People still ask, “What is radon? ... Why should I be concerned about radon?"
Radon is a form of radiation that can build up in structures—homes, schools, and workplaces—coming from the decay products of uranium in the soil and rocks in the ground beneath the building.
Radioactive alpha particles are released into the air, can be breathed into our lungs, attached to cells in the lining of the lungs, change the DNA of those cells, develop into cancerous cells, and spread throughout our bodies.
