ABSTRACT
Purpose of the work is to justify the safety in the operation of radiation sources in the center of nuclear medicine. The paper reflects the advanced methods of nuclear medicine using radionuclides, used at the site of the Features of Ensuring Radiation Safety in the FSCCRO of FMBA of Russia, for the purpose of diagnosing and treating malignant neoplasms. At the same time, a necessary condition is to ensure the radiation safety of medical personnel, as well as compliance with the requirements and standards governing the safe operation of radiation hazardous facilities. The paper presents an analysis of individual effective doses of medical personnel of group A of the nuclear medicine center for the period 2020-2022, as well as the risks of stochastic effects during exposure to an average individual dose for personnel of group A.
Results: Conclusion: a feature of the Features of Ensuring Radiation Safety in the FSCCRO of FMBA of Russia is a large concentration of radiation-hazardous objects on one site, which implies the fulfillment and observance of radiation safety requirements. The analysis of individual exposure doses for group A personnel indicates that the established control and permissible levels are not exceeded. At the same time, measures are proposed to optimize (reduce) the radiation load on medical personnel working with sources of ionizing radiation. The unique experience gained by the Center can be replicated when carrying out work to ensure radiation safety standards for newly built and existing medical institutions in Russia in order to provide high-tech medical care in the field of nuclear medicine.
Keywords: nuclear medicine, radiation safety, individual radiation dose, risk of stochastic effects, radionuclide sources

ABSTRACT
Purpose: Assessment of the role of various factors in the formation of radioresistance is an important section of radiobiology, radiation medicine, including radiation therapy for hematological oncological diseases. The quality of drinking water, as it turned out, can significantly affect the radio resistance. Against the background of studying the antiradiation properties of various types of water, differing in mineral and isotopic composition, the problem of the influence of tap water on the course of radiation injury remained underestimated. This circumstance determined the purpose of the work: to compare the effectiveness of the effect of fractionated total X-ray irradiation in lethal doses, simulating total therapeutic irradiation of oncohematological patients, when consuming tap water and highly purified artificially mineralized tap water in an experiment on mice.
Materials and Methods: Female ICR (CD-1) mice were irradiated with moderately lethal doses of fractionated (daily 4 × 2.2 Gy
and 4 × 2.3 Gy) X-ray irradiation. After exposure, half of the mice received tap water as drinking water, and the other half received artificially mineralized drinking water.
Results: Keeping animals on tap water statistically significantly reduced the survival rate of mice under fractionated irradiation (χ2 = 3.88, p <0.05, log-rank test p = 0.049) compared with animals receiving artificially mineralized distilled water. In addition, in the group of mice that received tap water, an increase in the rate of death of mice and a lower safety of the group weight of animals during the development of acute radiation injury were noted.
Conclusion: Tap water, used as drinking water, increases the damaging effect of radiation with fractionated X-ray irradiation of mice.
Keywords: X-ray exposure, tap water, artificially mineralized distilled water, survival, mortality, mouse

ABSTRACT
Purpose: To present an analysis of the current state of the Russian legal, standard, and methodical regulatory framework of the radiation safety in comparison with up-to-date international recommendations and to propose further ways to improve it.
Results: Management of the radiation safety has three levels - legal, standard and methodical. The up-to-date international system for management of the radiation safety is based on the documents of the UNSCEAR, ICRP and IAEA, which are used in national legal, standard, and methodical systems on a voluntary basis.
The accumulated more than seventy-five years of experience in the widespread use of nuclear technologies shows its safety. The experience of mitigation of the radiation accidents that took place in the USSR and in Russia, including the largest one - the Chernobyl accident, leaves no doubt that the current system for management of the radiation safety is effective under normal operation of radiation facilities and in emergency situations.
At the same time, the analysis shows that the Russian legal, standard, and methodical regulatory framework is based on the concepts, standards, international recommendations of the 1990s. Therefore, regarding many important aspects, they do not correspond to the up-to-date international radiation protection system and they are needed to be harmonized with international approaches in this area.
Conclusion: First of all, it is necessary to develop a new federal law “On radiation safety in the Russian Federation” and after that, on its basis, to prepare new documents of the federal level: Radiation safety standards and Basic rules for management of the radiation safety. At the next stage, labour-consuming processing of the regulatory documents of the standardization system in the field of management of the radiation safety of workers, public, patients and the environment is needed to be carried out.

ABSTRACT
Purpose: To analyze the existing computational methods for estimating aerosol losses in sampling systems at nuclear energy use facilities, presented in domestic and foreign regulatory documentation and technical literature, in order to form proposals for practical optimization of the use of these computational algorithms.
Results: Methods for calculating the loss of aerosol particles in air sampling systems from pipes, ventilation systems and premises of nuclear energy facilities are considered. A comparative analysis of methods for estimating aerosol losses considered in Russian and foreign regulatory and technical documentation is performed. The basics of aerosol mechanics are briefly considered. On the basis of the conducted research, the possible applications of the considered methods for estimating aerosol losses in the design for various initial situations are considered. The expediency and prospects of developing clear computational algorithms for use in the design and operation of sampling systems are considered
Keywords: sampling system, radioactive aerosols, aerosol losses, isokinetics, gravitational deposition, sedimentation, inertial deposition, turbulent deposition, diffusion deposition
