Confused About Radon

You’re not alone — especially if you’ve just taken a free radon test and received a radon number you don’t fully understand or disagree with.

• Maybe your result seems low, but someone is urging you to mitigate anyway.
• Maybe you’ve been given a bid over the phone without anyone inspecting your home.
• Maybe you’re looking at a proposal and can’t tell whether it’s reasonable, complete, or even necessary.

When you don’t know what your radon level means, what mitigation actually involves, or how to evaluate a contractor’s bid, it’s easy to feel pressured and unsure.

Radon Navigator™ is an independent, standards‑based guidance program that helps Utah families understand their radon results, evaluate mitigation needs, review contractor bids and more — all without cost, sales pressure, or obligation.

Understanding Your Radon Level

• Radon risk increases gradually, not suddenly
• The difference between 3.9 and 4.1 is small
• EPA’s action level is a guideline, not a danger line
• Retesting every two years is the national best practice

Why Families Need Our Guide

​Radon is a radioactive gas that can accumulate in any home. It’s invisible, odorless, and the leading cause of lung cancer in nonsmokers. More Utahns than ever are hearing that radon is dangerous, but they are not getting the information they actually need to protect their families, which includes:

• At what radon level mitigation is recommended
• How to select a qualified contractor
• What a fair price looks like
• What they’re agreeing to when they sign a mitigation contract
​
Unfortunately, most families end up learning these things from the very companies selling mitigation systems, a “fox guarding the hen house” scenario that leaves homeowners vulnerable to misinformation, shortcuts, and unfair practices.

The Radon Navigator™ Program is grounded in U.S. national radon soil gas measurement and mitigation standards established by the EPA and organizations that represent ethical, professional radon professionals — not the foreign or institutional frameworks many mitigators rely on.

​Our mission is to empower Utah families with standards‑based information, ethical support, and hands‑on advocacy through every step of radon testing and mitigation.

What We Do

Radon Navigator™ offers unbiased, standards-based information designed to help families understand important radon factors and make confident informed decisions about radon. 

QUICK FACTS ABOUT RADON

Questions	Answers
Are World Health Organization (WHO) Radon Standards the official radon guide for the United States?	No. In fact, the United States withdrew from WHO in January 2026.
What agency and standards are the official radon guide for the United States?	The Environmental Protection Agency (EPA) is the official agency, and the EPA has adopted soil gas measurement and mitigation standards created by the American National Standards Institute and American Association of Radon Scientists and Technologists (ANSI/AARST).
Do ANSI/AARST standards indicate radon levels as low as 2.7 pCi/L are highly dangerous and should be mitigated?	No. ANSI/AARST standards do not describe 2.7 pCi/L as ‘highly dangerous,’ nor do they require mitigation at that level. In the United States, the recognized action level remains 4.0 pCi/L. Homeowners may choose to mitigate at lower levels, but it is not required by ANSI/AARST.
Do the ANSI/AARST standards indicate creating a radon bid or plan while not physically inspecting the building to be mitigated is acceptable?	No. ANSI/AARST mitigation standards require on‑site diagnostics and a physical inspection of the building before a mitigation system can be designed or bid. Phone‑only, photo‑only, or flat‑rate bids do not meet the standards.
What is a reasonable price range for mitigation in Utah?	Most common range is $1,500 to $1,800 with more complex mitigations such as crawl space mitigation ranging $2,000 up to $3,500 or higher.
Can my Handyman or another nonradon professional legally install my mitigation system?	While Utah law only requires a handyman or any other nonradon professional to be a licensed contractor, best practice is that radon mitigation systems be designed and installed by an ANSI/AARST qualified, certified radon mitigation professional.
