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: Experimental evaluation of the radioprotective effect of Erakond on spermatogenesis in BALB/c mice under external acute γ-irradiation.
Material and methods: Single external γ-irradiation of males at a dose of 1 Gy was carried out at the IGUR facility (137Cs, dose rate 0.85 Gy/min). Erakond was administered orally for 6 days followed by irradiation 2 weeks later. Violation of spermatogenesis and its correction by eracondas in irradiated animals was assessed by the morphofunctional state of the testes, spermatozoa and the reproductive function of males.
Results: In mice on days 16, 24, 48 after irradiation, the number of seminiferous tubules with destructive changes in the spermatogenic epithelium increases from 2.4 to 5.4; 10.2 8.3 % respectively. Erakond contributed to the reduction in the number of seminiferous tubules with destruction to 3.2; 5.1 and 3.5 % respectively.
On the 24th, 48th day after irradiation, the number of spermatozoa with an abnormal head increases from 2.8 to 4.8 and 4.5 %; and tail pathology from 4.2 to 8.2 and 7.5 %, respectively, the number of live spermatozoa decreases from 58.1 to 40.5 and 20.0 %, respectively. Erakond contributed to a decrease in the number of spermatozoa with an abnormal head to 3.0; 3.5 %, with tail pathology up to 6.1; 5.3 % and an increase in the number of live sperm up to 50.8; 35.5 % respectively.
In mice, on days 16, 24, and 48 after irradiation, the spermatogenea index decreased from 3.4 to 1.5; 0.9 and 2.1, respectively, Erakond contributed to an increase in the spermatogenesis index to 1.9; 2.1 and 2.9 respectively.
In mice after irradiation, pre-implantation death at the stages of mature spermatozoa, spermatids, spermatocytes and spermatogonia increased from 24.1 to 41.0; 39.8 and 44.7; 42.0 %, respectively, and post-implantation death at the stages of mature sperm, spermatids, spermatocytes from 16.9; up to 26.5; 27.1 and 38.4 % respectively. The number of live fetuses per female decreased from 5.8 to 3.0; 3.9 and 3.7 respectively. Erakond statistically significantly contributed to the reduction of pre-implantation death at the stages of mature sperm, spermatids, spermatocytes and spermatogonia to 35.6; 33.4; 37.5 and 34.1, respectively, and a decrease in post-implantation death at the stages of mature sperm, spermatids and spermatocytes to 21.6; 20.5 and 28.2 respectively.
Conclusion: The data obtained indicate the possible preventive use of Erakond as an effective dietary supplement for the correction of spermatogenesis disorders when exposed to ionizing radiation.
