Radon levels fluctuate due to seasonal variations, making a testing schedule crucial for safety. Protect your indoor air quality with expert radon testing for a healthier home. Radon, a colorless and odorless gas, poses serious risks, including lung cancer. The best time to test for radon is during winter when levels are typically higher.

Understanding radon exposure and implementing effective radon mitigation are both essential. MSE Environmental specializes in radon tests to identify and manage radon risks. Our team ensures comprehensive radon mitigation strategies and accurate testing throughout the year, providing peace of mind and a safer environment.

What is Radon and Why is it a Concern?

Radon Origin and Formation

Radon is a naturally occurring radioactive gas produced from the decay of uranium in soil, water, and rock. As uranium breaks down, it releases radon gas, which can accumulate in the surrounding soil. When radon escapes from the ground, it can enter buildings through various means:

• Cracks in the foundation

• Gaps around pipes

• Openings around sump pumps and drains

• Construction joints and other openings

Due to their design to retain heat or conditioned air, modern, airtight buildings are particularly susceptible to radon accumulation. This design can trap radon indoors, leading to higher concentrations.

Radon Exposure Health Risks

Radon exposure is a serious health concern due to its association with lung cancer and other health issues. Key risks include the following:

• After smoking, radon is the second leading cause of lung cancer.

• Prolonged inhalation of radon damages lung tissue and increases cancer risk.

• The risk of lung cancer is higher with increased radon levels and longer exposure durations.

Addressing radon in homes and workplaces is critical to preventing these health issues. Proper testing and mitigation can significantly reduce radon exposure and protect occupants from its harmful effects.

How Radon Levels Vary Seasonally

Radon Levels in Winter: Higher Risks

Closed Home Effect

Homes typically seal tightly during the winter months to conserve heat. This often leads to:

• Increased Radon Accumulation: With windows and doors closed, there is minimal air exchange between the indoors and outdoors. Due to reduced ventilation, radon gas, which naturally seeps into homes from the ground, can accumulate at higher levels.

• Limited Air Exchange: Without the influx of fresh air, radon concentrations inside the home can build up significantly, making it crucial to monitor radon levels during the colder months.

Stack Effect

The "stack effect" is a phenomenon where temperature differences between the inside and outside of a building create pressure differentials. This effect can cause:

• Warm Air Rise: In winter, warmer air inside the home rises and escapes through gaps and vents in the upper parts of the house.

• Radon Draw: As warm air escapes, it creates a vacuum effect that draws radon from the soil into the lower levels of the building. This draw potentially increases the radon concentrations in areas such as basements.

Frozen Ground

In colder climates, the ground around buildings can freeze, impacting radon levels by:

• Reducing Radon Escape: Frozen ground traps radon gas that escapes through soil pores, raising radon pressure and concentration near building foundations.

• Increased Radon Entry: Through foundation fractures and holes, radon from the soil enters the structure, raising indoor radon levels.

Spring and Fall: Fluctuating Radon Levels

Variable Temperatures and Ventilation

Spring and fall bring variable temperatures and changes in ventilation patterns, which can result in the following:

• Fluctuating Indoor Air Exchange: These transitional seasons often involve inconsistent heating or cooling and varying ventilation practices. Opening and closing windows and adjusting HVAC systems can lead to changes in indoor air exchange rates.

• Changing Radon Levels: These variations can cause radon levels to fluctuate as the balance between indoor and outdoor air pressure shifts. Variations make it challenging to predict and control radon concentrations.

Changing Soil Moisture

Seasonal changes in soil moisture due to weather patterns can influence radon levels:

• Increased Rainfall: During spring, increased rainfall and melting snow can raise soil moisture levels. This can impact how radon gas moves through the soil, potentially altering the rate at which radon enters buildings.

• Moisture Impact: Higher soil moisture may enhance soil permeability, allowing radon to migrate toward building foundations and affect indoor radon levels. 

Summer: Lower but Unpredictable Levels

Open Windows and Increased Ventilation

During the summer, people tend to open windows and doors more frequently, which generally helps to:

• Reduce Radon Accumulation: Enhanced ventilation allows radon gas to escape from inside the home and facilitates better air exchange, leading to lower indoor radon levels.

• Improve Air Exchange: Increased airflow helps to dilute and remove radon, reducing indoor radon concentration.

Air Conditioning Effects

While air conditioning can improve indoor comfort, it can also create conditions that affect radon levels:

• Negative Pressure: Air conditioning systems can create a negative pressure inside the home, especially when they are running frequently or intensively.

• Radon Draw: This negative pressure may inadvertently draw radon from the ground into the indoor environment, potentially raising radon levels inside the home.

Drier Soil Conditions

Summer often brings dry weather, which affects radon levels in a variety of ways:

• Soil Contraction: Prolonged dry conditions can cause soil to contract, creating gaps and cracks in the ground.

• New Pathways: These new pathways can allow radon to enter buildings more easily, leading to fluctuations and unpredictability in indoor radon levels.

Best Practices for Radon Testing

Short-Term Testing

Ideal Timing for Short-Term Tests

Short-term radon testing is a valuable method for quickly assessing radon levels. The following are the ideal conditions for conducting these tests:

• Winter is the Best Time: Winter is often the most suitable period for short-term radon testing. Homes typically seal throughout the winter, allowing for more accurate measurement of radon levels with less ventilation.

• Consistent Results: Testing during the winter months can help capture peak radon levels, making it easier to identify if radon levels exceed safe limits.

Long-Term Testing

Comprehensive Radon Measurement

We recommend long-term radon testing for a thorough understanding of radon exposure throughout the year. This approach offers several benefits:

• Year-Round Assessment: Long-term tests, which usually last 90 days to a year, provide a more comprehensive picture of radon levels throughout seasons and conditions.

• Accurate Measurement: By measuring radon levels over an extended period, these tests account for seasonal variations and fluctuations. This offers a more accurate representation of long-term radon exposure.

Retesting After Changes

Structural Modifications and Weather Events

Retesting for radon is crucial after significant changes to a home or its environment:

• Post-Renovation Testing: Major renovations, such as basement finishing or foundation work, can alter the building's radon pathways and airflow. It is essential to retest after such modifications to ensure radon levels remain within safe limits.

• Weather-Related Testing: Significant weather events, like flooding or heavy storms, can impact radon levels by altering soil conditions or affecting the building's foundation. Retesting after these events helps verify that radon levels have not been adversely affected.

Regular Testing Recommendations

EPA Guidelines

We recommend the following regular testing practices to maintain safe indoor air quality:

• Annual Testing: EPA suggests conducting radon tests at least once every two years, or more frequently if high radon levels were previously detected.

• Consistent Monitoring: Regular testing keeps indoor environments safe for occupants by quickly identifying and addressing any fluctuations in radon levels.
