Radon Testing in Vancouver, WA
Radon cannot be seen or smelled. Testing the home is the way to learn its measured level.
Measure What the Senses Cannot Detect
Residential Radon Testing Based on the Home Itself
Maps and neighboring results cannot determine one property's level; a properly placed test provides property-specific measurement.
Radon is a naturally occurring radioactive gas that can enter buildings from the ground. It has no color or smell, so visual inspection cannot determine whether it is present at an elevated level. Residential radon testing uses appropriate measurement equipment and placement practices to gather results inside the home.
Clark County appears in EPA Radon Zone 1, the category associated with the highest predicted average screening potential. That designation is a reason to test, not a result for any individual property. Washington health guidance likewise emphasizes measurement because levels can differ between nearby homes and change over time.

Assumptions Testing Replaces
Why Radon Questions Need a Measurement
House age, foundation style, geography, and a neighbor's result cannot substitute for testing the property.
-
Radon Has No Visible Warning Sign
A home can look dry and well maintained while still requiring measurement to determine its indoor radon level.
-
Neighboring Homes Can Test Differently
Soil pathways, foundations, ventilation, and building operation vary enough that nearby results do not establish yours.
-
Home Age Does Not Predict a Result
New and old homes can both test at a range of levels; construction date alone is not a reliable screening method.
-
Test Conditions Affect Measurement
Device location, building conditions, movement, and other factors matter, so the provided instructions should be followed.
-
One Result Needs Proper Context
Results should be interpreted using current authoritative guidance, with additional testing or qualified consultation when appropriate.
Measurement in Four Stages
How Residential Radon Testing Works
The process centers on placement, stable test conditions, measurement, and a clear result.

-
Place the Testing Device
Appropriate equipment is positioned in a suitable area of the home according to the intended test method.
-
Maintain Test Conditions
Follow the provided building and device instructions so the measurement is not unnecessarily disturbed.
-
Review the Measured Result
Receive the property-specific result with clear context and direction to appropriate resources for any next step.
Radon in Southwest Washington
Local Context Without Property-Level Guessing
Regional designations support the decision to test, but only a measurement can describe the home during the test period.
Clark County Is EPA Zone 1
The county's predicted screening category supports testing, but it is not a substitute for an individual result.
The Instrument Supplies the Evidence
A measurement device—not sight, smell, home value, or neighborhood reputation—provides the relevant data.
Foundation Styles Differ
Slab, crawlspace, and basement configurations vary, but no foundation type rules out the need for testing.
Building Operation Can Matter
Ventilation and pressure conditions change, which is why test instructions and device placement are important.
Testing Is Not Mitigation
Pro-Inspection Services LLC provides the measurement service described here and does not imply mitigation work.
Use Current Health Guidance
EPA and Washington Department of Health resources provide the appropriate context for follow-up decisions.

Answers About Measuring Radon at Home
No. Radon is colorless and odorless. Testing the indoor air is the way to determine a home's measured level during the test period.
