In our daily life, we often come across the terms radiation and radioactivity. Although many people know that they are harmful to humans, they do not understand their true nature. However, ordinary objects around us, materials widely used in everyday life, can also contain radioactivity.

    Mohichehra Fayzullaeva, Master of Physics Faculty of Samarkand State University, is conducting a scientific study on the topic "Temporary change in the content of radioactive radon gas in residential buildings."

    - The radioactive gas isotope radon-222 is formed as a result of the decay of natural and artificial radioactive elements in the main building materials of houses in which residents live, - says researcher Mohichehra Fayzullaeva. - This isotope dissolves well in water and enters the human body through air and water and causes various pathological changes. For this reason, the study of the radioactive gas radon-222 is relevant today.

    The distribution of natural radioactive isotopes in different regions is not the same depending on the geographical location of the region. Radioactive isotopes enter the human body through the biological chain of air, water, consumer products and remain a source of internal radiation that irradiates the human body from the inside. The release of radionuclides into the body depends on the physicochemical properties of radionuclides, half-lives and accumulates in various organs of the body (bones, muscles, lungs, etc.) without complete removal. Exceeding a safe threshold for the amount of radioactive isotopes entering the human body leads to excessive exposure of people. Excessive radiation ionizes the atoms of healthy cells, destroys them, changes the composition of the blood, and can cause various life-threatening pathological processes (cancer, genetic diseases, infertility, skin and blood diseases). Therefore, the control of the amount, change and migration of radionuclides in environmental samples, the search for measures to reduce the accumulation of radionuclides are one of the urgent tasks facing the natural sciences in ensuring human radiation safety.
