What Is the Best Radon Mitigation System?

What Is Radon and Why Is It Dangerous?

Radon is a naturally occurring radioactive gas that forms from the decay of uranium in soil, rock, and water. It can seep into homes through cracks in the foundation, gaps around pipes, and even well water. Long-term exposure to radon is the second leading cause of lung cancer, making mitigation essential.

How Does Radon Enter Homes?

• Cracks in the foundation and basement floors
• Gaps around pipes, drains, and sump pumps
• Crawl spaces and poorly sealed walls
• Well water used for drinking and bathing

Types of Radon Mitigation Systems

1. Sub-Slab Depressurization (SSD) Systems – The most effective and widely used system. A vent pipe is installed under the foundation to draw radon gas out before it enters the home.
2. Drainage Systems – These systems help redirect radon-laden water away from the home, reducing overall radon levels.
3. Crawl Space Mitigation Techniques – Includes sealing crawl spaces with specialized vapor barriers and installing ventilation fans to prevent radon accumulation.
4. Passive Radon Mitigation Systems – Installed in new homes, these systems rely on natural airflow to reduce radon but may require an active fan if levels remain high.

Evaluating the Best Radon Mitigation Systems

Note, this information is by NRD Dealers' market line and homeowner preference through the years:

 

1. Sub-Slab Depressurization (SSD) Radon Mitigation Systems:

 

Rating: Highly Preferred.
Reasons:

• This is generally considered the most requested system, most commonly installed 
• It's applicable to a wide range of average American (United States of America) homes with slab-on-grade or basement foundations.
• When properly installed, it can significantly reduce radon levels.

2. Crawl Space Radon Mitigation Technique:

 

Rating: Situationally Preferred.
Reasons:

• Essential for homes with crawl spaces.
• Proper ealing and ventilation can effectively address radon entry and moisture from these areas.
• This method is very necessary when needing to address radon issues in homes with crawl spaces

3. Drainage Radon Mitigation System:

 

Rating: Less Common, Supplemental

Reasons:

• Primarily used when radon entry is associated with water intrusion.
• Often used in conjunction with other mitigation methods.
• Less often the sole mitigation method since effectiveness may vary depending on the specific drainage issues.

4. Passive Radon Mitigation System:

Rating: Varied, Often Upgraded
Reasons:

• Lower initial cost, as they rely on natural airflow
• Commonly installed in new construction or commercial structures
• Often needs to be upgraded to an active system

*Highlighted concerns:

• May not be effective in homes with high radon levels.
• Most of the time requires conversion to an active system for optimal performance
• Reliance on natural air flow, which is not always reliable

 

*NRD Dealers are always transparent with each client case and upholds integrity on which radon mitigation system advised to be installed. It's not always the case that if it would cost more, it would be more effective. It really points out on how it would work on your house type and radon levels. 

Choosing the Right Radon Mitigation/Remediation System

Always remember best is not best when it is not the correct one for you. Know these tips before going into the decision: 

• Efficiency: Look for radon mitigation companies who have a proven service line to reduce radon levels by 90% or more.
• Cost: Prices vary, with professional systems ranging from $1000 to $2,500 on a minimum, higher if depending on the structure to mitigate.
• Home Design Compatibility: Some systems work better in basements, while others are suited for crawl spaces. None of these not necessary means you cannot mitigate radon, there is always a solution for each home. 
• Professional Installation vs. DIY: Professional-installed systems are generally more effective and reliable.

Health Effects of Radon Exposure: Can Radon Make You Sick?

YES, 100%! Radon is never a myth, hoax, fraud, gimmick.. you name it. It has been discovered for a reason. While radon exposure primarily increases the risk of lung cancer, some people report symptoms such as:

• Persistent cough
• Headaches
• Fatigue
• Respiratory issues

Just now this early year, radon exposure has been linked to Leukemia, Asthma and even Gestational Diabetes!

What Radon Levels Are Considered Dangerous?

• EPA Recommended Action Level: 4.0 pCi/L or higher

- Who is EPA and how does it connect to radon? EPA stands for the Environmental Protection Agency, and it is primarily connected with radon because it is the government agency responsible for educating the public about the risks of radon exposure in homes and buildings, recommending action levels for radon mitigation, and conducting research on the issue; essentially making it the leading authority on radon in the United States. 

• WHO Radon Guidelines: 2.7 pCi/L or higher

- Who is WHO and how does it connect to radon? WHO stands for World Health Organization, and it connects with radon because the organization has classified radon as a known human carcinogen, meaning exposure to radon is linked to an increased risk of lung cancer, and they actively work to raise awareness about the dangers of radon exposure and encourage countries to take measures to reduce radon levels in homes and buildings globally; essentially, WHO considers radon a significant public health concern due to its potential to cause lung cancer. 

• Any Detectable Radon: While lower levels pose less risk, there is no completely "safe" level of radon exposure

There are a lot of organizations as well who relate to radon and it's negative impact to human health. That is the reason why awareness for prevention is always being highlighted to the public. Do not that there are no declared safe levels as yet! The best radon level is still zero/0. 

Professional Radon Testing and Mitigation Services: How to Choose a Radon Mitigation Contractor?

• Look for certified professionals with experience in radon reduction.
• Check customer reviews and ratings.
• Request multiple quotes to compare services and pricing.
• Ensure the system includes a fan and monitoring device to verify effectiveness.

The Importance of Regular Radon Testing

Even after mitigation, radon levels can fluctuate due to home modifications or seasonal changes. Radon levels has also been proven to be higher on the winter months or season. Regular testing ensures continued protection.

Less-to-No Cost Radon Reduction Strategies You Can Do

• Improve Ventilation: Increase airflow in basements and crawl spaces.
• Seal Cracks and Gaps: Prevent radon from seeping in through foundation cracks and wall openings.
• Use Radon Test Kits: Regularly monitor radon levels to ensure they remain low.

Limitations and Risks of DIY Radon Mitigation/Remediation Methods

You name it, radon remediation, radon abatement, radon reduction, radon mitigation... DIY mitigation can help but is often less effective than professional systems. No guarantee of making it work the first time either, so doubling the costs. Sealing cracks and increasing ventilation may lower radon levels, but they rarely eliminate the problem completely.

Protect Your Home and Health

Radon exposure is a serious health risk, but mitigation is both effective and accessible. Whether you're buying a home, already live in a high-radon area, or want peace of mind, investing in a radon mitigation system is one of the best decisions you can make. Take action today and schedule a radon test or consult a professional to assess your home’s radon levels. Your health—and your family’s—depends on it.
