Abstract: Dust storms are significant natural phenomena capable of transporting radionuclides and heavy metals over long distances. Dust storms are an important factor in the spread of radioactive substances in the environment. They are capable of transporting and accumulating radon and radium, which can subsequently create a potential threat to the environment. The results of ²²²Rn, 226Ra and...
