Описаны методы и средства воспроизведения и передачи единиц амбиентного и индивидуального эквивалентов дозы нейтронного излучения и их мощностей. Воспроизведение данных единиц величин осуществляется на основе восстановленного энергетического распределения нейтронов в диапазоне энергий 0,001–20 МэВ. Представлены требования к погрешности измерения единиц величин, в частности относительная расширенная неопределённость измерения поглощённой дозы и мощности поглощённой дозы нейтронного излучения не должна превышать 3 % при коэффициенте охвата, равном 2. Описаны состав и физические принципы работы ГЭТ 117-2023, который включает в себя новые технические средства: аппаратурно-методические комплексы воспроизведения, методы и средства измерений, установку поверочную нейтронного излучения с автоматизированной системой позиционирования источников нейтронного излучения УКПН-1МДА, систему наполнения камер газами. Представлены методы воспроизведения единиц величин и их функциональная зависимость. Приведены результаты исследований метрологических характеристик ГЭТ 117-2023. Метрологические характеристики ГЭТ 117-2023 соответствуют современным отечественным и международным стандартам по точности и диапазонам воспроизведения. Обеспечено единство измерений клинических дозиметров, необходимых для нейтронной лучевой терапии. ГЭТ 117-2023 играет ключевую роль в системе метрологического обеспечения дозиметрических измерений нейтронного излучения в таких областях, как здравоохранение, экология, атомная энергетика, промышленность, оборона и безопасность, наука, а также в ряде других сфер.</p></abstract><trans-abstract xml:lang="en"><p>The issues related to ensuring the uniformity of measurements and traceability of measurement results obtained using clinical dosimeters in neutron radiation therapy are considered in relation to the State Primary Standard of units of absorbed dose, absorbed dose rate, ambient and individual dose equivalents, ambient and individual dose equivalent rates of neutron radiation GET 117-2023. The methods and means of reproduction and transmission of units of ambient and individual equivalents of neutron radiation dose and their powers are described. Reproduction of these units of quantities is carried out on the basis of the reconstructed energy distribution of neutrons in the energy range of 0.001–20 MeV. Requirements for the measurement error of these units of quantities are presented, in particular, the relative expanded uncertainty of measuring the absorbed dose and the absorbed dose rate of neutron radiation should not exceed 3 % with a coverage factor of 2. The work describes the composition and physical principles of operation of the State Primary Standard. The standard includes new technical means: hardware and methodological complexes for reproduction, methods and means of measurement, a neutron radiation verification unit with an automated positioning system for neutron radiation sources UKPN-1MDA, a system for filling chambers with gases. The authors present a description of the methods for reproducing units of quantities and their functional dependence. The results of the study of the metrological characteristics of GET 117-2023 are presented. The metrological characteristics of the updated standard correspond to modern domestic and international standards for accuracy and reproduction ranges. The uniformity of measurements of clinical dosimeters required for neutron radiation therapy has been ensured. GET 117-2023 plays a key role in the system of metrological support for dosimetric measurements of neutron radiation in such areas as healthcare, ecology, nuclear energy, industry, defense and security, science, as well as in a number of other areas.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>эталон</kwd><kwd>поглощённая доза</kwd><kwd>амбиентный эквивалент дозы</kwd><kwd>индивидуальный эквивалент дозы</kwd><kwd>нейтронное излучение</kwd><kwd>дозиметрия</kwd><kwd>спектрометрия</kwd><kwd>метрологическое обеспечение</kwd><kwd>единство измерений</kwd><kwd>нейтронная лучевая терапия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>standard</kwd><kwd>absorbed dose</kwd><kwd>ambient dose equivalent</kwd><kwd>individual dose equivalent</kwd><kwd>neutron radiation</kwd><kwd>dosimetry</kwd><kwd>spectrometry</kwd><kwd>metrological assurance</kwd><kwd>uniformity of measurements</kwd><kwd>neutron radiation therapy</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Авторы выражают благодарность Корякину Сергею Николаевичу, Сабурову Вячеславу Олеговичу, Казакову Евгению Игоревичу из Отдела радиационной биофизики Медицинского радиологического научного центра имени А.
