Does Radon Cause Lung Cancer?

Radon gas is a naturally occurring radioactive substance released from rocks, soil, and groundwater. It has no smell, color, or taste, which makes it especially dangerous because you cannot detect it without proper testing. Health experts, including the Environmental Protection Agency (EPA), confirm that long-term radon exposure is directly linked to lung cancer, making it a serious indoor air quality concern.
​
This article answers the question, can radon gas cause lung cancer?, explains how the process works, and outlines steps you can take to protect yourself and your family.

Is Radon Really a Cause of Lung Cancer?

Yes. Radon gas is recognized as a leading cause of lung cancer in the United States, second only to smoking. According to the EPA, radon exposure contributes to approximately 21,000 lung cancer deaths each year.
​
When people inhale radon particles, they become lodged in the lungs, where they emit radiation that damages lung tissue over time. This cellular damage can eventually lead to cancerous growths. While symptoms may not appear immediately, years of exposure significantly increase the likelihood of developing lung cancer.

How Does Radon Gas Trigger Lung Cancer?

The harmful process starts with the radioactive particles released by radon. Once inhaled, these particles break down further, releasing alpha radiation inside the lungs. This radiation damages lung cells and DNA, and repeated exposure increases the risk of mutations that cause cancer.
​
One crucial fact: smokers exposed to radon face a much higher risk. Studies show that smoking combined with radon exposure increases lung cancer chances by up to ten times compared to non-smokers. However, even non-smokers remain at significant risk if they live in homes with elevated radon levels.

What Cancer Is Mostly Affected by Radon?

Radon gas primarily affects lung cancer, making it the most prominent type of cancer linked to radon exposure.

​The inhalation of radioactive particles released by radon can specifically impact the delicate lung tissue, leading to the formation of cancerous cells.

Recognizing the strong correlation between radon gas and lung cancer underscores the importance of taking preventive measures.

Testing for Radon Levels

Accurate testing for radon levels in your home is vital to assess potential risks and determine the necessary actions to reduce exposure.

Testing should be conducted in the following scenarios:

1. If your home has never been tested or if radon levels are unknown.
2. When preparing to buy or sell a home.
3. Before and after renovations, especially after repairing radon-related issues.
4. Before making significant lifestyle changes that involve spending more time in basements or lower levels.​

You can hire an expert to test for radon or do it yourself by obtaining a radon test kit at a hardware store. Contact your state's radon office for tools and information particular to your area.

Radon Reduction and Mitigation

Suppose your radon levels were four picocuries per liter (pCi/L) or higher. The EPA advises setting up a radon reduction system to reduce exposure, commonly called a radon mitigation system.

For the installation procedure, getting in touch with a certified expert is advised.

​Radon mitigation systems can effectively lower radon levels in your home, providing a safer living environment.

Additional Steps to Protect Yourself

In addition to reducing radon levels, you can take the following actions to protect your health:

1. Increase airflow in your home by utilizing fans and vents and regularly opening windows. However, note that natural ventilation is a temporary solution and insufficient to address radon concerns.
   
   
2. Seal any cracks in floors and walls using appropriate materials like plaster or caulk designed for this purpose.
   ​
3. Consult your state radon office for a list of qualified contractors who can assist in fixing radon problems. Always perform a follow-up test after mitigation to ensure effectiveness.

Final Thoughts

Radon gas poses a significant risk to our health, with lung cancer being the primary associated consequence. Radon can still be dangerous even though it ranks second to smoking as the primary cause of lung cancer in the non-smoking population.

​Testing your home for radon levels, employing mitigation systems when necessary, and taking additional steps to reduce exposure are essential for safeguarding yourself and your loved ones. 
​
By staying vigilant and informed, you can effectively protect against the potential dangers of radon gas and mitigate the risk of developing lung cancer.

Frequently Asked Questions (FAQs)

1. What is radon, and how does it impact our health? 

Radon is a natural radioactive gas from rocks, soil, and water. When inhaled, it can damage lung tissue and increase the risk of lung cancer development over time. Radon levels can vary in different regions, and testing your home for radon is crucial to assess potential risks.

2. Is radon the leading cause of lung cancer?

Radon is the second primary cause of lung cancer. Radon exposure dramatically increases the risk of developing lung cancer when paired with smoking.

​It is important to address radon levels in homes, especially for smokers or individuals who have quit smoking.

3. How can I test my home for radon?

A radon test can be performed by a professional, or you can purchase a radon test kit from a hardware shop and perform the test yourself.

​The process involves placing the kit in the lowest occupied level of your home for the recommended duration, usually a few days to a week. Once completed, you can send the kit to a laboratory for analysis.

4. What do radon levels in my home indicate?

The amount of radon in the air is expressed as the number of picocuries per liter (pCi/L). The EPA recommends action if your radon levels are measured at or above four pCi/L.

Lower levels still pose some risk, but mitigation measures become even more critical as the radon concentration increases. Regular testing and monitoring can help ensure your home remains within safe levels.

5. How can I reduce radon exposure in my home?

If the radon levels in your house are too high, a professional can install a radon reduction system, also called a radon mitigation system.

​These devices are designed to remove radon gas from the soil beneath your house. Taking preventative actions like improving ventilation, closing cracks in floors and walls, and enhancing airflow can also help lower radon levels in a home.
