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.
Members of the editorial board are scientists specializing in the field of radiation biology and medicine, radiation protection, radiation epidemiology, radiation oncology, radiation diagnostics and therapy, nuclear medicine and medical physics. The editorial board consists of academicians (members of the Russian Academy of Science (RAS)), the full member of Academy of Medical Sciences of the Republic of Armenia, corresponding members of the RAS, Doctors of Medicine, professor, candidates and doctors of biological, physical mathematics and engineering sciences. The editorial board is constantly replenished by experts who work in the CIS and foreign countries.
Six issues of the journal are published per year, the volume is 13.5 conventional printed sheets, 88 printer’s sheets, 1.000 copies. The journal has an identical full-text electronic version, which, simultaneously with the printed version and color drawings, is posted on the sites of the Scientific Electronic Library (SEL) and the journal's website. The journal is distributed through the Rospechat Agency under the contract № 7407 of June 16, 2006, through individual buyers and commercial structures. The publication of articles is free.
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: Assessment of the impact of Pu-239 incorporation on Mayak workers lifetime based on the analysis of mortality and age in death at tumor and non-tumor diseases taking into consideration the main and secondary radionuclide deposition organs.
Material and methods: The cohort of Mayak workers hired from 1948 to 1958 with known Pu-239 body burden was included into the analysis. The cohort comprised 3478 individuals including 2414 men (1739 deceased and 675 alive) and 1064 women (604 deceased and 460 alive). Depending on Pu-239 incorporation the lifetime as integral characteristic of the increased and premature mortality was assessed based on the analysis of the mortality and age of death in tumor and non-tumor pathology of the main and secondary deposition organs. Statistical analysis was performed using STATISTICA software.
Results: It was found that with the increase of Pu-239 incorporation in the organism of the deceased workers a decrease of lifetime occurred by 5.2 years in men and by 6.6 years in women, and after starting work - by 6.9 years in men and by 7.7 years in women. In the whole cohort the decrease of lifetime was less expressed - by 4.2 years in men and by 2.7 years in women, and after starting work - by 6.2 and by 3.0 years correspondingly. We found the increase of levels of mortality from tumors in males, mainly from malignant neoplasms of the lung and liver, which are organs of Pu-239 main deposition. For the first time the associated with Pu-239 incorporation decrease of age at death (premature mortality) was found in case of tumor and non-tumor pathology of main and secondary deposition organs both for males and females. At that, unlike increased mortality, premature mortality was registered at all studied causes of death as a significant shift or tendency.
Conclusion: The conclusion was made that increased and premature mortality are two relatively different processes leading to the reduction of lifetime of professional workers exposed to the incorporation of Pu-239.
Key words: cohort of Mayak PA workers, Pu-239, organs of main and non-main deposition, tumor and non-tumor causes of death, age at death, employment age, lifetime
