This review of the literature publications is focused on the articles in domestic and foreign editions devoted to the research on biological effects of electromagnetic radiation in the terahertz (THz) frequency range. It makes use of the Scopus, Web of Science, MedLine, RSCI, and other databases containing the relevant references for the period from 1970 up to the present days. This physical factor has found application in the Russian physiotherapeutic practice not very long ago. The main areas of its application include cardiovascular disease and neurological conditions. At the same time. the influence of electromagnetic radiation in the terahertz frequency range on human health and vital activity remains virtually unexplored. The available publications give evidence of the high biological activity of the terahertz electromagnetic waves which suggests the necessity of their further investigation.

The terahertz frequency range is promising for solving various practically important problems. However, for the terahertz technology development, there is still a problem with the lack of affordable and effective terahertz devices. One of the main tasks is to search for new materials with high sensitivity to terahertz radiation at room temperature. Bi1−xSbx thin films with various Sb concentrations seem to be suitable for such conditions. In this paper, the terahertz radiation influence onto the properties of thermoelectric Bi1−xSbx 200 nm films was investigated for the first time. The films were obtained by means of thermal evaporation in vacuum. They were affected by terahertz radiation at the frequency of 0.14 terahertz (THz) in the presence of thermal gradient, electric field or without these influences. The temporal dependencies of photoconductivity, temperature difference and voltage drop were measured. The obtained data demonstrate the possibility for practical use of Bi1−xSbx thin films for THz radiation detection. The results of our work promote the usage of these thermoelectric materials, as well as THz radiation detectors based on them, in various areas of modern THz photonics.
