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.

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 analyze our own data on the dependence of neurological manifestations in liquidators of the Chernobyl accident on the dose within low values and observation time after irradiation.
Material and methods: The study was conducted with the participation of 141 liquidators of the consequences of a nuclear power plant accident. The analysis used clinical data on the nosology of neurological manifestations, which are presented in comparison with low radiation doses (31±6 and 190±22 mSv) and observation time after the accident (1986‒1988). The results are statistically substantiated.
Results: It was shown that there is no direct relationship between the incidence of neurological disorders and the dose of ionizing radiation within low values. On the contrary, a statistically significant predominance of their number was noted at lower doses – 31±6, relative to 190±22 mSv. The main phenomenology was reduced to neurocirculatory dystonia. The prevalence of vegetative-vascular dystonia and encephalopathy was almost the same during different periods of operation at the Chernobyl NPP and was always statistically significantly lower than the neurocirculatory dystonia. These data were correlated with the type of EEG activity.
Conclusion: The effects of low doses of ionizing radiation (31±6 and 190±22 mSv) during various periods of observation (1986‒1988) were characterized by a quantitative predominance of nosological forms in the form of neurocirculatory dystonia. Statistically significant, in a greater percentage of cases they were noted at lower doses (35.7 %, relatively, 18.7 % at higher doses). Analysis of observation periods of the effects of low doses confirms these data and represents the likelihood of their intensification in long-term observation periods:
1986 – 24.4 %, 1988 – 35.7 %, whereas at higher doses these changes were noted only in 1986 – 18.7 %.
