Radon danger in the Harz: Experts provide information about risks in Goslar!
In Goslar everything will soon revolve around a topic that often remains hidden: radon. An informative event on this topic will take place on September 25, 2025 from 7 p.m. to 8:30 p.m. in the Amsdorfhaus at Dorothea-Borchers-Straße 14. Organized by the Evangelical Adult Education Braunschweig, the event offers insights into regional radon occurrences and the associated health risks. Reason enough to bring this topic into the spotlight, because radon is not just any gas - it is a natural, radioactive noble gas that comes out of the ground and can accumulate in our buildings. regionalheute.de
The event is particularly relevant because elevated radon concentrations are considered a serious health risk. In fact, radon is thought to be responsible for a significant number of lung cancers. Scientific evidence shows that exposure to radon significantly increases the risk of dying from lung cancer. People who live in radon prevention areas, such as the cities of Goslar, Clausthal-Zellerfeld and Braunlage, are particularly at risk. These areas were created based on the monitored radon levels in order to take preventative action before the health-threatening effects become apparent. bfs.de
Expertise and content
Not only local experts but also well-known speakers will provide the necessary expertise during the information event: Dr. Friedhart Knolle, geologist at BUND, Dr. med. Claudio Knüsli, oncologist, and Roland Wolff, medical physicist. These experts will discuss how radon affects our lives and compare the handling of radon levels and limit values in Switzerland with the situation in Germany. In addition, preventative measures to reduce radon pollution are discussed, which can be relevant for every household.
Radon itself is colorless and odorless, but its short-lived decay products - including substances such as polonium and bismuth - release dangerous alpha radiation, which can particularly damage the respiratory tract. Interestingly, research studies show that the average indoor radon concentration in Germany is around 65 Bq/m³, while over 10% of the population reaches levels of over 100 Bq/m³. Around 0.25% even over 1000 Bq/m³. Caution is therefore advised: simple measures such as regular ventilation or sealing cellar doors can help minimize radon exposure. aerzteblatt.de
