Radon: What Are the Real Risks?
Radon is a naturally occurring, radioactive gas that can be found in homes and buildings all over the United States. It is produced by the breakdown of uranium in soil, rock, and water and can seep into homes through cracks in the foundation, flooring, or walls. Despite being odorless, tasteless, and invisible, radon is the second leading cause of lung cancer in the United States, second only to smoking. This is because when radon is present in the air, it can be inhaled, leading to the release of radioactive particles that can damage the cells in the lungs and potentially lead to cancer.
The Environmental Protection Agency (EPA) estimates that 21,000 lung cancer deaths each year are caused by radon exposure. In fact, the EPA states that “Radon is the leading cause of lung cancer among non-smokers, according to the American Lung Association.” This highlights the importance of testing for radon and taking steps to reduce exposure if elevated levels are found in a home.
Testing for radon is relatively simple and inexpensive. Professional testing companies may charge between $150 and $800 to complete a radon test. Short-term self-test kits, which take as little as two days to provide results, can be purchased for under $20. Long-term self tests for radon, which take more than 90 days to provide results, can also be purchased for around $40. The American Association of Radon Scientists and Technologists (AARST) recommends that all homes be tested for radon, regardless of location or type of construction.
If elevated levels of radon are found in a home, there are steps that can be taken to reduce exposure. The most common and effective method is to install a radon mitigation system, which can reduce radon levels by up to 99%. A mitigation system typically involves installing a pipe and fan system that ventilates radon gas from underneath the home to the outside. The cost of installing a radon mitigation system varies but usually ranges from $800 to $2,500.
It’s also important to know that running your heating or cooling system can actually increase your chances for elevated radon exposure. According to the National Radon Proficiency Program (NRPP), “Radon gas can be drawn into a home through the foundation, and when the home is sealed tight for energy efficiency, the radon gas can become trapped inside.” This means that by simply running your heating or cooling system, you are not only increasing the pressure inside your home, but also increasing the chance that radon gas will be drawn into the home.
In conclusion, radon is a serious health risk that can be found in homes and buildings all over the United States. It is the second leading cause of lung cancer in the United States, second only to smoking. Testing for radon is simple and inexpensive, and steps can be taken to reduce exposure if elevated levels are found. Remember that by simply running your heating or cooling system, you are increasing your chances for elevated radon exposure. It’s important to test your home for radon and take steps to reduce exposure if elevated levels are found.
