Магнитно-резонансная томография (МРТ-графия) является одним из высокотехнологичных методов диагностики. Вместе с тем, специфические особенности электромагнитной обстановки и шумовых экспозиций на рабочих местах медицинского и технического персонала, осуществляющего эксплуатацию и обслуживание МРТ, изучены недостаточно и в настоящее время в РФ не учитываются при проведении гигиенической оценки условий труда.</p><p>Цель исследования - научное обоснование необходимости совершенствования гигиенической оценки электромагнитной и шумовой обстановки на рабочих местах персонала отделений МРТ.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Использован аналитический метод оценки действующих отечественных и зарубежных нормативно-методических документов, определяющих требования к гигиенической оценке электромагнитной обстановки и шума в отделениях МРТ. Выполнены более 4 тысяч измерений интенсивности электромагнитных полей и шума в 88 кабинетах г. Москвы, оборудованных разными типами МРТ (от 0,1 мТл до 3 Тл), и хронометражные исследования продолжительности их воздействия на персонал при выполнении различных видов работ. Проведены углубленные исследования амплитудно-временных и частотных параметров переменных ЭМП и звукового давления.</p></sec><sec><title>Результаты</title><p>Результаты. Критический анализ отечественных и зарубежных гигиенических нормативно-методических документов выявил существенные различия в контролируемых показателях, допустимых уровнях воздействия, методах контроля. Проведенные исследования показали, что медицинский и технический персонал отделений МРТ подвергается воздействию постоянных магнитных полей с высокими пространственными и временными градиентами и шума экстремальных уровней при проведении работ в непосредственной близости от магнита томографа. Особенностью электромагнитной обстановки является наличие переменных магнитных полей в широком диапазоне низких и радиочастот, имеющих сложную (импульсную) форму сигналов. Предложены новые ПДУ и нормируемые параметры МП низкочастотных диапазонов для их адекватной гигиенической оценки.</p></sec><sec><title>Заключение</title><p>Заключение.

Magnetic resonance imaging (MRI) is one of the most dynamically developing, high-tech diagnostic methods. At the same time, the specific features of the electromagnetic environment and noise exposures at the medical and technical personnel operating and maintaining MRI workplaces are not well understood and are currently not taken into account when conducting a hygienic assessment of working condition in the Russian Federation.</p><p>The aim of study is scientific substantiation of the need to improve the hygienic assessment of electromagnetic and noise conditions in the workplace of the staff of MRI departments.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. An analytical method to evaluate the current domestic and foreign regulatory and methodological documents that determine the hygienic assessment requirements for electromagnetic environment and noise in MRI departments was used. More than 4 thousand measurements of the intensity of electromagnetic fields and noise in 88 rooms in Moscow equipped with different types of MRI (from 0,1 mT to 3 T) and studies of the performing duration various types of work and electromagnetic field and noise exposure on personnel was done. The amplitude-time and frequency parameters of the variables of the electromagnetic field (EMF) and sound pressure detailed studies have been carried out.</p></sec><sec><title>Results</title><p>Results. Significant differences in controlled indicators, acceptable exposure levels, and control methods has revealed by critical analysis of domestic and foreign hygienic regulatory and methodological documents. The studies showed that the medical and technical personnel of MRI departments are exposed with high spatial and temporal gradients static magnetic fields and extreme levels of noise during diagnostic work in the immediate vicinity of the tomograph magnet. The presence of time-varying magnetic fields in a wide range of low frequencies and radio frequencies having a complicated (pulsed) waveform is a feature of the electromagnetic environment in MRI. New standardized control parameters and limit levels for low-frequency ranges magnetic fields for their adequate hygienic assessment are proposed.</p></sec><sec><title>Conclusion</title><p>Conclusion. The studies made it possible to substantiate the proposals the improving of electromagnetic field and noise hygienic assessment at the MRI staff workplaces.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>магнитно-резонансная томография</kwd><kwd>постоянные магнитные поля</kwd><kwd>электромагнитные поля</kwd><kwd>градиентные катушки</kwd><kwd>шум</kwd><kwd>спектральные характеристики</kwd><kwd>профессиональный риск</kwd><kwd>гигиенические регламенты</kwd></kwd-group><kwd-group xml:lang="en"><kwd>magnetic resonance imaging</kwd><kwd>static magnetic fields</kwd><kwd>electromagnetic fields</kwd><kwd>gradient coils</kwd><kwd>noise</kwd><kwd>spectral characteristics</kwd><kwd>occupational risk</kwd><kwd>hygiene regulations</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">McRobbie D.W.
