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: A development of criteria and algorithm of chronic beryllium disease diagnosis using non-invasive laboratory techniques for the early detection of individuals predisposed to this pneumoconiosis.
Material and methods: Currently beryllium lymphocyte proliferation testing (BeLPT) is the main method for beryllium hypersensitivity status detection in screening of beryllium production workers in many countries. This technique is not widely used in Russia. In the present study flow cytometric BeLPT was used to measure lymphocyte proliferation in the groups of beryllium-exposed patients (main group — 24 persons) and beryllium-unexposed individuals (control group — 18 persons). Simultaneously we studied the beryllium effect on peripheral blood lymphocyte proliferation in PHA-stimulated cultures by differential staining of sister chromatids (fluorescence + Giemsa). This method allows to determine the content of first, second and subsequent mitosis in cultures. It has not been used for the determination of beryllium sensitization of people. The principal criterion for the selection of patients in the observation group was the documented fact of contact with beryllium compounds.
Results: Specific sensitization in beryllium-exposed patient by BeLPT was found for only one person. The use of the method of fluorescence + Giemsa revealed in both groups of persons a tendency to lymphocyte proliferation stimulation in cultures after BeSO4 addition up to 1 µM final concentration. However, the same level of lymphocyte proliferation was observed at higher concentrations of BeSO4 (10 and 100 µM) for beryllium-exposed patients. In contrast, the control group stimulating effect was held on.
Conclusions: 1. Up to now it is not possible to estimate reliably the informativity of BeLPT because the absence in Russia of the standard protocol for this method use and its results conventional interpretation. 2. It is necessary to increase the number of observations (number of persons in cohorts) to improve the reliability of the results obtained and more accurate interpretation of BeLPT effectiveness.
Key words: chronic beryllium disease, lymphocyte proliferation, Be-LPT test, fluorescent plus Giemsa method
