С использованием заранее рассчитанных или измеренных функций отклика детектора на воздействие гамма-излучения заданной энергий и плотности потока определяется некоторая функция от энергии G(E). Используя эту функцию в качестве ядра интегрального преобразования от характеристики поля к дозе, можно получить величину дозы непосредственно из текущего аппаратурного спектра. Применяя функцию G(E) к энергетическому распределению флюенса фотонного излучения в окружающей среде, общая мощность дозы может быть определена без информации о распределении радиоизотопов в окружающей среде.</p><p>Для определения G(E) методом Монте-Карло рассчитываются аппаратурные функции отклика сцинтилляционного детектора на излучение моноэнергетических фотонных источников, а также другие характеристики. Далее весь энергетический диапазон регистрации разбивается на энергетические интервалы, для которых вычисляется функция G(E) с применением линейной интерполяции.</p><p>Рассматриваемый спектрометрический метод расчета дозы с применением функции G(E) позволяет использовать сцинтилляционные блоки детектирования для решения широкого круга дозиметрических задач. В статье приведен способ вычисления данной функции с помощью методов Монте-Карло и описываются особенности ее применения. Представлены результаты расчета функции G(E) для блока детектирования с NaI(Tl) детектором (Ø40 мм, h = 40 мм) и результаты его использования в качестве блока-компаратора для аттестации низкоинтенсивных полей фотонного излучения по мощности кермы в воздухе. </p></abstract><trans-abstract xml:lang="en"><p>Devices based on scintillation detector are highly sensitive to photon radiation and are widely used to measure the environment dose rate. Modernization of the measuring path to minimize the error in measuring the response of the detector to gamma radiation has already reached its technological ceiling and does not give the proper effect. More promising for this purpose are new methods of processing the obtained spectrometric information. The purpose of this work is the development of highly sensitive instruments based on scintillation detection units using a spectrometric method for calculating dose rate.</p><p>In this paper we consider the spectrometric method of dosimetry of gamma radiation based on the transformation of the measured instrumental spectrum. Using predetermined or measured functions of the detector response to the action of gamma radiation of a given energy and flux density, a certain function of the energy G(E) is determined. Using this function as the core of the integral transformation from the field to dose characteristic, it is possible to obtain the dose value directly from the current instrumentation spectrum. Applying the function G(E) to the energy distribution of the fluence of photon radiation in the environment, the total dose rate can be determined without information on the distribution of radioisotopes in the environment.</p><p>To determine G(E) by Monte-Carlo method instrumental response function of the scintillator detector to monoenergetic photon radiation sources as well as other characteristics are calculated. Then the whole full-scale energy range is divided into energy ranges for which the function G(E) is calculated using a linear interpolation.</p><p>Spectrometric method for dose calculation using the function G(E), which allows the use of scintillation detection units for a wide range of dosimetry applications is considered in the article. As well as describes the method of calculating this function by using Monte-Carlo methods and the features of its application. The results of the calculation function G(E) for the detection unit on the basis of NaI(Tl) detector (Ø40 mm, h = 40 mm) to use it as a comparator for kerma rate in the air certification of low intenseе photon radiation fields. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>сцинтилляционный детектор</kwd><kwd>оператор преобразования «спектр-доза»</kwd><kwd>метод Монте-Карло</kwd><kwd>компаратор</kwd></kwd-group><kwd-group xml:lang="en"><kwd>scintillation detector</kwd><kwd>spectrum-dose conversion operator</kwd><kwd>the Monte-Carlo method</kwd><kwd>comparator</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">Moriuchi, S.
