⏳ Deadline approaching: May 25, 2026

The public comment period for the ANSI/AARST MW-RN revisions (radon in water) is now open—but not for long.

This standard plays a critical role in how we:
✔️ Collect water samples
✔️ Handle and transfer them
✔️ Measure radon concentrations accurately

These updates help ensure consistency, reliability, and protection for occupants relying on groundwater sources.

If you work in radon, water testing, or environmental health—your input matters.

📌 Take a moment to review and submit your comments before the deadline.

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 radon professional through the National Radon Proficiency Program.

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

Well… this was unexpected. 😄

We added a fun radon awareness song to the beginning of our latest podcast episode…
and now we’re getting emails asking for it.

So here it is. 🎤

If it gets stuck in your head, don’t blame us—
just take it as your reminder to test your home.

Because radon might be invisible…
but ignoring it? That’s a risk we can actually do something about.

A big step forward for radon safety in new construction. (Standards.AARST.org)

At the recent code hearings in Orlando, the IRC-B committee approved the use of ANSI/AARST RRNC as an alternative compliance path within IRC Appendix BE.

Why does this matter?

Because this standard doesn’t just meet the minimum—it goes beyond it.
It gives builders and jurisdictions a stronger, more comprehensive option for radon control from the start.

This is what progress looks like:
✔️ Better guidance
✔️ More flexibility
✔️ Higher protection for occupants

Radon control isn’t a “nice to have.” It’s part of building smarter, healthier homes.

ANSI/AARST standards play a key role in supporting public health efforts related to radon.

Developed through a national consensus process, these standards help align professional practice with EPA radon guidance and long-term exposure reduction goals.

Most people think radon is only in the air.

But what if it’s coming from your water too?

For homes on private wells, radon in water can become a hidden pathway of exposure—especially during everyday activities like showering, laundry, and dishwashing.

And here’s the reality:
👉 You can’t assume it’s there…
👉 But you also can’t assume it’s not

You have to test.

Radon testing is an important step in understanding indoor air quality.

Accurate results depend on proper testing methods and qualified professionals.

We need to rethink what we know about lung cancer.

It’s no longer just a smoker’s disease.
1 in 5 cases are in non-smokers.

Radon exposure is a leading cause—and most people never test.

Don’t assume your home is safe.
Test. Verify. Act.
