ORGANIZATION OF RESEARCH AND COMPARATIVE ANALYSIS OF THE STRUCTURE OF ONCOLOGICAL DISEASES DURING THE COVID-19 PANDEMIC IN THE POPULATION LIVING IN THE CITIES OF INDUSTRIAL MINING OF URANIUM

Interest in the radiation effects of radon on the population arose at the beginning of the '80s of the XX century. Studies have shown that radon concentration in the air of residential buildings, especially single-story, often exceeds the permissible level set for uranium miners. Uranium also has no less harmful effects on the human body. The main dose a person receives in the premises where the city resident spends 80% of his time. The content of radon in the indoor air is determined by the specifics of the area's geological structure and the location on its territory of rock masses with high uranium content. The formation of very high radon activity indoors can lead to various natural and artificial factors, especially in areas of mineral development. The primary source of radon in the building is rocks and soils. Many houses in Kropyvnytskyi are built of building materials that include granite with high content of radon and uranium that negatively affects the health of residents of the city and region. Kropyvnytskyi is one of the three cities in Ukraine with the highest cancer mortality rate. One of the reasons is radon, a colorless, odorless, and tasteless gas. Radon is released from faults of the earth's crust and significantly affects the appearance of cancerous tumors.
