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: A number of researchers consider the study of the radioprotective properties of non-toxic or low-toxic natural substances to be a promising direction. A special place among them is occupied by antioxidants and participants in the basic reactions of metabolism. In order to avoid methodological errors when performing these studies, it is necessary to conduct a number of additional experiments. For example, in order to study the properties of various substances on cell cultures using tablet readers, it is first necessary to make sure that these substances do not affect the ability of cells to adsorb to the bottom of the wells of the tablet and do not interfere with cell proliferation. And if such an influence is detected, further experiments with these substances should be planned taking into account the information received.
Purpose: To search the effect of ascorbic, malic and succinic acids on the ability of lung adenocarcinoma cells (A549) to adhere in a 96-well plate, followed by the onset of proliferation by fluorescence registration method using Hoechst-33342 fluorophore.
Methodology: The experiment was carried out in a 96-well tablet. The working concentration of Hoechst-33342 was 1 μg/ml (1.62 μM). Fluorescence was recorded at a wavelength of 460 nm when the samples were excited by light with a wavelength of 355 nm. In an experiment to study the effect of ascorbate, malate and succinate on cell adhesion and proliferation, 20,000 cells and a solution of one of these substances in a working concentration of 2 mM were introduced into the cells of the tablet. The number of cells in the wells was estimated based on the fluorescence of Hoechst-33342 after a day of incubation.
Result: In samples containing 2 mM succinic acid and ascorbic acid, a statistically significant decrease in the intensity of fluorescence was observed compared with a sample that did not contain the drug. This suggests that these compounds negatively affect the growth properties of the A549 culture: they inhibit cell adhesion or slow down their proliferation.
Scope of the results and conclusions:The results obtained are necessary for the methodologically correct planning of the most detailed studies on the A549 cell line model using fluorescent methods, including studies on the radioprotective properties of ascorbate, malate and succinate under the influence of rare ionizing and neutron radiation.
Keywords: cell culture, A549, ascorbic acid, succinate, malic acid, Hoechst-33342 flatbed fluorimeter, influence estimation
