STRUCTURE AND CHARACTERISTICS OF THE CHORNOBYL NPP ACCIDENT SURVIVORS REASONS OF DEATH ACCORDING TO THE MATERIALS OF MEDICAL EXPERTISE FOR THE CAUSAL RELATIONSHIP OF DISEASES WITH THE EFFECT OF IONIZING RADIATION IN THE REMOTE POSTACCIDENTAL PERIOD (2024 year).

Unlabelled: Problem of the causal relationship of disease that became the reason of death with the effect of ionizing radiation and due to harmful influence of the Chornobyl Catastrophe during performance of professional, military or official duties and / or living on radiation-contaminated areas, additional exposure not through their own fault but due to a radiation accident, caused the development of a special form of medical expertise as part of the of medical social protection system for suffered contingents in the remote postaccidental period.

Objective: To study and characterize the structure of the survivor categories (clean-up workers and victims) of the Chernobyl Catastrophe in the remote post-accident period (2013-2024) regarding the causal relationship of disease that became the reason of death with the effect of ionizing radiation and due to harmful influence of the Chornobyl Catastrophe based on the materials of expert cases of the Central Interdepartmental Expert Commission of the Ministry of Health of Ukraine (CIEC).

Material And Methods: The work was performed in the design of a retrospective study that based on analysis of the structure of all categories of Chornobyl NPP accident (ChNPP) survivors during 2008-2024 years and studying of 58,137 medical expert cases, including 19,524 postmortem cases, which were considered by CIEC during 2013-2023 to establish a causal relationship between the disease and influence of radiation exposure and other harmful factors and conditions during ChNPP accident.

STATE INSTITUTION «NATIONAL RESEARCH CENTER FOR RADIATION MEDICINE, HEMATOLOGY AND ONCOLOGY OF THE NATIONAL ACADEMY OF MEDICAL SCIENCES OF UKRAINE» - RESEARCH ACTIVITIES AND SCIENTIFIC ADVANCE IN 2023.

Research activities and scientific advance achieved in 2023 at the State Institution «National Research Center for Radiation Medicine of the National Academy of Medical Sciences of Ukraine» (NRCRM) concerning medical problems of the Chornobyl disaster, radiation medicine, radiobiology, radiation hygiene and epidemiology in collaboration with the WHO network of medical preparedness and assistance in radiation accidents are outlined in the annual report. The report presents the results of fundamental and applied research works of the study of radiation effects and health effects of the Chornobyl accident. The institution has been reorganized and since December 2023 has been called the State Institution «National Research Center for Radiation Medicine, Hematology and Oncology» (NRCRM).

Investigating the interaction of uranium(VI) with diatoms and their bacterial community: A microscopic and spectroscopic study.

Diatoms and bacteria play a vital role in investigating the ecological effects of heavy metals in the environment. Despite separate studies on metal interactions with diatoms and bacteria, there is a significant gap in research regarding heavy metal interactions within a diatom-bacterium system, which closely mirrors natural conditions. In this study, we aim to address this gap by examining the interaction of uranium(VI) (U(VI)) with Achnanthidium saprophilum freshwater diatoms and their natural bacterial community, primarily consisting of four successfully isolated bacterial strains (Acidovorax facilis, Agrobacterium fabrum, Brevundimonas mediterranea, and Pseudomonas peli) from the diatom culture.

No signs of microbial-influenced corrosion of cast iron and copper in bentonite microcosms after 400 days.

High-level radioactive waste needs to be safely stored for a long time in a deep geological repository by using a multi-barrier system. In this system, suitable barrier materials are selected that ideally show long-term stability to prevent early radionuclide release into the biosphere. In this study, different container matals (copper and cast iron) and pore water compositions (Opalinus Clay pore water and saline cap rock solution) were combined with Bavarian bentonite in static batch experiments to investigate microbial-influenced corrosion.

ACUTE RADIATION SICKNESS IN HUMAN: ETIOPATHOGENESIS, CLINIC, DIAGNOSIS AND TREATMENT (LECTURE).

Under the conditions of war in Ukraine, there remains a high probability that russia will use nuclear weapons or commit terrorist acts against nuclear power plants, which will lead to exposure of the population in doses that cause acute radiation sickness (ARS). In this regard, our medical service must be ready for the treatment of ARS of various degrees of severity under a mass influx of victims. In peacetime, ARS is a rather infrequent pathology, so most doctors lack experience in its treatment.
