Abstract
<jats:p>The impact of the pathogenic factors that emerged as a result of the Chernobyl disaster on blood coagulation and hemostasis is of great interest. In the first years after exposure to ionizing radiation, detected deviations are primarily restorative and adaptive in nature. This article presents the results of monitoring changes in each separately studied indicator in the early (1987–1988) and late periods (2019–2020). The obtained regression equations describe the dynamics of changes in certain blood parameters, which make it possible to predict changes over many years after the accident. The hemoglobin and erythrocyte content, compared with the control group (donors), remained within the physiological norm until 1991. A significant decrease in the number of erythrocytes from 1991 to 1997, naturally, should have been reflected in the hemoglobin content, which was manifested by a decrease in their content. In the subsequent years of observations until 2001, a significant decrease in the number of erythrocytes corresponded to a decrease in the hemoglobin content. From 2001 to the present day, the content of erythrocytes and hemoglobin is approaching the boundaries of the physiological norm, albeit with some lag. Changes in blood indices are also influenced by factors that determine a liquidator's susceptibility to certain illnesses. Despite the fluctuating nature of changes in leukocytes, there is still a tendency to decrease. Stable moderate leukopenia has been observed since 1995. Rejuvenation of granulocytes is observed due to a decrease in the agranulocyte series of blood cells. Thus, it can be concluded that blood cells respond to the consequences of the Chernobyl accident even at late stages of observation.</jats:p>
