Результаты показали, что полученное экспериментальное значение мощности СВЧ 5 МВт является наиболее эффективным параметром для повышения качества ЭПР-спектров зубной эмали человека для диапазона аварийных доз облучения, даже с учетом разных типов спектрометров, на которых проводятся измерения. Оптимизация параметра регистрации спектров ЭПР, в частности мощность СВЧ, повышает качество полученных спектров для диапазона аварийных доз облучения, даже с учетом разных типов спектрометров, на которых проводятся измерения.</p></abstract><trans-abstract xml:lang="en"><p>It is known from the world literature that for EPR spectrometry for emergency dosimetry, where doses from 0.5 Gy and higher are used, the quality and reliability of calculating the experimental dose depends on the parameters of recording spectra (accumulation time, microwave power).</p><p>This article describes the results of the development and application of a method for optimizing the parameter of recording EPR spectra on human tooth enamel, such as microwave power, but in the range of emergency radiation doses (from 1 Gy to 5 Gy), under conditions of a local radiation incident based on a biodosimetric laboratory. The results showed that the obtained experimental microwave power value of 5 MW is the most effective parameter for improving the quality of EPR spectra of human tooth enamel for a range of emergency radiation doses, even taking into account different types of spectrometers on which measurements are carried out. Optimization of the parameter for recording EPR spectra, in particular microwave power, improves the quality of the obtained spectra for the range of emergency radiation doses, even taking into account different types of spectrometers on which measurements are carried out.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>ЭПР-дозиметрия</kwd><kwd>зубная эмаль</kwd><kwd>микроволновая мощность</kwd><kwd>физическая дозиметрия</kwd><kwd>ЭПР-спектр</kwd></kwd-group><kwd-group xml:lang="en"><kwd>EPR-dosimetry</kwd><kwd>tooth enamel</kwd><kwd>EPR microwave power</kwd><kwd>emergency human dosimetry</kwd><kwd>EPR spectra</kwd></kwd-group><funding-group xml:lang="en"><funding-statement>This research was funded by the Ministry of Energy of the Republic of Kazakhstan within the framework of the scientific and technical program “Nuclear power engineering development in the Republic of Kazakhstan” (IRN – BR24792713).</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">International Atomic Energy Agency (IAEA), Environmental Consequences of the Chernobyl Accident and Their Remediation: Twenty Years of Experience, IAEA Radiological Assessment Reports Series, 2006.</mixed-citation><mixed-citation xml:lang="en">International Atomic Energy Agency (IAEA), Environmental Consequences of the Chernobyl Accident and Their Remediation: Twenty Years of Experience, IAEA Radiological Assessment Reports Series, 2006.</mixed-citation></citation-alternatives></ref><ref id="cit2"><label>2</label><citation-alternatives><mixed-citation xml:lang="ru">International Atomic Energy Agency (IAEA), The Fukushima Daiichi Accident, 2015.</mixed-citation><mixed-citation xml:lang="en">International Atomic Energy Agency (IAEA), The Fukushima Daiichi Accident, 2015.</mixed-citation></citation-alternatives></ref><ref id="cit3"><label>3</label><citation-alternatives><mixed-citation xml:lang="ru">International Atomic Energy Agency (IAEA), The Radiological Accident in Chilca, 2018.</mixed-citation><mixed-citation xml:lang="en">International Atomic Energy Agency (IAEA), The Radiological Accident in Chilca, 2018.</mixed-citation></citation-alternatives></ref><ref id="cit4"><label>4</label><citation-alternatives><mixed-citation xml:lang="ru">TMT HANDBOOK, Triage, Monitoring and Treatment of People Exposed to Ionizing Radiation Following a Malevolent Act, 2009.</mixed-citation><mixed-citation xml:lang="en">TMT HANDBOOK, Triage, Monitoring and Treatment of People Exposed to Ionizing Radiation Following a Malevolent Act, 2009.</mixed-citation></citation-alternatives></ref><ref id="cit5"><label>5</label><citation-alternatives><mixed-citation xml:lang="ru">Romanyukha A. et al.
