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
Relevance: With a deep and extensive analysis of ionizing radiation levels characteristic of outer space and determining radiation hazard factors for astronauts, the issues of assessing the radiation situation in air travel also remain relevant.
Purpose: Was to assess the radiation doses of aircraft flight personnel over a year of professional activity and to justify measures to reduce them.
Material and methods: When calculating equivalent radiation doses during aviation flights, data from the RUSCOSMICS server was used, based on 90 hours of flights per calendar month with an annual flight time of 900 hours. The levels of the effective radiation dose of flight personnel during annual medical examinations for the purpose of medical flight examination are analyzed.
Results: It was found that the radiation dose of flight personnel amounted to 362 μSv for a calendar month, 3.62 mSv for 10 months of the year, which is higher than the average annual limit for the population, but does not exceed the sanitary standards for aircraft crews (5 mSv). The economic effect achieved by reducing the radiation dose to flight personnel from reducing the long-term effects of exposure determines the relevance and practical importance of improving measures to reduce the dose burden on aircraft flight personnel. A set of measures to reduce radiation doses to flight personnel should include: accounting for radiation doses to flight personnel during air travel and monitoring compliance with regulatory levels, reducing radiation doses to flight personnel during medical examinations, and reducing radiation doses to flight personnel by improving aircraft radiation protection.
Conclusion: The analysis of the total annual radiation doses to flight personnel during air travel in conditions of background solar activity and solar flares, as well as during medical diagnostic examinations, justifies the need for measures to reduce them in the main areas: accounting for radiation doses to flight personnel during air travel, monitoring compliance with regulatory levels, optimizing radiation diagnostic methods to exclude unjustified radiation exposure of flight personnel during medical examinations, as well as the development of promising design solutions to improve the anti-radiation protection of the aircraft cabin.
Keywords: aviation flights, flight personnel, professional exposure, medical examinations, radiation doses, radiation safety standards, radiation dose reduction
