The EPA Map of Radon Zones was created to help national, state, and local organizations:
• target resources
• support radon awareness efforts
• and implement radon-resistant building codes.

But the map was NOT designed to determine whether an individual home should be tested for radon.

Homes with elevated radon levels have been found in all three EPA zones.

That means:
high-risk counties can have low homes,
and low-risk counties can still have homes with elevated radon.

Every home is different.
Every home should be tested.

Quick question:

When was the last time you tested your home for radon?

Most people don’t realize it’s the leading cause of lung cancer in non-smokers—and it can be present in any home.

Drop a 👍 if you’ve tested
Drop a ❗ if you haven’t (no judgment—just a reminder)

What is the AARST Consortium on National Standards?

The AARST Consortium on National Standards is the formal standards-development body administered by AARST, a 501(c)(6) non-profit organization. The Consortium provides the structured, transparent forum where national consensus standards are created, reviewed, and maintained.

Through this program, diverse stakeholders—including radon and mitigation professionals, researchers, manufacturers, regulators, and public health experts—work together to develop ANSI-recognized standards that guide:

Radon measurement in existing buildings

Soil gas mitigation in existing buildings

Soil gas control and radon-resistant construction in new buildings

These standards are not theoretical. They are built on science, field experience, and ongoing public input, and they are routinely updated to reflect advances in technology, research, and best practices. This consensus-driven process is what gives ANSI/AARST standards their credibility and broad acceptance across the industry.

As part of supporting informed, professional practice, members of the Indoor Environments Association (IEA) receive **full access to all ANSI / AARST standards, including:

Fully searchable PDF files

Download and print privileges

Access beyond basic flipbook viewing

These standards form the foundation of quality, consistency, and public trust in radon and soil gas work nationwide.

Lung cancer isn’t just a smoker’s disease.

Radon is the leading cause of lung cancer among non-smokers—and most people don’t even know it’s in their homes.

The good news?
👉 It’s easy to test.
👉 It’s fixable.

Start with a certified professional through the National Radon Proficiency Program - NRPP.INFO

Because awareness is the first step—but action is what saves lives.

Iowa has taken an important step forward for healthier homes.

New legislation will require passive radon mitigation systems in newly constructed single-family and two-family homes across the state — bringing radon protection into the building process from the very beginning.

Prevention matters.
And healthier indoor environments start long before a family ever moves in.
