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 evaluate the efficiency of DNA repair in human peripheral blood lymphocytes irradiated ex vivo by 14.1 MeV neutrons.
Material and methods: The peripheral blood of three physically healthy male donors aged 28–40 years was used for the study. The peripheral blood was collected in K2EDTA vacutainers (Vacuette). All donors gave their consent to conduct this study. Isolation of lymphocytes was performed by centrifugation in a ficoll-verografin density gradient of 1.077 g/cm3 (Histopaque, Sigma-Aldrich) in accordance with the attached instructions. Cell irradiation was performed at the A.F. Tsyb Medical Radiological Research Center on the NG-14 neutron generator (FSUE VNIIA, Russia), which provided neutron fluxes with an energy of 14.1 MeV, and the gamma-therapeutic device “ROKUS-AM” (JSC Ravenstvo, Russia; cobalt-60, dose rate 0.5 Gy/min) at doses of 0.1, 0.25 and 0.5 Gy. To assess the effectiveness of DNA repair, the DNA comet method was used under alkaline conditions. The study was performed immediately after irradiation and after 15 min of cell incubation in complete culture medium at 37 °C. The tail moment and % DNA in the comet tail were used as a criterion for DNA damage. Statistical significance was assessed using analysis of variance (ANOVA).
Results: It was demonstrated that the efficiency of DNA repair in lymphocytes peripheral blood of a person after exposure to 14.1 MeV neutrons is ~ 4–5 times lower than after exposure to cobalt-60 gamma-radiation. The results obtained indicate that in the case of exposure to 14.1 MeV neutron radiation, the contribution of complex, difficult-to-repair DNA damage is much higher than when exposed to gamma radiation, which determines the high relative biological effectiveness of neutron radiation.
Keywords: fast neutrons, lymphocytes, DNA damage, DNA repair, DNA comet assay
