Your Report, Explained.
Your Radon Report Card packs a lot of information into a single page. Here's a plain-English guide to every section, score, and recommendation so you know exactly what it means and what to do next.
What's on Your Report
Every report has five key parts. Here's what each one tells you.
Radon Report Card
This is your Home Safety GPA a single letter that combines all three risk categories using a weighted formula: Neighborhood (40%), Home Structure (30%), and Household (30%). Each grade maps to a specific recommended action, from a one-time lab test to connecting with a local professional.
Your risk is broken into three independent scores so you can see exactly where the concern is: your neighborhood's geology and test history, your home's structural characteristics, and your household's vulnerability profile. Each one is rated High, Moderate/Elevated, or Low.
Based on who lives in your home, you'll see specific callouts like why children's developing lungs face extra risk, why pets are more exposed near the floor, or how smoking multiplies radon's danger. These don't change your score; they make it personal.
If homes in your county have recorded radon levels greater than 10× the EPA action level, we flag it. This doesn't mean your home has those levels it means the ground beneath you is capable of producing them, and that's worth knowing.
Not a vague suggestion. Based on your grade, we recommend a specific action: a one-time lab test for peace of mind, a continuous radon monitor, or a connection to a certified local professional for a mitigation assessment.
What High, Moderate, and Low Actually Mean
Each of your three risk categories is scored independently. Here's what each level means and what we recommend.
What Each Grade Means
Your three pillar scores are combined into a single Home Safety GPA.
Your home sits in a low-risk zone with structural features that resist radon buildup. While your environment is healthy today, homes are dynamic.
Your current grade is stable, but your risk is variable. Specific factors suggest your levels may shift with the seasons.
Your home's profile indicates a significant safety gap. We're concerned about exposure spikes — peak levels that occur during specific weather patterns.
Your home has received a failing grade for air safety. Immediate diagnostic testing is required. We strongly recommend connecting with a local professional.
Everything You Need to Know
Discover the science, the safety, and the solutions behind our grading system.
Children breathe faster and take in more air relative to their size than adults. Because they have more years of life ahead of them, reducing their early exposure is one of the most impactful steps you can take for their long-term respiratory health.
Radon gas is heaviest near the floor exactly where your pets spend most of their time sleeping and playing. Since they can't tell us when the air feels "off," continuous monitoring ensures the environment is safe for the smallest members of your family.
When radon gas and tobacco smoke meet, the risk to your lungs isn't just added it's multiplied. If anyone in your home smokes, even moderate radon levels become a high priority.
Our lungs lose some of their natural resilience as we age, making environmental triggers more impactful. For those who spend most of their time at home, cumulative exposure adds up quickly. Monitoring ensures your home remains a truly healthy sanctuary.

No. Your Radon Report Card is a risk assessment, not a radon test. It tells you how likely your home is to have elevated radon based on your location, structure, and household and what kind of testing is appropriate. Only an actual radon test (lab kit or digital monitor) can tell you your pCi/L level.
You can but only after testing confirms your home has low radon levels. We reserve the "A" grade for homes with verified test results because no risk model, no matter how thorough, replaces an actual test. Once you test and confirm low levels, you earn the A.
Each of the three risk categories is scored independently, then combined using a weighted formula: Neighborhood Risk (40%) + Home Structure Risk (30%) + Household Risk (30%) = your Home Safety GPA. The GPA maps to a letter grade (B through F) with a specific recommended action. For full details, visit our data sources page.
Your Neighborhood Risk is fixed it's based on geology and location. But you can take action on your Home Structure and Household risks. For example, radon mitigation systems can address structural risk, and reducing smoking exposure directly lowers your Household Risk score. And of course, testing to confirm low levels earns you that "A."
EPA radon zone maps, CDC historical test results from local homes, NOAA climate normals, public property records for your home's structure, and a few simple questions you answer about your household. Everything is documented on ourdata sources page.
No. The callouts about children, pets, smoking, and elderly residents are informational they're designed to give you relevant context about why testing matters for your specific family. Your actual Household Risk score is calculated separately from the same underlying data.
