“…In this work, we use the atmospheric transport model of the RODOS system of the European Union for nuclear emergency response [7]. It was recently implemented in Ukraine to predict the consequences of radiation accidents and analyze the risks associated with possible accidents [10,11].…”

“…When propagating at a distance of more than 10-20 km, it is necessary to take into account the influence of spatially and temporally variable meteorological conditions on the formation of pollution concentration fields, which is possible by using state-of-art atmospheric transport models (ATMs) that simulate cloud propagation based on data from numerical weather forecast models and are able to calculate atmospheric transport at distances from ~0.1 to ~1000 km. Examples of modern ATMs are the LASAT [5] and DIPCOT [6] models as part of the EU nuclear emergency response system RODOS [7], the WRF-CHEM and CMAQ Euler models [8], the FLEXPART Lagrangian model, and the CALPUFF Lagrangian-Eulerian model [9] and others. All of the above models are widely used in the world both for forecasting pollution in real-time and for analyzing environmental risks associated with possible emissions of pollutants into the atmosphere.…”

We studied the possibility of the combined application of screening models to assess the characteristics of sources in accidents at storage facilities for hazardous substances with complex models of atmospheric transport as part of modern decision support systems to calculate air pollution in a wide range of spatial and temporal scales. The evaporation time following an emergency spill, estimated by screening models, is used to set the emission intensity and calculate the atmospheric transport by the RODOS nuclear emergency response system. For the accident in Chernihiv on March 23, 2022, it was estimated that the maximum permissible concentration of ammonia 0.2 mg/m3 was exceeded at distances up to 75 km from the source. The dependence of the calculated maximum concentrations on time is close to asymptote cmax ~ t-4.5 up to 15 h after emission, which is consistent with the asymptote σ ~ t3/2 for the time dependence of the sizes of puffs following turbulent dispersion of instantaneous releases.

“…Designation of all these areas needs to be conducted based on a direct dosimetry analysis, based on active monitors used in situ. An alternative approach can be used based on the simulator real-time on-line decision support system (RODOS) application [28,29]. The simulator is dedicated to nuclear emergency management at national levels.…”

The current geopolitical situation and the war on Ukraine’s territory generate questions about the possible use of a nuclear weapon and create the need to refresh emergency protective plans for the population. Ensuring the protection of public health is a national responsibility, but the problem is of international size and global scale. Radiological or nuclear disasters need suitable decision making at the right time, which determine large effective radiation protection activities to ensure public health is protected, reduce fatalities, radiation disease, and other effects. In this study, a simulation of a single nuclear weapon detonation with an explosion yield of 0.3 and 1 Mt was applied for a hypothetical location, to indicate the required decision making and the need to trigger protocols for the protection of the population. The simulated explosion was located in a city center, in a European country, for the estimation of the size of the effects of the explosion and its consequences for public health. Based on the simulation results and knowledge obtained from historical nuclear events, practical suggestions, discussion, a review of the recommendations was conducted, exacerbated by the time constraints of a public health emergency. Making science-based decisions should encompass clear procedures with specific activities triggered immediately based on confirmed information, acquired from active or/and passive warning systems and radiometric specific analysis provided by authorized laboratories. This study has the potential to support the preparedness of decision makers in the event of a disaster or crisis-related emergency for population health management and summarizes the strengths and weaknesses of the current ability to respond.
