It publishes original research articles which cover questions of radiobiology, radiation medicine, radiation safety, radiation therapy, nuclear medicine and scientific reviews. In general the journal has more than 30 headings and it is of interest for specialists working in thefields of medicine¸ radiation biology, epidemiology, medical physics and technology. Since July 01, 2008 the journal has been published by State Research Center - Burnasyan Federal Medical Biophysical Center of Federal Medical Biological Agency. The founder from 1956 to the present time is the Ministry of Health of the Russian Federation, and from 2008 to the present time is the Federal Medical Biological Agency.
Members of the editorial board are scientists specializing in the field of radiation biology and medicine, radiation protection, radiation epidemiology, radiation oncology, radiation diagnostics and therapy, nuclear medicine and medical physics. The editorial board consists of academicians (members of the Russian Academy of Science (RAS)), the full member of Academy of Medical Sciences of the Republic of Armenia, corresponding members of the RAS, Doctors of Medicine, professor, candidates and doctors of biological, physical mathematics and engineering sciences. The editorial board is constantly replenished by experts who work in the CIS and foreign countries.
Six issues of the journal are published per year, the volume is 13.5 conventional printed sheets, 88 printer’s sheets, 1.000 copies. The journal has an identical full-text electronic version, which, simultaneously with the printed version and color drawings, is posted on the sites of the Scientific Electronic Library (SEL) and the journal's website.

The journal is included in the List of Russian Reviewed Scientific Journals of the Higher Attestation Commission. Since 2008 the journal has been available on the Internet and indexed in the RISC database which is placed on Web of Science. Since February 2nd, 2018, the journal "Medical Radiology and Radiation Safety" has been indexed in the SCOPUS abstract and citation database.
Brief electronic versions of the Journal have been publicly available since 2005 on the website of the Medical Radiology and Radiation Safety Journal: http://www.medradiol.ru. Since 2011, all issues of the journal as a whole are publicly available, and since 2016 - full-text versions of scientific articles. Since 2005, subscribers can purchase full versions of other articles of any issue only through the National Electronic Library. The editor of the Medical Radiology and Radiation Safety Journal in accordance with the National Electronic Library agreement has been providing the Library with all its production since 2005 until now.
The main working language of the journal is Russian, an additional language is English, which is used to write titles of articles, information about authors, annotations, key words, a list of literature.
Since 2017 the journal Medical Radiology and Radiation Safety has switched to digital identification of publications, assigning to each article the identifier of the digital object (DOI), which greatly accelerated the search for the location of the article on the Internet. In future it is planned to publish the English-language version of the journal Medical Radiology and Radiation Safety for its development. In order to obtain information about the publication activity of the journal in March 2015, a counter of readers' references to the materials posted on the site from 2005 to the present which is placed on the journal's website. During 2015 - 2016 years on average there were no more than 100-170 handlings per day. Publication of a number of articles, as well as electronic versions of profile monographs and collections in the public domain, dramatically increased the number of handlings to the journal's website to 500 - 800 per day, and the total number of visits to the site at the end of 2017 was more than 230.000.
The two-year impact factor of RISC, according to data for 2017, was 0.439, taking into account citation from all sources - 0.570, and the five-year impact factor of RISC - 0.352.

ABSTRACT
Purpose: To assess the demographic and magnetic resonance imaging (MRI) manifestations of aseptic necrosis and bone marrow infarction in patients before, during, and after the COVID-19 pandemic (2019–2023).
Material and methods: The study included 229 patients diagnosed with aseptic necrosis and bone marrow infarction using MRI between 2019 and 2023. The average age of the participants was 50±10 years. All patients underwent MRI using T2-weighted imaging (WI), T1-WI, PD-FS, T2-WI, and T1-WI with fat suppression. In patients diagnosed with aseptic osteonecrosis, the following MRI signs were recorded: marginal subcortical pathological MRI signal, narrowing of the joint space, joint effusion, bone marrow edema around the necrosis zone. For bone marrow infarction, the following signs were observed: a pathological MRI signal resembling a “geographic map,” heterogeneous increased signal on T2-WI and T1-WI, hyperintensity on STIR, and bone marrow edema around the periphery. Statistical analysis of the data was performed.
Results: The results of the study showed that aseptic necrosis of the joints developed more frequently in young, working-age individuals after the pandemic. An increase in the number of male patients with these pathologies was also noted. The incidence of aseptic necrosis increased by 10 % between 2019 and 2022, while bone marrow infarction increased by 3.5 % between 2019 and 2023. The number of bilateral joint lesions in 2019 was significantly lower (p<0.05) than in the post-COVID period, accounting for 8 % of the total number of patients with aseptic necrosis and bone marrow infarction. An increase in the prevalence of stages II and III of the disease was observed between 2019 and 2023.
Conclusion: The more frequent development of the disease in the most economically active population group (working-age men) with bilateral lesions necessitates the development of preventive measures and a comprehensive rehabilitation program, including potential prosthetic interventions. These measures aim to restore patients’ quality of life and enable them to continue their professional activities.
