Abstract Intensive development of foreign economic relations, a significant increase in the number of their participants, and the changes in customs policy in the context of the emergence of a market economy require the customs services to ensure high-performance, effective customs control of goods, vehicles, and belongings of people traveling across the state border. One of the defining integral elements in the daily inspection work of customs operatives is their use of technical means of control, without which it is now impossible to ensure the timeliness, quality, and culture of control at the border. The operational tasks of the customs services, requiring the use of technical means of customs control, are fundamental for understanding the role and place of the operational activities in the customs services. The issue is worth discussing, thus, the given paper will consider the use of electron bremsstrahlung for customs control of drugs at the border. Introduction High efficiency of control is achieved by the complex application of technical means in each specific area of customs control. For checking each kind of object moved across the state border, certain types of technical means must be used. Good knowledge of operational and technical capabilities, modern techniques and methods of their application, mastering practical skills of working with them can ensure a high professional level of customs control, starting with a reasonable calculation of duties and ending with the identification of contraband items. Technical means of customs control is a complex of special means used by services directly in the process of operational control of all types of objects moved across the border. Objects are understood as hand baggage and accompanied luggage of passengers and transport employees, all types of cargo, international mail, international transport vehicles, and, in exceptional cases, specific people (when there are sufficient grounds to believe that they are carriers of contraband goods). Technical means of control are a necessary “weapon” for operational workers of the customs service, the use of which ensures the economic and state security of the country. The given paper will discuss the use of electron bremsstrahlung for control of drugs at the border. Impact of Radiation Scanning is safe for those who cross the border; the consequences may arise for people working with these devices. In medical practice, for hazardous working conditions, specialists who work with radiation receive various wage increases. For a person who undergoes an X-ray screening procedure once a month, it is not dangerous if he or she is outside the vehicle during scanning (Ivashova & Kiida, 2019). As a rule, two people always work at the inspection complexes, and one of them must take the driver and passengers outside the radiation exposure into a safe zone. The equipment is tested annually, and a special examination protocol is issued. The main processes of interaction of X-ray radiation with a substance at the energy of quanta of the electromagnetic field (photons) less than 106 eV are photoelectric absorption and scattering. In this case, the physics of phenomena is compl
