in the article: to investigate the possibility of using the improved mathematical model of the dose absorbed by special clothing depending on the frequency of the beam pulses of accelerated electrons, conveyor speed and geometrical parameters of the object, to calculate the technological modes radiation sterilization process. The following methods are used – mathematical physics. The following results have been obtained: the importance of caring for workers' special clothing was noted; the shortcomings of modern disinfection methods were identified and the need for disinfection of special clothing with accelerated electrons using special electron accelerators was justified; it has been established that the main criterion for radiation disinfection is the absorbed dose; the necessity of determining the maximum allowable dose using the mathematical model was justified. An improved mathematical model of the dose absorbed by special clothing makes it possible to calculate the irradiation modes of various materials of special clothing that differ in size, shape and physical properties, which will allow us to develop a system of regulatory regimes for radiation-physical disinfection of work clothes and ensure legislative and regulatory requirements for occupational health. The normative regimes of the process of special clothes disinfection are calculated in the form of the dependence of the absorbed dose depending on the pulse repetition rate and the conveyor speed. Conclusions: the mathematical model of the dose absorbed by special clothing was improved depending on the frequency of the pulses of the accelerated electron beam, the conveyor speed and the geometric parameters of the object. It was used to calculate the regulatory technological modes of the process of disinfection of special clothes.
