Представлены сведения об официально принятом диапазоне доз радиации (очень малые дозы — 0-0,01 Гр, малые дозы — 0,01-0,1 Гр, средние дозы — 0,1-1,0 Гр, большие дозы — свыше 1 Гр); обсуждается эволюция представлений об эффектах облучения на частоту болезней системы кровообращения: от больших и очень больших доз до декларации в последние годы возможного действия малых доз. Приведены положения из документов авторитетных организаций радиационного профиля (UNSCEAR, ICRP, NCRP, EPA и др.), согласно которым порог учащения смертности от болезней системы кровообращения составляет 0,5 Гр (диапазон средних доз), а эпидемиологические обоснования эффектов малых доз отсутствуют. Согласно подборке данных для шести стран, максимальные кумулятивные дозы от множественных CT по поводу диагностики COVID-19 меньше пороговой дозы на порядок, а средние кумулятивные дозы — на два порядка. Представлены также данные об отсутствии или исчезающе малом риске злокачественных новообразований после CT по указанному поводу.</p></abstract><trans-abstract xml:lang="en"><p>The review aim was to familiarize biomedical professionals with the latest evidence-based data on the effect of sparsely ionizing radiation (X-ray, γ- and β-radiation) on cardiovascular mortality (ICD-9: 390-459; ICD-10: I00-I99), which is especially important during the coronavirus disease 2019 (COVID-19) pandemic due to the increased use of computed tomography (CT) and X-ray procedures. Information is presented on the officially accepted range of radiation doses (very low doses — 0-0,01 Gy, low doses — 0,01-0,1 Gy, moderate doses — 0,1- 1,0 Gy, high doses — over 1 Gy). The evolution of ideas about the effects of radiation on the prevalence of cardiovascular diseases is discussed: from high and very high doses to the declaration in recent years of the possible effect of low doses. The statements from the documents of authoritative radiation organizations (UNSCEAR, ICRP, NCRP, EPA, etc.) are given, according to which the threshold for increasing cardiovascular mortality is 0,5 Gy (range of moderate doses), and there are no epidemiological justifications for the effects of low doses. According to a data for six countries, the maximum cumulative doses from multiple CT scans for COVID-19 diagnosis are one order less than the threshold dose, and the average cumulative doses are two orders less. Data on the absence or low risk of cancer after CT for this reason are also presented.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>болезни системы кровообращения</kwd><kwd>облучение</kwd><kwd>редкоионизирующая радиация</kwd><kwd>компьютерная томография</kwd><kwd>COVID-19</kwd></kwd-group><kwd-group xml:lang="en"><kwd>cardiovascular diseases</kwd><kwd>exposure</kwd><kwd>sparsely ionizing radiation</kwd><kwd>computed tomography</kwd><kwd>COVID-19</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Статья подготовлена в рамках бюджетной темы НИР ФМБА России и не поддерживалась никакими иными источниками финансирования</funding-statement><funding-statement xml:lang="en">The article was prepared within the budget theme of the research work of the Federal Medical-Biological Agency of Russia and was not supported by any other sources of funding</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Горизонтов П.Д., Мороз Б.Б.
