What causes radon poisoning?

Dr. Jeanne Morrison, PhD
Family Practitioner

Very small amounts of radon are commonly found in the environment because radon is formed by the natural breakdown of uranium, which is typically present in dirt and rocks. Radon is a gas, so it moves easily into the air, into buildings (through open doors or cracks in their foundations or basements), and through the soil. If it enters the groundwater, radon will be found in drinking water and well water. Radon poisoning is usually caused by breathing excessive amounts of radon for a prolonged period of time. This is most likely to occur in areas where the soil is rich in uranium, or when air circulation is not good, such as in mines or tightly sealed buildings with poor ventilation.
