Radioecological Research Research Articles

Трансформация радиоактивного загрязнения донных отложений Калининградского залива в период 2011–2023 гг.

The article presents the data of radioecological research of the bottom sediments in the Russian zone of the Vistula Lagoon in 2011–2023. According to research, the specific activity of 137Cs in the bottom sediments of the Lagoon was in the range of 3,9–165 Bq/m3. 137Cs is the main technogenic radionuclides that makes the greatest contribution to the pollution of the Lagoon. Contamination of the bottom sediments with 137Cs is determined by the redistribution of mainly post-Chernobyl fallout. The 137Cs accumulation was recorded in the northern deep-water part of the Primorskaya Bay. According to observations, the effective half-life of 137Cs activity in the sediments of the Lagoon is 10,4–42 years. The content of natural radionuclides is: 226Ra – from 9,0 to 35,3; 232Th – from 3,8 to 43,2; 40K from 227 to 715 Bq/kg. The NRN specific activity in the sediments of the Lagoon did not exceed 153 Bq/kg, which was significantly lower than the established safe level (370 Bq/kg), allowing their handling without restrictions. The correlations between the content of 40K, 226Ra, 232Th in the bottom sediments of the Lagoon were established with the type of sediment

From crisis to recovery: scientific endeavors of the Institute of Agroecology and Environmental Management of the NAAS of Ukraine in minimizing the consequences of the Chornobyl accident

The participation of scientists from the Institute of Agroecology and Nature Management of the National Academy of Agrarian Sciences of Ukraine in mitigating and minimizing the consequences of the Chornobyl disaster during 1986–2024 is elucidated. It is demonstrated that the history of the development of radioecological research at the Institute originates from the early days following the Chornobyl Nuclear Power Plant accident. Actually, from this time onwards, the monitoring of radiation in agricultural lands affected by accidents has begun. One of the most crucial directions of work during this period was conducting of aerial and ground radiation reconnaissance. Active efforts were made in radioecological monitoring and dosimetric control of the population. The radioactive contamination of the territory was analyzed based on landscape, basin, and landscape-geochemical principles, upon which maps of radiation contamination of the territory for 137Cs, 90Sr, and 94Pu were compiled. During the remote period of Chornobyl disaster aftermath, the team of the unit was engaged in developing countermeasures for various types of economic activities in conditions of radioactive contamination, taking into account modern trends in the development of the natural-economic complex and new economic conditions based on landscape-ecological approach. Analysis of the results of scientific activities of the institution’s staff indicates that during the post-accident period, the team of radioecologists gathered and systematized significant volumes of information, which were transformed into various databases, cartographic materials, mathematical models, methodological recommendations, regulations, drafts of normative documents, and so forth. Information was provided on the contribution of the Institute’s employees to the development of radioecology, restoration of agricultural production on radioactively contaminated lands, and rehabilitation of territories affected by the Chornobyl Nuclear Power Plant accident. Furthermore, contemporary radioecological problems and threats posed by the full-scale military aggression of Russia against Ukraine were outlined, including its violation of all seven principles of radiation safety, as well as potential radiation-related hazards in the future.

Development and validation of a Medaka fish voxel-based model for internal ionizing radiation dosimetry

In this paper, we present a voxel-based phantom of Medaka fish that can be used to assess the internal radiation doses that would be absorbed by different organs of this fish species if exposed to radioactive wastewater released into the ocean. The geometric model for fish was generated based on available Wavefront Object files for smooth-bodied Medaka fish organs, whereas due to the lack of Medaka fish material specification, the material model was constructed using material data appropriate to ICRP 110 adult male voxel-based phantom. Absorbed Fractions (AFs) and Specific Absorbed Fractions (SAFs) were calculated for eight organs of major interest as sources and for each organ as target at a set of discrete photon, electron, alpha and neutron energies. To validate the present model the calculated AFs in the studied organs were compared to ones obtained in similar organs in a voxel-based phantom of another teleost fish species called Limanda limanda. The results presented are consistent with the reference dosimetric data. We concluded that the Medaka model can be used in radioecology research to improve marine radiation protection.

Some aspects of returning radioactively contaminated lands in Polissіa region of Ukraine to agricultural use

The article highlights the natural-climatic and socio-economic retrospective prerequisites for the return of radioactively contaminated lands in Polissіa, Ukraine to agricultural use. The necessity of using modern methods and means of radioecological research to assess the radioecological state of land for the development of strategic management documents is demonstrated. The research carried out at the Institute of Agroecology and Environmental Management of the National Academy of Agrarian Sciences of Ukraine during the period of 2020–2023 utilized interdisciplinary scientific methods including analysis and synthesis, retrospective and comparative analysis, analytical-synthetic (study of scientific and statistical data, legislative and founding documents, etc.), and mathematical-statistical methods. The analysis of the socio-economic situation was carried out based on official statistical data from the main statistical departments in Volyn, Zhytomyr, Kyiv, Rivne, and Chernihiv regions. The estimated levels of radionuclide contamination of the territory were obtained based on official data from the State Enterprise «The Institute of Soil Protection of Ukraine». Radioecological-landscape mapping was carried out using the open-source software QGIS. The aim of the research was to substantiate the scientific basis for the rehabilitation and sustainable use of radioactively contaminated territories in Ukrainian Polissia region in the context of green economy to minimize the domestic food crisis. It has been demonstrated that the soil characteristics and vegetation cover of Ukrainian Polissia region contribute to the contamination of agricultural and forest products with radionuclides, which is a specific problem for the region. The most radiologically hazardous ecosystems for the release of radionuclides into the products are over-moistened meadows and pastures, forested areas, as well as agroecosystems on organogenic soils. Global climate change and the consequences of Russian military aggression are significant modifying factors for all previously existing environmental and socio-economic challenges. This necessitates the implementation of comprehensive measures for the rehabilitation of the region, preceded by monitoring studies and the development of appropriate strategic planning documents. Based on the results of a retrospective analysis and calculations, it has been established that, provided recommended agricultural measures are implemented, the restoration of effective agricultural production is possible throughout the territory of Ukrainian Polissia. It has been demonstrated that the comprehensive rehabilitation of Ukrainian Polissia depends primarily on the eco-economic efficiency of agricultural production, which requires a clear differentiation of agricultural activities in accordance with a range of ecological, economic, and social factors, as well as the improvement of agricultural production scenarios. A method for complex radioecological-landscape mapping of radioactively contaminated lands of Ukrainian Polissia has been developed. This method involves a landscape approach that integrates data from a series of thematic maps

Adverse outcome pathways (AOPs) for radiation-induced reproductive effects in environmental species: state of science and identification of a consensus AOP network

Background Reproductive effects of ionizing radiation in organisms have been observed under laboratory and field conditions. Such assessments often rely on associations between exposure and effects, and thus lacking a detailed mechanistic understanding of causality between effects occurring at different levels of biological organization. The Adverse Outcome Pathway (AOP), a conceptual knowledge framework to capture, organize, evaluate and visualize the scientific knowledge of relevant toxicological effects, has the potential to evaluate the causal relationships between molecular, cellular, individual, and population effects. This paper presents the first development of a set of consensus AOPs for reproductive effects of ionizing radiation in wildlife. This work was performed by a group of experts formed during a workshop organized jointly by the Multidisciplinary European Low Dose Initiative (MELODI) and the European Radioecology Alliance (ALLIANCE) associations to present the AOP approach and tools. The work presents a series of taxon-specific case studies that were used to identify relevant empirical evidence, identify common AOP components and propose a set of consensus AOPs that could be organized into an AOP network with broader taxonomic applicability. Conclusion Expert consultation led to the identification of key biological events and description of causal linkages between ionizing radiation, reproductive impairment and reduction in population fitness. The study characterized the knowledge domain of taxon-specific AOPs, identified knowledge gaps pertinent to reproductive-relevant AOP development and reflected on how AOPs could assist applications in radiation (radioecological) research, environmental health assessment, and radiological protection. Future advancement and consolidation of the AOPs is planned to include structured weight of evidence considerations, formalized review and critical assessment of the empirical evidence prior to formal submission and review by the OECD sponsored AOP development program.

Agile fusion method for the determination of Pu isotopes in diverse sediments

Atmospheric nuclear testing has occurred worldwide resulting in trace amounts of plutonium (Pu) isotopes in soils and sediments across the globe. Soils and sediments can vary greatly in both physical and chemical properties within close geographic regions presenting a major challenge for sample preparation in the analysis of fallout radionuclides. It is vital to have a rapid, agile method for the complete digestion of samples containing refractory Pu particles to address this challenge. A radioanalytical procedure for the analysis of Pu isotopes in soils/sediments has been developed improving sample preparation using fusion. This is done by eliminating the need for pre-dissolution combustion to remove organic material and providing greater application to a diverse range of samples including those of metal-bearing mineralogy. The integration of borate and peroxide flux materials creates a sample dissolution procedure that is greater than the sum of its parts. This method is applicable to the analysis of 239/240Pu in soil/sediment samples with a sample mass of 3 g, ranging from 0.05 to 5000 mBq/g achieving 242Pu tracer recoveries between 50 and 94%, with a trace-level detection limit of 0.04 mBq/g and measurement uncertainties down to 19%; adjustable to measurement priorities with variation in count time, background counts, chemical recovery and total activity of the sample. This sample preparation technique can be utilized with complementary analysis of alpha spectrometry or ICP-MS. Achieving these parameters provides a highly adaptable standard method for 239/240Pu in soil/sediment analysis applicable to samples from radioecological research at trace environmental levels to emergency response scenarios with 48-h turn-around producing highly repeatable, succinct and high-quality analysis.

Advantages of Gamma-Radiometric and Spectrometric Low-Altitude Geophysical Surveys by Unmanned Aerial Systems with Small Scintillation Detectors

Unmanned aerial systems (UAS) for airborne gamma-ray surveys in radioecological and geological research are being increasingly used, since they provide radiation safety for personnel and high survey performance. Improvement of detection modules is one of the main directions in which UAS-gamma is developing. Semiconductor detectors are used increasingly as they have a small mass and are convenient for light unmanned aerial vehicles (UAVs). Simultaneously, in our opinion, the potential of traditional scintillation detectors is not exhausted because they are cheaper and more affordable. Radiometric and spectrometric detection modules based on scintillation detectors can even be created at home. The main disadvantage of scintillation detectors is the need for large crystals with significant mass to obtain high data quality. Traditional aerial gamma surveys with operated aircraft systems use scintillation detectors with a volume of tens or hundreds of litres. In this paper, we present the comparison result of radiometric and spectrometric surveys with small volume detectors made at different altitudes and ground surveys. We prove that with properly designed and applied ultralight UAS for aerial gamma spectrometry it is possible to obtain high-quality and informative data.

Ecosystems of Siberian Arctic Seas–2020: The Kara Sea (Cruise 81 of the R/V Akademik Mstislav Keldysh)

Cruise 81 of the R/V Akademik Mstislav Keldysh was organized by Shirshov Institute of Oceanology and took place from August 27 to September 25, 2020 under the Program “Marine Ecosystems of the Siberian Arctic.” Participants included 76 scientists from the institutes of Russian Academy of Sciences, Moscow State University, VNIRO, and the NRC Kurchatov Institute and specialists from the Emergency Situations Ministry. Coordinated hydrophysical, hydrochemical, biooceanological, geochemical, and radioecological research was carried out over the Kara Sea, on the shelf near the St. Anna Trough, the continental slope, the Novaya Zemlya depression, and bays of the eastern coast of Novaya Zemlya. The condition of disposed radioactive waste in bays of the archipelago was assessed.

Оценка радиоэкологической обстановки на территориях аварийного чернобыльского следа в России (1986-2020)

The current environmental situation in areas located in the “Chernobyl footprint” in Russia is con-sidered in the paper. Radiation contamination in different parts of the “footprint” varies from the maximum level in the exclusion zones to the level close to the background in areas with low level of radioactive contamination. Environmental monitoring data and calculated density of soil con-tamination with radionuclides in the vicinities of residential areas in Bryansk, Kaluga, Tula, Orel and Novgorod regions were used as reference data for assessment of radiation dose rates and ecological risks for the reference biological species: the elk (Alces alces), red-backed mouse (Myodes glareolus), the Archangel fir (Pinus sylvestris), brandling (Lumbricus terrestris), the pike (Esox lucius), and the fresh-water soldier (Stratiotes aloides). The integrated contamination index, that is the sum of ratios of registered radionuclides contamination density to the reference levels, was used as the indicator of territory radioecological safety. The calculation was made in accord-ance with the Roshydromet Recommendations R-52.18.853-2016. The highest doses to the biota and ecological risks were registered in 1986. Radiation dose rates to some vertebrates in the most contaminated districts of the Bryansk region in May 1986 exceeded ecologically safe radiation level of 1 mGy/day. Doses to reference biological species inhabited outside exclusion zones within the period of May-December 1986 were lower than the radioecological safety level. After decay of 131I and other short-lived radionuclides 137Cs became the basic contributor to the biota dose. Radiation dose rate to the terrestrials and radio-ecological safety index gradually decreased due to radionuclides physical decay over the period of 1986-2020. Current radiation doses to the terrestrials inhabited the most contaminated districts were, on average, one order below the safe radiation dose to the vertebrates, two orders below the safety radiation level to the Archangel fir and three orders be-low the safety radiation dose to the soil invertebrates. Current radiation dose rates to inhabitants of the lake of Kozhanovskoe, one of the most contaminated areas due to the radioactive fallout, current radiation dose rates to the lake fish were two orders below the safe level, radiation dose rates to algae were three orders below the safety level, however, they still are above the back-ground level. Current indices of integrated contamination in areas of the Chernobyl radioactive “footprint” are inhomogeneous. Current indices of integrated contamination in the majority of contaminates areas are dozens times and the indices in low radiation contaminated areas are hundreds times lower than ecological safety level. The highest indices occur in a number of dis-tricts of Bryansk region but they are lower than ecological safety level, however in some sites in exclusion zones the indices exceed the ecological safety level. These sites are unique natural testing grounds for radio-ecological research and monitoring of the environment and radiation protection development. In this connection it is recommended to continue long term research and development of radiological protection of the environment.

Radionuclides Content in Tissues and Organs of Pumpkinseed <i>Lepomis gibbosus</i> (Linnaeus, 1758) from the Zaporizhzhia (Dnipro) Reservoir

The article presents the results of studies on the content of artificial (137Cs, 90Sr) and natural radionuclides (226Ra, 232Th, 40K) in tissues and organs of various individuals of pumpkinseed Lepomisgibbosus (Linnaeus, 1758) from the Zaporizhzhia (Dnipro) reservoir. It has been revealed that in the bones of sexually mature pumpkinseed females, the content of radionuclides 137Cs and90Sr is 24.7% and 28.6% less, respectively, than in the bones of males. Summing up the materials of radioecological studies of 2017–2018, the following sequence of tissues and organs of the pumpkinseed by the ability to accumulate radionuclides was obtained: bone> muscle> scales> gills. Research results can be useful for further study on the fish radiation load in the basins of the Dnipro River and during monitoring radioecological research. It was determined that the content of radionuclides in the pumpkinseed muscles did not exceed the permissible levels of radionuclide content for fish as a food product (permissible levels of radionuclide content for 137Cs – 150 Bq/kg, 90Sr – 35 Bq/kg).

Integration of ecosystem science into radioecology: A consensus perspective

In the Fall of 2016 a workshop was held which brought together over 50 scientists from the ecological and radiological fields to discuss feasibility and challenges of reintegrating ecosystem science into radioecology. There is a growing desire to incorporate attributes of ecosystem science into radiological risk assessment and radioecological research more generally, fueled by recent advances in quantification of emergent ecosystem attributes and the desire to accurately reflect impacts of radiological stressors upon ecosystem function. This paper is a synthesis of the discussions and consensus of the workshop participant's responses to three primary questions, which were: 1) How can ecosystem science support radiological risk assessment? 2) What ecosystem level endpoints potentially could be used for radiological risk assessment? and 3) What inference strategies and associated methods would be most appropriate to assess the effects of radionuclides on ecosystem structure and function? The consensus of the participants was that ecosystem science can and should support radiological risk assessment through the incorporation of quantitative metrics that reflect ecosystem functions which are sensitive to radiological contaminants. The participants also agreed that many such endpoints exit or are thought to exit and while many are used in ecological risk assessment currently, additional data need to be collected that link the causal mechanisms of radiological exposure to these endpoints. Finally, the participants agreed that radiological risk assessments must be designed and informed by rigorous statistical frameworks capable of revealing the causal inference tying radiological exposure to the endpoints selected for measurement.

Practical radioecology support in the management and regulatory supervision of legacy sites

Legacy sites are a global issue. Experience has shown that every legacy site is different and case-specific management and remediation options have to be considered. Each site presents a unique mix of physical, chemical and radiological hazards and the significance of those hazards is likely to change over time. A life-cycle approach to remediation is therefore appropriate, with priority consideration allocated according to the major hazards, as technically determined by reference to policy on protection objectives and the corresponding regulatory requirements. Additionally, consideration will typically need to be given to wider issues as may be raised by stakeholders. The remediation approach also needs to take account of the waste management options on-site or involving off-site management and disposal. Radiological and wider environmental impact assessments are a crucial part of the holistic evaluation of hazards and risks (along with economic and societal impacts), which in turn underpin project planning, regulatory and wider decision making. This paper examines the role of radioecology in the assessment process, its contribution to reduction of scientific uncertainties in modelling ecosystem processes of release, transport and fate of radionuclides and evaluation of potential ensuing impacts on humans and the environment. Relevant examples are presented to illustrate the complexities of the processes in regulatory decision making, the various conditions that significantly affect the final solutions and how radioecology can be used in these situations. Whilst a case-specific approach will usually need to be taken to legacy sites, future remediation and clean-up work can be helpfully informed through sharing of experience from other sites. Continued international collaboration between all parties involved in legacy site management is therefore needed to inform on the development of practical regulatory guidance and to ensure that radioecological research is focussed on addressing the key issues that give rise to uncertainties that challenge regulatory and wider decision making.

Development of the optimal gamma-ray imaging system design

This article covers solutions in the field of the gamma-ray imaging systems, as well as proposes an optimal solution for design of such system.Gamma-ray imaging systems are proving their utility as a useful tool for radio-ecological research, investigation of isotope mishandling, nuclear incidents liquidation and so on. They allow viewing gamma-ray fields as if they were visible. For example, this kind of system is capable of pointing to radiation sources on top of video stream, which allows localization of radiation sources without the need of getting close to them with a dosimeter.Overview of the existing solutions covers directional imagers, collimator-based imagers, coded aperture imagers and rotation modulation systems. Each section of this paragraph outlines main advantages and disadvantages of the given solution.Based on a solution overview, a proposition of an optimal solution for this kind of system is made. Proposition covers a creation of the one-dimensional coded aperture system with modified uniformly-redundant array mask, scintillation detectors and FPGA-based data acquisition system. This kind of system uses a thick screen, also called mask, with holes. This screen casts a gamma-ray shadow onto an array of detectors. Then a data acquisition system is used to run a correlation algorithm, which finds a shadow pattern in detector’s readouts. This allows determining from what angle this shadow has been cast. The mask is formed by a modified uniformly-redundant array pattern to minimize the chance of incorrect correlation algorithm result and to use it’s ability to turn coded aperture into an inverse one. Performing measurements with and inverse mask allows compensation for irregular background radiation and irregularity between detector sensitivity in the array of sensors. It should also be noted, that using of such ability requires to physically turn the mask around it’s vertical axis.This paragraph outlines a number of design principles and requirements, such as avoidance of irregularities in radiation transparency of the mechanical construction, benefits of making the whole system remotely operated, overall requirements for supply and readout electronics and a proposal to use programmable logic integrated circuits as a data acquisition measure. This section also covers possible steps to improve system performance, via turning it around vertical axle, rotation of the viewing frame to create 2-dimensional images and performing correlation algorithm on the spectral data to distinguish different nuclides amongst gamma-ray sources.Overall conclusions of this article suggests an implementation of the test device to verify and field-test proposed technical solutions and to promote further research and development in this field.

Radioecological Research of Our Time: Socio-Psychological Aspects

Radioecology is a scientific discipline which studies how radioactive substances interact with nature; how different mechanisms affect the substances’ migration and uptake in food chain and ecosystems. Investigations in radioecology might include aspects of field sampling, designed field and laboratory experiments and the development of predictive simulation models. This multi- and interdisciplinary science combines techniques from some of the more basic, traditional fields, such as physics, chemistry, mathematics, biology, and ecology, with applied concepts in radiation protection. The main structural element of the system for ensuring radioecological safety of biocenoses and the population is radioecological activity in a number of areas: radioecological monitoring of territories, radiation survey of facilities, compilation of radiation and hygienic passports of territories, decontamination of identified foci of radioactive contamination, neutralization of radioactive waste, collection and removal of radioactive waste from the territory of the settlement people, maintenance in a safe state of the structures of the atomic industry laziness and facilities long-term (centuries-old) storage of radioactive waste, their accounting, forecasting the radiation situation in the controlled area, the development and implementation of measures for the prevention of accidents. At the levels of organizational and personal security, radioecological activity includes such areas: radioecological monitoring of territories and production capacities of organizations, radiation survey of organizational facilities, compilation of radiation and hygienic passports of their territories, decontamination of identified foci of radioactive contamination, personal hygiene and prevention of hidden, repeated exposures of employees / inhabitants of the contaminated region, neutralization of “leaks”, and removal of radioactive waste waste disposal from the territory of human settlements, radioecological competence / human culture and organization, strengthening of personal and organizational radioecological safety: formation of personality and organization of a “safe type”, that is, human skills and knowledge, production technologies and personnel management systems that avoid or correct dangerous and potentially dangerous actions of a person or a group, development and implementation of measures to prevent emergencies at the level of a person oh and organizational security and safety: the formation and strengthening of relations in the organization / community, allowing promptly correct or avoid errors that could lead to a dangerous emergency situations. The leading moment in this case is the upbringing and development of a safety culture, including the psychological safety of employees of nuclear industry enterprises.
