The article presents the analysis of a documentary array on Semipalatinsk nuclear test site using analytical services of the Web of Science database. It identifies the authors, organisations, countries, leading in the publications number at the research field. Shows the journals in which articles on the studied problem are published most frequently. Enumerates scientific meetings where the problems of Semipalatinsk test site were discussed and identifies the most cited publications. Using CiteSpace software, the paper reveals and visualises research fronts and its intellectual bases by means clustering and cluster automated labelling of Semipalatinsk test site papers co-citation network. Document co-citation network and research clusters are revealed using CiteSpace software. It shows, that studies are related to research of medical and biological (genetic changes, diseases as a result of ionizing radiation) effects of nuclear tests and its effects on the environmental situation (degree of contamination of the territory); the effectiveness of various dosimetry methods to determine the degree of radiation exposure on living organisms and objects of inanimate nature. The work represents scientometric visualisation of the documentary array showing research trends on Semipalatinsk nuclear test site.
