Разработка электрохимических методов получения радионуклидных покрытий связана с рядом технологических и метрологических затруднений, обусловленных радиохимической спецификой процесса, такой как: применение истощаемых ультраразбавленных по металлу электролитов, особый контроль промывных вод, малый объем электролитических ванн вкупе с крайне высокой ценой изотопно обогащенного материала, необходимость получения специальных разрешений и лицензий. Предложен состав электролита, позволяющий ведение электрохимического осаждения никеля до полного истощения ванны по металлу, что не только позволяет точно контролировать количественные характеристики осадков, но и избегать образования жидких радиоактивных отходов. В работе также демонстрируется целесообразность определения, прямо или косвенно, на основе данных прямого радиометрического контроля ванн и покрытий таких параметров процесса, как полнота выработки электролита по целевому металлу, скорость падения концентрации металла в растворе, выход по току для реакции осаждения. Практический материал собран в процессе разработки комплексного щелочного электролита переменной концентрации для осаждения радиоактивных изотопов металлов группы железа.</p></abstract><trans-abstract xml:lang="en"><p>The present work highlights the distinctive features of the process of developing an electrolyte for radionuclide nickel plating. The development of electrochemical methods for producing radionuclide coatings is associated with a number of technological and metrological difficulties caused by the radiochemical specificity of the process, such as: the use of depletable electrolytes ultra-diluted in metal, special control of wash waters, a small volume of electrolytic baths coupled with an extremely high price of the isotopically enriched material, the need to obtain special permits and licenses. An electrolyte composition is proposed that allows electrochemical deposition of nickel until the bath is completely depleted in metal, which not only allows precise control over the quantitative characteristics of the deposits, but also avoids the formation of liquid radioactive waste. The paper also demonstrates the feasibility of determining, directly or indirectly, based on direct radiometric monitoring of baths and coatings, such process parameters as the completeness of electrolyte depletion by target metal, the rate of decrease in metal concentration in the solution, the current efficiency for the deposition reaction. Practical material was collected in the process of developing a complex alkaline depletable electrolyte for the precipitation of radioactive isotopes of iron group metals.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>никель</kwd><kwd>электроосаждение</kwd><kwd>радионуклид</kwd><kwd>никель-63</kwd><kwd>щелочной электролит</kwd></kwd-group><kwd-group xml:lang="en"><kwd>nickel</kwd><kwd>elecrtodeposition</kwd><kwd>radionuclide</kwd><kwd>nickel-63</kwd><kwd>alkaline electrolyte</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Ershova N.A., Krasnov A.A., Legotin S.A. et al.
