Given the increasing number of operational nuclear reactors worldwide, combined with the continued use of radioactive materials in both healthcare and industry, the unlikely occurrence of a civilian nuclear incident poses a small but real danger. This article provides an overview of the most important historical, medical, and scientific aspects associated with the most notable nuclear incidents to date. We have discussed fundamental principles of radiation monitoring, triage considerations, and the short- and long-term management of radiation exposure victims. The provision and maintenance of adequate radiation safety among first responders and emergency personnel are emphasized. Finally, an outline is included of decontamination, therapeutic, and prophylactic considerations pertaining to exposure to various radioactive materials.

Introduction: Civilian healthcare workers (HCW) and medical facilities are directly and indirectly impacted by armed conflict. In the Russia-Ukraine war, acute trauma care needs grew, the workforce was destabilised by HCW migrating or shifting roles to meet conflict needs, and facilities faced surge events. Chemical, biological, radiological, nuclear and explosive (CBRNE) exposure risks created unique preparedness needs.

Noble gas transport through geologic media has important applications in the prediction and characterization of measured gas signatures related to underground nuclear explosions (UNEs). Retarding processes such as adsorption can cause significant species fractionation of radionuclide gases, which has implications for measured and predicted signatures used to distinguish radioxenon originating from civilian nuclear facilities or from UNEs. Accounting for the effects of variable water saturation in geologic media on tracer transport is one of the most challenging aspects of modeling gas transport because there is no unifying relationship for the associated tortuosity changes between different rock types, and reactive transport processes such as adsorption that are affected by the presence of water likewise behave differently between gas species.

Objective: To assess the functional state and age-related characteristics of autophagy in peripheral blood leukocytes as a risk factor for the development of inflammaging using the example of the servicemen of the DefenseForces of Ukraine and clean-up workers of the Chornobyl accident.
Materials And Methods: A total of 103 male patients aged 28-77 (56,48 ∓ 9,05) years were examined. They included: the main group - 23 servicemen of the Defense Forces of Ukraine aged 44-59 (50,21 ∓ 5,13) years; the comparison group - 57 clean-up workers of the Chornobyl accident aged 56-63 (60,31 ∓ 1,78) years; and the control group -23 civilians aged 28-77 (53,26 ∓ 15,98) years.

With the development of science and technology, there is a great demand for electromagnetic wave absorbing materials for both military and civilian purposes. Among them, carbonyl iron powder (CIP) has attracted a lot of attention due to its mature production system and good electromagnetic wave loss capability. However, the application of CIP is limited due to poor impedance matching, poor corrosion resistance, and poor oxidation resistance.

Airborne gamma ray spectrum detection technology is an effective means to measure the concentration and spatial distribution of natural radionuclides in environmental media such as surface rocks and soil during aviation flight. Therefore, it is vital to fully explore the radiation information related to mineralization in airborne gamma spectrometry data and explore the dose distribution law of gamma radiation field of radionuclides in the detection area. This paper is based on the theoretical calculation model of ground-air interface gamma radiation field.
