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: The main purpose of the research is to define the group of radiation risk (GRR) on the incidence of hypertension among Russian recovery operation workers of the Chernobyl accident (liquidators).
Material and methods: The object of research is the cohort of the Russian liquidators with the known individual doses of external gamma exposure of all body. Definition of GRR on incidence of hypertension is based on assessment of excess relative radiation risk (ERR) and relative radiation risk (RR) in the observed cohort of 106 thousand liquidators, having average accumulated dose of external gamma exposure of all body of 0.11 Gy and the maximum individual doses about 1 Gy.
Results: From 1986 to 2012 in this cohort 57112 cases of hypertension have been diagnosed, basically - essential (primary) hypertension (39.2 %) and hypertensive heart disease (53.8 %). The statistically significant ERR of incidence of hypertension was observed only for liquidators who entered the Chernobyl zone of recovery operations within the first year after the accident (before 26.04.1987): ERR/Gy = 0.26 with 95 % CI (0.12; 0.41), p < 0.001. For other liquidators no significant associations between the explosion dose and the incidence of hypertension were revealed. For nonparametric estimates of RR in dose groups (relative to the control group with doses < 0.05 Gy) the statistically significant radiation risk was observed only for the dose group over 0,25 Gy: RR = 1.07 at 95 % of CI (1.02; 1.12), p = 0.023. GRR on incidence of hypertension equal to 4 % of the number of the studied cohort of liquidators: 4515 persons with accumulated doses of 0.25 Gy and higher, arrived to the Chernobyl area within the first year after the accident. In GRR 2597 cases of diseases of hypertension were diagnosed; statistically significant (p = 0.023) assessment of RR is equal 1.07, with 95 % a confidential interval (1.02; 1.12) and an average dose 0.297 Gy. During observation from 1986 to 2012 6.5 % of cases of diseases of hypertension (170 cases) in GRR can be related to radiation-caused ones. GRR for the beginning of 2013 consisted of 2919 persons 1909 of whom had already had diagnoses of hypertension (125 - radiation caused). Since 2013 for lifetime in GRR from 43 to 66 cases of diseases of hypertension which can be related to radiation-caused are expected.
Conclusion: As hypertension is the risk factor for many circulatory diseases, address prevention and treatment of hypertension in GRR in the first years after radiation accidents could reduce the radiation-caused loss healthy years of participants of elimination of such accidents.
Key words: radiation risk, radiation risk group, hypertension, liquidators, Chernobyl accident, excess relative risk (ERR), relative risk (RR), radiation doses
