Why Radon Testing Is the Only Way to Know

Radon is invisible and odorless. There are no physical symptoms or warning signs that indicate elevated levels in a home. Even homes that appear well-built, dry, and well-ventilated can have high radon levels.

Testing replaces assumptions with real data. It tells you:

Whether radon is present
How much radon is in the air
Whether action is recommended

Without testing, there is simply no reliable way to assess risk.

Types of Radon Tests

Radon tests fall into two main categories: short-term and long-term. Each serves a specific purpose depending on timing and goals.

Short-Term Radon Testing

Short-term tests typically measure radon levels over 48 to 96 hours. These are commonly used:

During real estate transactions
For initial screening
When quick results are needed

Short-term tests provide a snapshot of radon levels under controlled conditions.

Long-Term Radon Testing

Long-term tests measure radon over 90 days to one year. They provide a more accurate average because radon levels naturally fluctuate due to weather, seasons, and home use.

Long-term testing is ideal for:

Establishing a true annual average
Homes near action levels
Post-mitigation confirmation over time

How Professional Radon Testing Is Performed

Professional radon testing follows strict placement and environmental guidelines to ensure accuracy. Improper placement or conditions can lead to misleading results.

Professional testing includes:

Placement in the lowest livable level of the home
Avoiding drafts, windows, exterior walls, and HVAC vents
Maintaining closed-house conditions when required
Using calibrated, certified testing devices

At A+ Radon Solutions, we ensure testing is performed correctly so results reflect real indoor conditions, not testing errors.

Understanding Radon Test Results

Radon levels are measured in picocuries per liter (pCi/L). This number represents the concentration of radon gas in the air.

What the Numbers Mean

Below 2.0 pCi/L
Radon levels are considered low. No immediate action is needed, though periodic retesting is recommended.
Between 2.0 and 4.0 pCi/L
This range is considered moderate. While not required, many homeowners choose to mitigate, especially with long-term exposure.
4.0 pCi/L or higher
The EPA recommends taking action. Radon mitigation is strongly advised to reduce long-term health risk.

There is no completely “safe” level of radon, but risk increases as levels rise and exposure continues over time.

Why Radon Levels Can Vary

Radon test results are not static. Levels can change due to:

Weather and seasonal conditions
HVAC usage
Changes in home pressure
Renovations or foundation changes

This is why retesting is recommended every few years and after major home changes.

Why Professional Interpretation Matters

Seeing a number on a test result is only part of the picture. Understanding what that number means for your specific home is equally important.

Professional interpretation helps homeowners:

Understand whether results are typical or elevated
Determine if additional testing is needed
Decide whether mitigation is recommended
Avoid unnecessary worry or delays

At A+ Radon Solutions, we explain results clearly, answer questions, and provide guidance without pressure.

What Happens If Your Results Are High

If testing shows elevated radon levels, the next step is evaluation, not panic. Radon is a well-understood issue with a proven solution.

High results mean:

Radon is entering the home from below
Mitigation can effectively reduce levels
A properly designed system can provide long-term protection

Testing gives you the information needed to act confidently.

When to Test or Retest Your Home

Radon testing is recommended:

When purchasing or selling a home
Every two to five years
After installing a mitigation system
Following renovations or foundation work

Regular testing ensures continued peace of mind.
