**Reno Radon: New Builds Hiding Deadly Gas?**

Imagine walking into your new home in Reno, excited for a fresh start, only to discover an invisible threat lurking beneath the surface. It’s not a ghost, but something far more insidious: radon. This odorless, colorless gas, a byproduct of uranium decay in the soil, is a significant health hazard, especially in Nevada’s unique geological landscape. As a new homeowner in the Biggest Little City, understanding radon and taking proactive steps to mitigate it isn’t just a good idea; it’s a crucial responsibility.

Radon is a serious issue, and ignoring it won’t make it disappear. It’s the second leading cause of lung cancer in the United States, and Nevada, with its uranium-rich soil, has areas with elevated radon levels. This isn’t fear-mongering; it’s a call to action. Let’s dive into the specifics of radon in Reno, Nevada, and equip you with the knowledge to protect your home and family.

First, let’s understand Nevada’s radon landscape. The Nevada Radon Education Program, a valuable resource, highlights that certain areas, particularly in northern Nevada, are more prone to higher radon concentrations. This is due to the geological composition of the region, which includes granite and volcanic rock formations containing uranium. Reno, situated in Washoe County, falls within this higher-risk zone.

Nevada doesn’t have mandatory radon testing requirements for real estate transactions, unlike some other states. This means the onus is on you, the homeowner, to take the initiative. Don’t assume your home is safe just because it wasn’t tested during the sale.

DIY radon testing is a viable first step, especially in Reno’s high desert climate. The key is to choose a test kit specifically designed for short-term testing (2-7 days). These kits typically involve placing a passive collection device in the lowest livable area of your home, away from drafts and direct sunlight.

Here’s a step-by-step guide to DIY radon testing in Reno:

1. Purchase a Radon Test Kit: You can find these at local hardware stores like Lowe’s or Home Depot in Reno, or online. Make sure the kit is certified by the National Radon Proficiency Program (NRPP) or the National Radon Safety Board (NRSB).
2. Choose the Right Location: Place the test kit in the lowest livable level of your home. This is usually the basement, but if you don’t have a basement, choose the first floor. Avoid placing the kit in bathrooms, kitchens, or laundry rooms due to humidity.
3. Follow Instructions Carefully: Each kit comes with specific instructions. Read them thoroughly and follow them precisely. This includes recording the start and end dates and times of the test.
4. Seal the Room: Close windows and exterior doors for 12 hours before starting the test and keep them closed during the testing period. This helps to ensure an accurate reading.
5. Mail the Kit: After the testing period, seal the kit according to the instructions and mail it to the lab for analysis. The lab will provide you with a report of the radon levels in your home.

A common mistake is placing the test kit near windows or doors, which can skew the results. Another pitfall is not following the instructions precisely, leading to inaccurate readings. Pay close attention to the sealing instructions and the recommended testing period.

Interpreting your radon test results is crucial. The EPA recommends taking action if your radon level is 4 picocuries per liter (pCi/L) or higher. Even levels between 2 pCi/L and 4 pCi/L warrant consideration of mitigation.

It’s important to understand that radon levels can fluctuate. A single test provides a snapshot in time. For a more accurate assessment, consider conducting a long-term test (90 days or more).

If your DIY test reveals elevated radon levels, don’t panic. Professional radon mitigation is the next step. In Washoe County, several reputable radon mitigation companies can assess your home and install a system to reduce radon levels.

Here’s what to expect from a professional radon mitigation service in Reno:

1. Assessment: A qualified technician will inspect your home to identify potential entry points for radon. This includes cracks in the foundation, gaps around pipes, and sump pumps.
2. System Design: Based on the assessment, the technician will design a mitigation system tailored to your home’s specific needs. The most common method is sub-slab depressurization, which involves creating a vacuum beneath the concrete slab to draw radon gas away from the house.
3. Installation: The mitigation system typically involves installing a PVC pipe through the foundation and connecting it to a fan that vents the radon gas above the roofline. The system is designed to operate continuously and quietly.
4. Post-Mitigation Testing: After the system is installed, the technician will conduct another radon test to ensure the system is effectively reducing radon levels.

Navigating professional radon mitigation can be daunting. Get multiple quotes from licensed and insured contractors. Check their credentials with the Nevada State Contractors Board. Ask for references and review their past work.

A common challenge is choosing the right mitigation system. Sub-slab depressurization is generally the most effective method, but other options, such as sealing cracks and improving ventilation, may be appropriate in certain situations. Discuss the pros and cons of each option with your contractor.

Understanding local building codes related to radon-resistant construction is also important, especially if you’re considering new construction in areas like Damonte Ranch or Somersett. While Nevada doesn’t mandate radon-resistant construction statewide, some local jurisdictions may have specific requirements. Check with the City of Reno Building Department for the latest regulations.

Radon-resistant construction techniques include:

• Using a vapor barrier beneath the concrete slab.
• Installing a passive sub-slab depressurization system.
• Sealing cracks and openings in the foundation.
• Providing adequate ventilation in the basement or crawl space.

These measures can significantly reduce the risk of radon entering your home.

Don’t fall into the trap of thinking “it won’t happen to me.” Radon is a silent threat that can affect any home, regardless of age or location. Proactive testing and mitigation are essential for protecting your health and the health of your family.

Remember, knowledge is power. By understanding the risks of radon in Reno, Nevada, and taking the necessary steps to test and mitigate, you can create a safer and healthier home for yourself and your loved ones. Don’t delay; take action today. Your lungs will thank you.
