One of the problems in creating a radiation-hard scintillation composition on a polysiloxane base is the search for a radiation-hard activator capable of dissolving in such a base in sufficient quantity. In this work, in order to improve the solubility of p-terphenyl molecules in a polysiloxane base, its structure was modified with tert-butyl substituents. The obtained alkyl derivative of p-terphenyl was used as an activator of polysiloxane-based scintillators. The optical and scintillation properties of the obtained polysiloxane-based scintillators were studied, and their radiation hardness was determined.

Following the demands established by the current Ukrainian legislation, the Decommissioning Concept for the WWR-M research reactor was recently approved. The Concept envisages a strategy of immediate dismantling; it identifies and justifies the main technical and organizational measures for the preparation and implementation of decommissioning, the sequence of planned works and activities, as well as the necessary conditions and infrastructure. Decommissioning requires proper planning and demonstration that all planned dismantling works will be carried out safely. Presented safety assessment is a mandatory component of the Concept and the most important element of the overarching technological scheme. The purpose of the safety analysis is to provide input for detailed planning on how to ensure safety during decommissioning. Based on the results of the safety analysis, the measures to ensure radiation protection are defined while justifying their necessity and sufficiency.

The effect of preliminary irradiation of an aqueous solution of sodium chloride (saline) with 1 MeV high-energy electron beams on optical and cytotoxic/cytostatic properties of the dissolved Doxorubicin cancer drug is studied. With the use of Lewis lung carcinoma cell culture, it has been shown that the said treatment results in an increased cytotoxic/cytostatic action of the Doxorubicin, being the most pronounced in the range of low concentrations of the drug. The delivered dose of ionizing radiation on the saline ranged from 4 to 80 kGy. The maximum changes in the IR absorption spectra of Doxorubicin have been observed for the solutions irradiated with 10 kGy. The possible causes of the observed effects are discussed.

The reactor model was used to study the accident that destroyed the RBMK-1000 reactor at Unit 4 of the Chornobyl nuclear power plant on 26 April 1996. The model of reactivity accident of the RBMK-1000 reactor is based on equations of nuclear reactor kinetics, taking into account feedback in reactor reactivity. Reactivity changes as a result of both external influences – the movement of regulatory organs, changes in the reactor inlet coolant temperature, – and as a result of feedback by core parameters – changes in fuel temperature, coolant density, and 135Хе concentration. The model takes into account steam generation in the reactor core, which corresponds to the real physics of processes at the RBMK reactor, and allows obtaining simulation results that best match the recorded data and the consequences of the accident process. The study of reactivity accident on RBMK-1000 reactor is carried out for different combinations of values of control rods efficiency; reactivity coefficients by fuel temperature and coolant density; changes in the reactor inlet coolant temperature; the emergency protection time, as well as the reactor power level before closing the turbine generator stop valve. Different reactivity accident scenarios at RBMK-1000 reactor allow us to determine the most unfavorable combinations of external influences on the course of reactivity accident, namely: start time of main coolant pump rundown, time of activation of emergency protection, power level before the closing of turbine generator stop valves. In most reactivity accident scenarios, first of all, the critical values of fuel enthalpy are reached, at which the process of fuel destruction in the fuel element, destruction of the fuel assembly, and assembly channel start. Important results of studies are 1 – determination of the fact that time of activation of emergency protection after the closing of stop valves of turbine generator significantly affects the value of the maximum neutron power that is achieved during a reactivity accident; 2 – determination of the effect of reactor power before the closing of turbine generator stop valves on the course of the accident; 3 – it is not necessary to achieve supercritical on instantaneous neutrons, supercritical on delayed neutrons is enough to start fuel destruction.

The homo-transitional original and irradiated by electrons with E = 2 MeV; F = 5.9⋅1014 cm-2 ÷ 8.2⋅1016 cm-2 GaP LEDs were studied. The effect of radiation treatment on their electrical and optical characteristics was studied; the results of isochronous annealing of irradiated samples are given; the consequences of high-temperature annealing of output diodes are analyzed. Peculiarities of the formation of the current-voltage characteristics of red LEDs doped with Zn, O, and green LEDs doped with N under reverse bias, as well as features of the recovery of the reverse current during annealing of both types of LEDs, are revealed.

This article presents features of pre-Mesozoic Quaternary sediments and soil variations for the territory of the region. Middle-Upper Riphean sediments (sandstones) of the Lower Vendus (tuffs, basalts), represent the Polissia zone on the territory. The Lisostep zone is represented by Devonian sediments (interlayers of argillites, siltstones, and limestones). The soils of the Polissia area formed the mellow sand and moraine deposits and represent the soddy podzolic of the different levels of soil gleying. The soils of Lisostep formed less and loamy soils and they represent mainly grey forest podzolic and low humus chernozem with the marks of soil podzolization. The scale of quantitative and qualitative estimation of constrained ecological risk for the region population is set from lower to a high level with the value of radon current density out of the soil from 0 to 25 mBq/(m2⋅s), medium – from 25.1 to 50 mBq/(m2⋅s), higher than medium from 50.1 to 75 mBq/(m2⋅s), higher than 75 mBq/(m2⋅s). Notably, in the Polissia area, 46.3 % of the population suffers from a medium level of risk and in the area of Lisostep, 23.4 % of the population suffers from higher than medium risk and 4.6 % suffers from high-constrained ecological risk.

In this study, inelastic and elastic form factors for the low-lying excited states of 10B nucleus were calculated utilizing the nuclear shell model theory. We employed a large-basis psd model space with psdmwk interaction and the harmonic oscillator potential in the form factors calculation. The calculated results with the effective charge are in acceptable agreement with experimental results.

A radiological assessment of hayfields and pastures (Narodychy district, Zhytomyr region), which were taken out of economic use due to contamination after the Chornobyl accident, was performed. The possibility and ways of returning the lands to original use were considered. Maps of 137Cs and 90Sr soil contamination densities for the field were made and the corresponding statistical characteristics of the contamination were estimated. Estimates of 137Cs and 90Sr activity concentration in natural grasses, cow milk, and meat as well as the risks of exceeding by the values the permissible levels have been calculated. The possibility of using the land for the production of milk and meat has been shown in the example of the considered radioactively contaminated pastures.

The results of cytogenetic studies of bank voles (Myodes glareolus) carried out during 2009 - 2016 in the areas of the Chornobyl Exclusion Zone with different levels of radionuclide contamination are presented. In the remote period after the Chornobyl accident features of chromosomal instability in somatic cells of examined animals, manifested as elevated levels of bone marrow cells with micronuclei, are observed. Probably, they can be caused by transgenerational radiation-induced chromosomal instability and changes in the ecological characteristics of the population under the combined impact of chronic low-intensity radiation and negative environmental factors.
