В статье на основе анализа научной информации в отношении параметров проведения и характеристик полей излучения для 3 дентальных рентгенологических процедур (внутриротовые снимки, обзорные  снимки  на  ортопантомографах  и  конусно-лучевая  компьютерная  томография)  кратко описана методология и приведены примеры расчетов необходимой толщины стационарной защиты кабинетов с разным рентгеновским оборудованием. Показано, что в большинстве случаев в кабинетах, где выполняются внутриротовые снимки и обзорные снимки на ортопантомографах, обычные внутрикомнатные  перегородки  из  гипсокартона  толщиной  20  мм  обеспечивают  необходимую  за щиту для соблюдения в соседнем помещении предела дозы для населения. Для кабинетов, где проводятся  дентальные  исследования  с  применением  компьютерных  томографов,  необходима  дополнительная защита из свинца толщиной до 1,5 мм в зависимости от условий проведения и категории защищаемых лиц в соседнем помещении.

In the paper, based on the analysis of scientific information regarding the parameters and characteris-tics of radiation fields for three dental X-ray procedures (intraoral radiographs, panoramic radiographs on orthopantomographs and computed tomography), the required thickness of stationary shields for rooms with different X-ray equipment is calculated. It has been shown that in most cases, in rooms where intraoral and panoramic radiographs are taken, conventional 20 mm thick plasterboard interior room partitions provide the necessary protection to comply with the dose limit for the population in the adjacent room. For the rooms where dental examinations are carried out using computed tomographs additional lead shield up to 1.5 mm thick is required depending on the conditions and the category of protected persons in the adjacent room.
