Radon is a radioactive noble gas of natural origin, chemically inert, identified by the chemical symbol Rn and atomic number 86. It is formed by the decay of uranium and thorium, radioactive elements naturally occurring in the earth's crust. Being a gas, it can migrate through the soil and accumulate in enclosed spaces, such as homes, especially in areas with uranium-rich soils.
Main characteristics:
Colourless, odourless and tasteless, therefore impossible to detect without specific instruments.
It is considered a risk to human health, as inhaling radon and its decay products can increase the risk of lung cancer.
The University of Parma has conducted significant studies on radon, particularly with regard to its presence in drinking water in the province of Parma. These surveys were carried out by the university's Health Physics Service, analysing the radon content in groundwater and wells. The results showed variable radon concentrations, influenced by geochemical and physical factors.
