Safe radon levels - your complete guide for a healthy home 

Radon is a colorless, odorless, radioactive gas that resides in Group 19 of the Period Table. It forms naturally when uranium in soil, rock, and water breaks down.

Radon is the second leading cause of lung cancer after smoking, as noted by the Surgeon General. This risk is compounded over time, especially with prolonged exposure to high radon levels of this radioactive gas. Even at low levels, there's no zero risk, but the goal is to keep these levels as low as feasibly possible.

Here's the thing about radon: its levels can fluctuate based on various factors like changes in weather, seasons, and even day-to-day conditions. For example, radon levels tend to be higher during colder months when homes are sealed up. Contrarily, it's lower in warmer months when you keep the windows open. This variability is why one-time testing isn't enough. 

Besides, any modifications to your home can alter the radon levels. Renovations, changes in ventilation, or even installing a new heating system can impact how radon accumulates in your home. Therefore, continuous or periodic testing helps in tracking these changes, ensuring that the radon levels always remain in a safe range.

The radon test results provide levels of this radioactive gas in picocuries per liter (pCi/L). You can compare the numbers to the EPA's guidelines to determine the necessary course of action. 

Here’s a breakdown from safest to dangerous radon levels so you can better understand the test outcomes: 

• Safest Levels: Ideally, radon levels should be as low as possible. The U.S. Environmental Protection Agency (EPA) recommends taking action to reduce radon levels if they are 4 pCi/L or higher. But even levels below this can pose a risk. Your goal must be to maintain it around 2 pCi/L, which is generally considered safe.

• Moderate Levels (2 - 4 pCi/L): This range is a gray area. While not immediately alarming, it's higher than the ideal level. The EPA suggests considering remediation measures to reduce radon levels if they fall in this range. This implication gets more important if there are long-term occupancy plans for the building.

• Actionable Levels (4 pCi/L and Above): It is where the EPA strongly recommends taking action. Prolonged exposure to radon levels of 4 pCi/L or higher significantly increases the risk of lung cancer. You can employ radon mitigation systems to reduce these levels to a safer threshold.

When considering radon safety, every part of your building is significant. For instance, basements are known hotspots for radon due to their proximity to the ground. However, you can not overlook other areas like main living rooms, bedrooms, and even upper floors during testing. 

Radon, being a gas, has the ability to move freely through a building. This means that high radon levels in the basement can also translate to elevated levels elsewhere. Therefore, it’s crucial to take proper measures even though this house area usually remains uninhabited. 

The key to this is a comprehensive testing strategy. Testing different areas helps understand the spread and concentration of radon within a building. Moreover, this information is crucial for implementing effective mitigation strategies if needed. 

For instance, if only the basement shows high levels, the solution might be different compared to a situation where the living room has elevated radon levels.

Radon levels can vary significantly, not just from day to day but also across different seasons. Short-term radon tests, which last from 2 to 90 days, provide a quick snapshot of radon levels. However, they might not accurately reflect the average levels in your home throughout the year. 

On the other hand, long-term tests are more likely to give a comprehensive picture of your home's radon levels, taking into account these fluctuations. Such tests last for more than 90 days.

• Age of the House: As homes age, they undergo physical changes that can affect radon levels. For instance, new cracks can form in the foundation, walls, and floors, creating new pathways for radon to enter.

• Home Appliances and Ventilation: The use of home appliances like dryers, fireplaces, and ventilation fans can gradually alter radon levels in home. These appliances can affect the air pressure inside your home, potentially drawing more radon gas from the soil into your house.

• Seasonal and Environmental Factors: Seasonal changes, such as ground thawing or freezing, can also impact radon levels. The same goes for environmental factors, like barometric pressure changes.
  

Due to these fluctuations, continuous testing or periodic long-term testing is crucial. It's not uncommon for a house that initially tested low for radon to show higher levels later on.

Discovering high radon levels in your home can be concerning, but there's no need to panic. It's important to address the issue promptly and effectively to ensure the safety and health of your household. Here's a comprehensive guide on what you can do:

• Confirm the Problem: It's advised to conduct radon testing at least twice to ensure accuracy, as radon levels can fluctuate. Continuous monitoring is recommended for a more accurate assessment over time​.

• Hire a Professional: If high radon levels are confirmed, it's crucial to contact a licensed radon mitigation specialist. These professionals are trained to address radon problems effectively. Moreover, they also recommend the best course of action based on your home's specific situation​.

• Radon Reduction System: The most common method to reduce radon levels involves a vent pipe system and fan, known as a soil depressurization system. This system pulls radon from beneath the house and vents it outside. Sealing cracks and other openings in the foundation enhances the efficiency and cost-effectiveness of this system​​​.

• DIY Measures: While professional intervention is often necessary, there are steps you can take yourself. These include increasing airflow in your house by opening windows, using fans, and sealing cracks in floors and walls with suitable materials.

In our comprehensive article on safe radon levels, we've explored its origins and health implications along with crucial steps for monitoring and maintaining safe levels in home. Understanding the risks associated with radon and the importance of regular testing can't be understated, as it's key to ensuring a healthy living environment.
