The radon gas decomposes in turn into radon daughters which are radioactive metal atoms. They get stuck in our airways when inhaled. When this decay occurs, radiation is emitted from the radon daughters, which can damage the cells in our airways and lungs. In the worst case, they can cause cancer. The Swedish Radiation Safety Authority, SSM, estimates that 500 lung cancer cases per year are caused by radon in homes. The Riksdag has adopted two targets for radon. The radon content in schools and preschools must be lower than 200 Bq / m 3 by 2010, and the radon content in homes must be lower than 200 Bq / m 3 by 2020.
