Radiation is one of the most effective methods of exposure in medicine. This method allows you to influence deeply located tissues without violating the integrity of the body. However, radiation has a destructive effect on the structures of the body, while the function of the organ is disrupted and its biomechanical properties change. The paper contains the results of various studies from 15 countries aimed at assessing the effects of radiation on the mechanical properties of human and animal body tissues. The studied papers contained information on the mechanical properties of skin, cornea, bone, tendons. Radiation doses in the range of 25-35 kGy are critical for various structures. However, large doses are needed to achieve maximum effect, while various chemicals and pharmacological preparations are used comprehensively to avoid irreversible changes in tissues. Thus, it is possible to preserve the structure and function of an organ or tissue while achieving the optimal effect of treatment. It is worth paying attention to the fact that radiation can have both positive and negative effects on biological tissues. Thus, the problem of assessing the effects of radiation on tissues and organs needs to be further studied due to the technical development and application of new medical technologies and devices.
