WebbWhen you are exposed to radon many factors will determine whether you will be harmed. These factors include the dose (how much), the duration (how long), and how you come in contact with it. You must also consider any other chemicals you are exposed to and your age, sex, diet, family traits, lifestyle, and state of health. Top of Page WebbIn the outdoors, radon gas is diluted by fresh air, so it is not usually a concern. But radon can seep into buildings through dirt floors or cracks in the foundations. It may reach unsafe levels in enclosed, poorly ventilated spaces. Breathing in radon gas can damage cells that line the lungs. Radon exposure increases the risk for lung cancer.
WebbCRP137 indicates that for radon progeny of different particle sizes, the effective dose per unit exposure can vary by more than 8 times[1].At the same time, UNSCEAR's 2024 report pointed that in addition to respiration rate, radon progeny particle size distribution is the factor that has the greatest influence on radon exposure dose conversion coefficient[2].
