Исходными данными для разработки и верификации модели служили результаты измерений характеристик поля гамма-излучения на рабочих местах дефектоскопистов и данные индивидуального дозиметрического контроля. Соотношения между измеряемыми (H*(10), Hp(10)) и нормируемыми (эффективная доза) величинами (коэффициенты перехода) определялись с помощью расчетов и фантомных экспериментов, моделирующих три основные операции полного производственного цикла работ: транспортировка дефектоскопа к месту просвечивания изделия, установка дефектоскопа для выполнения просвечивания и операция просвечивания изделия. В результате исследования было установлено, что более 90% дозового вклада в показания индивидуального дозиметра обусловлено установкой дефектоскопа в рабочее положение и просвечиванием изделия. Значения коэффициентов перехода для этих операций в виде отношения значений эффективной дозы и показаний дозиметров (Hp(10)), расположенных на теле работника на уровне груди (стандартное место) и уровне живота мало отличаются для обоих положений индивидуальных дозиметров. Использование максимального значения коэффициента перехода 0,8 Зв/Зв, соответствующего операции просвечивания изделия, будет обеспечивать консерватизм оценки эффективной дозы для всего производственного цикла не более чем на 15% и 25% для дозиметров, расположенных на уровне груди и живота, соответственно.</p></abstract><trans-abstract xml:lang="en"><p>A model of occupational exposure to gamma flaw detector operators working with portable flaw detectors in the field has been developed. The initial data for the development and verification of the model were the results of measurements of the characteristics of the gamma radiation field at the workplaces of flaw detectors and data from individual dosimetric monitoring. The relationships between the measured (H*(10), Hp(10)) and protection (effective dose) quantities (conversion coefficients) were determined using calculations and phantom experiments simulating three main operations of the full production cycle: transportation of the flaw detector to the place of X-raying of the product, installation of a flaw detector to perform x-raying and X-raying of the product. As a result of the study, it was found that more than 90% of the dose contribution to the readings of an individual dosimeter is due to the installation of the flaw detector in the working position and X-raying of the product. The values of the conversion coefficients for these operations in the form of the ratio of the effective dose values and the readings of dosimeters (Hp(10)) located on the worker's body at chest level (standard place) and abdominal level differ little for both positions of individual dosimeters. The use of maximum conversion coefficient value of 0.8 Sv/Sv corresponding to the operation of X-raying of the product will ensure conservatism in the assessment of the effective dose for the entire production cycle by no more than 15% and 25% for dosimeters located at the chest level and abdominal level, respectively.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>гамма-излучение</kwd><kwd>дефектоскопия</kwd><kwd>эффективная доза</kwd><kwd>индивидуальный эквивалент дозы</kwd></kwd-group><kwd-group xml:lang="en"><kwd>gamma radiation</kwd><kwd>flaw detection</kwd><kwd>effective dose</kwd><kwd>individual dose equivalent</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">BSS.
