ABSTRACT
Introduction: The iDose 2 dosimetry system is a tool for assessing the doses of internal irradiation of workers under the current individual dosimetry control (IDC). In this system, according to a series of measurements of the activity of radionuclides in biological objects (including those not exceeding the detection limit of the measurement technique) and information on contact times and types of compounds, estimates of the committed effective dose equivalent (CEDE) of internal irradiation, as well as their uncertainties, are made based on the Bayesian approach. It is possible to integrate practically any biokinetic models of the behavior of radionuclides in the human body, presented in the form of a system of ordinary differential equations (ODEs) with constant transition coefficients between compartments, into the iDose 2 dosimetry system without changing the source code.
Purpose: Integration of new combined biokinetic models for the list of radionuclides: H-3, Sr-90, Cs-137, Pu-238, Pu-239 and Am-241 from Publications 100, 130, 134, 137 and 141 of the ICRP (conventionally called the series Occupational Intakes of Radionuclides (OIR)), for ingestion and inhalation routes of intake with AMAD = 1 and 5 microns.
Material and methods: For each variant of the biokinetic model, the functions of retention/removal of radionuclides were found through the eigenvectors and eigenvalues of the matrix describing the ODE system.
Results: A total of 65 new biokinetic models and 180 functions of radionuclide retention/removal in the form of a sum of exponents were integrated and quality control was carried out.
Keywords: internal exposure, biokinetic model, individual dosimetry control, Occupational Intakes of Radionuclides (OIR), ICRP, dosimetry system iDose 2, integration of models

ABSTRACT
Purpose: Study of the radioecological situation around mine No. 6 of PJSC ‘Priargunsky Industrial Mining and Chemical Association’ named after E.P. Slavskiy" before commissioning.
Material and Methods: During the radiation survey, to measure the ambient dose equivalent rate, the pedestrian gamma survey method was used using the portable spectrometric complex MKS-01A ‘Multirad-M’ (Russia) and the dosimeter-radiometer MKS-AT6101s (Belarus). To study the specific activity of radionuclides in the soil, samples were taken in accordance with GOST 17.4.3.01-2017. The activity of gamma-emitting radionuclides was measured on a stationary gamma spectrometer manufactured by Canberra (USA). The activity of 210Po and 210Pb was measured on the radiometric system UMF-2000 (Russia) after their radiochemical extraction from samples. Dose assessment of exposure to biological objects was made using dose coefficients established in ICRP Publication 136, considering recommendations R52.18.820-2015.
Results: The results of the study showed that the ambient dose equivalent rate of gamma radiation varied in a wide range from 0.1 to 4.9 µSv/h. The average value in the background areas is 0.14±0.02 µSv/h. The specific activity of natural radionuclides outside the rock dumps, except for 40K, in some areas exceeds the background values up to 10 times. The ecological risk for the considered terrestrial biological objects (grass, shrub, soil worm and mouse-like rodents) does not exceed 10‒2.
Conclusion: There are areas on the territory with traces of anthropogenic activity, which led to man-made radiation contamination. The highest levels of ambient dose equivalent of gamma radiation occur near rock dumps. The rest of the territory has local areas with radioactive contamination. Doses of exposure to biological objects don’t have a significant effect on the incidence, reproduction, and life expectancy of terrestrial biological objects.

ABSTRACT
Purpose: To analyze the existing in NRB-99/2009 and proposed in the journal “Medical Radiology and Radiation Safety” interpretations of the terms “dose limit” and “radiation accident” when developing a new version of this regulatory document.
Material and methods: The features of the interpretation of these terms are considered both in NRB-99/2009 and in a number of domestic and international reference books and glossaries on radiation safety, including proposals published in No. 4 of the journal “Medical Radiology and Radiation Safety” for 2023.
Results: The interpretation of the numerical values of the dose limits proposed in the indicated journal seems to be poorly substantiated, while their traditional interpretation remains more preferable. The addition of the concept of a radiation accident with the term “emergency” with its own explanation by the authors of the article contradicts the recommendations of the IAEA. The necessity of taking into account the specifics of radiation accidents in medicine when interpreting the term “radiation accident” is shown.
Conclusions: 1. There is no need to revise the traditional interpretation of the numerical values of dose limits. 2. It is expedient to replace the wording of the concept of a radiation accident existing in NRB-99/2009 with the wording of the same concept from the IAEA glossary on radiation safety. 3. Taking into account the need for a correct interpretation of the concept of a radiation accident in medicine, the terms “radiation incident”, “unintentional (accidental) medical exposure” and “radiation accident” with their corresponding interpretations should be added to the new version of the NRB.
Keywords: radiation safety standards, dose limit, radiation accident, interpretation of terms

ABSTRACT
Purpose: To discuss the case of oppositely directed influences of the indicators of crystallized and fluid intelligence in the decisive rule designed to predict the professional success of the nuclear power plants (NPPs) operators.
Material and methods: This paper analyzes the results of psychodiagnostic examinations of operators of main control rooms (MCR) of NPPs that functioned under normal conditions. All individuals were administered the J. Raven’s “Progressive matrices”, the Russian language adaptation of the Minnesota Multiphasic Personality Inventory (MMPI) and the Sixteen Personality Factor Questionnaire (16PF, form A). A cross-expert review using the ranking method revealed two groups of operators with relatively higher and lower levels of professional success. The method of canonical correlation analysis has been used to obtain the best linear discriminator for predicting the professional success of MCR operators based on indicators of psychodiagnostic tests.
Results: Based on the results of the expert assessment, two groups of operators with the highest and lowest professional success were identified. Decisive rule were obtained that make it possible to predict the professional success of operators based on a system of signs (values of the psychodiagnostic tests scales multiplied by coefficients) after the data processing using canonical correlation analysis. Unexpected result was that the high values of 16PF factor «B» turned out to be «undesirable» for the prediction of professional success, that is, these values increased the probability of assigning the operator to the group of the lowest successful specialists.
Conclusion: Factor «B» of 16PF was considered as a tool for assessing predominantly crystallized intelligence, and the Raven’s test – for the fluid one. At the same time, there are no methods that allow measuring these indicators in their purest form. Taking this fact into account, the author believes that the true role of factor B in the decisive rule did not reflect the undesirability of advanced crystallized intelligence among MCR operators. It is most likely that its opposition to the «desirable» indicator (the number of correctly solved tasks of the Raven’s test) made it possible to single out the role of fluid intelligence (or some of its lower-level aspects) as a professionally important quality for the particular operator activity.

ABSTRACT
Purpose: to study the features of the state of the bone marrow according to cytological and histological studies at different periods of the course of CRD, caused by exposure to different dose rates, which developed as a result of professional prolonged exposure in a cohort of former employees of a radiation hazardous enterprise who underwent inpatient examination at the clinic of the A.I. Burnazyan Federal Medical and Biomedical Center in the period up to 1995.
Material and methods: the study of the results of cytological and histological studies of the bone marrow was carried out in former workers of the Mayak Production Association who were exposed to long-term industrial exposure with a dose rate of 0.008−0.07 Gy / day
(15 people), 0.003−0.007 Gy / day (12 people) and less than 0.001 Gy/day (25 people), during periods of formation, outcomes, immediate and long-term consequences of CRS. At the stage of studying the results of histological examination of the bone marrow, 54 more patients with CRS were added to the third group, irradiated with a dose rate of less than 0.001 Gy / day.
Statistical processing of the material was carried out using the IBM SPSS Statistics software package.23 using the Kruskal‒Wallis test and the Mann‒Whitney U-test for independent samples. The results obtained were considered statistically significant at p < 0.05.
Results: At a dose rate of 0.008−0.07 Gy / day during the formation period, the myelogram revealed narrowing of the granulocyte and expansion of the red germs, acceleration of maturation of granulocytes with a normal erythrocyte maturation index and leuko-erythroblast ratio. In peripheral blood – agranulocytosis. In the period of outcomes and immediate consequences − narrowing of the granulocytic, expansion of erythrocyte germs, acceleration of maturation of neutrophils with other myelogram parameters within normal limits. In the blood − agranulocytosis, anemic syndrome. In the long term, in the case of restoration of hematopoietic function, narrowing of the granulocytic germ with other myelogram parameters within the reference values. However, with a similar course of CRS in 60 % of patients in periods of outcomes and long-term consequences, the development of myelodysplastic syndrome with transformation into acute leukemia or aplastic anemia is possible.
At an irradiation dose rate of 0.003−0.007 Gy / day in the period of CRD formation, the myelogram revealed an expansion of the granulocytic germ, with other indicators within the normal range. In the period of outcomes and immediate consequences, an acceleration of maturation of granulocytes and an increase in the leuko-erythroblastic ratio were found. In the long term, a narrowing of the granulocytic and expansion of the erythrocyte sprouts, a slight acceleration of the maturation of granulocytes were found. Hystological examination: polymorphocellular bone marrow – in 11 out of 25 patients, hypoplasia – in 9 out of 25, signs of hyperplasia – in 5 out of 25. In the long term, 2 patients from this group developed oncohematological diseases.
At an irradiation power of less than 0.001 Gy / day, during all periods of CRD, normal values of granulocytic and erythrocyte sprouts were noted in the myelograms of patients. In the period of CRD formation, the normal size of the granulocytic germ was achieved due to the accelerated maturation of neutrophils. The leuko-erythroblastic ratio in the period of long-term consequences was significantly higher than the norm (5.29 and 4.5, respectively). Hystological examination: 32 out of 64 patients had polymorphocellular bone marrow, 22 out of 64 had hypoplastic bone marrow, 7 out of 64 had bone marrow hyperplasia.
Conclusion: regular changes in hematopoietic tissue and peripheral blood in CRD can serve as diagnostic criteria, based on which it is possible to assume the dose rate of radiation to which the patient was exposed, and also on their basis, it is possible to predict the outcome and long-term consequences of CRD that developed as a result of this exposure.
