Radon: Understanding and Protecting Your Health at Home
Radon, a radioactive gas, poses a significant health risk, especially when it comes to lung cancer. Despite being invisible, odorless, and tasteless, this harmful substance is present in every building and is second only to smoking as a leading cause of lung cancer. The Federal Office for Radiation Protection (BfS) based in Salzgitter, Lower Saxony, Germany, highlights the importance of personal measurements to accurately assess the risk of radon exposure in our homes.
The BfS recently released a nationwide radon map, displaying the average radon concentration in various cities and municipalities. While the national average is around 65 becquerels per cubic meter (Bq/m3), certain areas, such as low mountain ranges and mountainous regions, may have dangerously high concentrations exceeding 100 Bq/m3.
Inge Paulini, the BfS President, encourages everyone to take their own measurements, as there is no guaranteed safe threshold. Simple, affordable measuring devices can be ordered from specialized laboratories and set up easily. After the measurement period, the device is sent back to the laboratory for analysis, which usually costs between 30 and 50 euros.
To effectively assess the radon levels in your home, you can consider using a radon test kit or a digital radon detector. Short-term test kits, available for around $20, typically involve hanging a collector in the lowest habitable floor of your house for 2-7 days before sending it to a laboratory for analysis. Digital radon detectors, which provide continuous measurements and readouts, are commercially available as well.
If you are unsure about conducting the test yourself, hiring a licensed professional may be an option. The Environmental Protection Agency (EPA) recommends all houses be tested for radon. In Germany, the Bonn city area offers free radon measurements as part of a study conducted by the Federal Office for Radiation Protection (BfS). Professional testing costs vary, usually being more expensive than purchasing a test kit.

In the spirit of being thorough and going above and beyond, let's delve a bit deeper into the world of radon testing:
When it comes to conducting radon measurements, you have multiple options available to you:
- Purchase a Radon Test Kit: Short-term or long-term radon test kits can be purchased from various suppliers. Short-term kits, typically priced around $20, are used for initial screening purposes and require you to hang a collector in the lowest habitable floor of your house for 2-7 days before sending it off to a laboratory for analysis. Long-term kits, which collect data for up to a year, are also available.
- Use a Digital Radon Detector: Digital radon detectors provide ongoing measurements and can display daily, weekly, short-term, and long-term average readouts. These devices are commercially available and can be used for continuous monitoring.
- Professional Testing: If you prefer professional help, hiring a licensed home inspector can be an option. The EPA recommends all houses be tested for radon and offers guidelines on how to choose a radon professional.
In Germany, the Federal Office for Radon Protection (BfS) also offers free radon measurements in specific areas, such as Bonn. However, commercial test kits are widely available and cost around $20. Professional testing costs vary depending on the service provider and location.
So, whether you choose to take matters into your own hands or rely on professional assistance, the important thing is to be informed and proactive about the radon risks in your home. By acting now, you'll be able to protect yourself and your loved ones from potential harm.
