Radon Testing Does Not Have to Be Complicated

Radon cannot be seen, smelled, or tasted. It can accumulate in homes, multifamily properties, schools, commercial buildings, and other occupied spaces without producing any immediate warning signs.

The only way to know whether elevated radon is present is to test.

That part is straightforward. But for property owners, inspectors, housing authorities, and environmental professionals, arranging the testing can become more complicated than expected.

Which test device should you use? How many do you need? Where should they be placed? How long should the test run? What information must be documented? Where do the devices go afterward? And who can you call if something does not look right?

You do not need to become a radon laboratory expert to complete reliable testing.

Why Radon Testing Matters

Radon forms naturally as uranium in soil, rock, and water breaks down. The gas can move through the ground and enter a building through cracks, joints, utility penetrations, crawl spaces, and other openings.

Any building can have elevated radon. It does not matter whether the building is new or old, tightly sealed or drafty, or constructed with or without a basement. The radon level in one building also cannot reliably predict the level in a neighboring building.

According to the U.S. Environmental Protection Agency, radon is the leading cause of lung cancer among nonsmokers and the second-leading cause of lung cancer overall. The EPA estimates that radon exposure contributes to approximately 21,000 lung cancer deaths in the United States each year. Testing is the only way to determine the level of exposure.

For homes, the EPA recommends taking action to reduce radon when a test result is 4 picocuries per liter — or 4 pCi/L — or higher. The agency also recommends considering action when results fall between 2 and 4 pCi/L, because no level of radon exposure is considered completely risk-free.

A radon result is not simply another number in a report. It gives the property owner or project team the information needed to decide what should happen next.

The Test May Be Simple. The Process Still Matters.

A radon test device may be small, but the process surrounding it matters. Reliable radon testing depends on several connected steps:

1. 1Selecting the appropriate test method
2. 2Determining how many devices are needed
3. 3Placing the devices correctly
4. 4Maintaining the required testing conditions
5. 5Recording complete project and device information
6. 6Retrieving and returning the devices on time
7. 7Analyzing them through a qualified laboratory
8. 8Interpreting and acting on the results

A problem at any point can create questions about the final result. An improperly placed device, incomplete test information, disrupted testing conditions, or an unnecessary delay before laboratory analysis may make the result harder to interpret or use.

This is why choosing a radon laboratory should involve more than comparing a price on a list. You need a laboratory that understands the complete testing process and is available when questions arise.

You Do Not Need to Know Everything Before You Order

Some customers come to ETL knowing exactly what they need. They conduct radon testing regularly, understand the applicable protocols, and need a dependable source for test devices and laboratory analysis.

Others are completing their first radon project. They may know the approximate number of properties or locations involved but still have questions about the testing process.

Both are welcome at ETL. You do not need to understand every analytical method or arrive with a perfectly calculated order. Tell us what you are testing, approximately how many devices or locations are involved, and what you are trying to accomplish. We can help you understand the next step.

Radon Testing for Individual Properties

Testing a single home or property should be approachable. ETL makes it easier to obtain the necessary test devices, complete the test, and submit the devices for laboratory analysis.

Clear instructions help the person conducting the test understand:

• Where the device should be placed
• How long the testing period should last
• What conditions should be maintained
• What information must be recorded
• How the device should be returned
• What to expect from the laboratory result

If you encounter a question, you are not left trying to interpret the testing process by yourself. You can contact ETL and speak with someone who understands the device, the analysis, and the information the laboratory needs.

Radon Laboratory Support for Professionals

Inspectors, consultants, environmental firms, and other testing professionals need more than access to devices. They need a laboratory relationship that supports repeatable work — dependable analytical capacity, consistent reporting, clear submission procedures, and access to knowledgeable people when something unusual occurs.

• ✓Radon test devices
• ✓Certified laboratory analysis
• ✓Order quantities for projects of different sizes
• ✓Clear device-handling and submission instructions
• ✓Responsive assistance with project or sample questions
• ✓Consistent reporting that can be incorporated into project files

ETL is listed by the National Radon Proficiency Program as an approved radon laboratory for BREEZE liquid scintillation devices.

That laboratory capability is paired with something equally important: accessibility. If a device arrives with incomplete information, a testing condition needs clarification, or a project suddenly changes, you can talk to a person who understands the work.

Support for Multifamily and High-Volume Projects

Radon testing becomes more logistically demanding when the project includes multiple units, buildings, or properties. The challenge is no longer limited to placing one device correctly — the project team must coordinate device quantities, locations, identification, deployment, retrieval, documentation, shipping, analysis, and reporting across the entire program.

Small inconsistencies can become large problems when repeated across dozens or hundreds of devices.

ETL supports larger projects with volume ordering options, laboratory capacity, and direct communication throughout the process. Whether you are planning a single multifamily assessment or an ongoing testing program, we can help you work through questions such as:

• Approximately how many devices will be required?
• How should devices and locations be identified?
• What information must accompany each device?
• How should a larger batch be packaged and returned?
• How can results be kept organized across multiple properties?
• What happens if some devices require additional attention?

The goal is not to leave the property manager or environmental professional managing the laboratory process alone. The goal is to make radon analysis one coordinated part of the larger project.

Why Work With ETL?

There are many places to purchase a radon test. ETL is built for customers who want more than a device arriving in the mail.

Radon does not always exist as an isolated project need. ETL is part of a broader environmental testing organization with experience supporting consultants, contractors, property managers, housing authorities, and other environmental professionals.

What Happens After You Receive the Result?

A radon laboratory result reports the measured radon concentration, typically in picocuries per liter. For residential properties, the EPA recommends taking action when the result is 4 pCi/L or higher and considering action when the result falls between 2 and 4 pCi/L.

The correct next step may depend on:

• The reported concentration
• The type and duration of the test
• The property and its occupancy
• Applicable regulatory or program requirements
• Whether follow-up or confirmation testing is appropriate
• Whether a radon mitigation system is already present
• Whether the test is being used for a transaction, housing program, or compliance purpose

ETL provides the analytical result. When additional professional evaluation, follow-up testing, or mitigation is needed, the result becomes the starting point for that next decision.
