Radon Safety LLC Offers Free Post Mitigation Testing by Airchek

The Most Widely Used Independent Lab Radon Testing Method in the World.

What Do Home Radon Tests Measure?

Radon tests measure the quantity of radiation in a specified volume of air in the units of “picocuries per liter.”  This is abbreviated as “pCi/L”


How Do You Interpret Radon Test Results?

EPA Recommends 4.0 pCi/L as “action level.” Above this level, the EPA suggests you take corrective measures to reduce exposure to Radon. There is a lot more information on this on our “How Risky is Radon Page


How Long Do Radon Tests Take?

The shortest period that can be tested is 48 hours. This is true of all testing methods. If you’re using a Passive Radon Test then it would need to be sent to the lab and at least one day for analysis..so about 4 days if you overnight the kit to the lab. If you hire a professional with a Continuous Monitor then it would be 48 hours and they can usually provide results when they end the test and pick up the device.


Radon Testing Cost

Passive Testing Devices typically cost  $15 to $100
Active Testing Devices set by Impartial Home Inspector typically cost $100 to $250.

Who Should Perform the Radon Inspection or Test?

“Be aware that a potential conflict of interest exists if the same person or firm performs the testing and installs the mitigation system. “

***From the US EPA’s Home Buyer and Seller’s Guide to Radon*** 


  • The Testing Device Should be Handled by You or A Neutral Third Party… Not by the Mitigation Company

    We believe that you should either set and mail a test kit yourself or have a home inspector who is NOT affiliated or paid by a radon mitigation company perform the test.

Why We Feel this Way:

There have been proven instances in Colorado of tests being manipulated by Radon Contractors The stories are outrageous. The details are basically too incendiary to publish here but the Colorado Dept of Health knows about all kinds of these situations. That’s why they say: “When it comes to Radon in Colorado…it’s ‘let the buyer beware.”

Though we could probably make a lot of money by performing radon tests [& getting the subsequent mitigation work]…we at Radon Safety LLC strongly believe that it’s a conflict of interest for us to perform radon testing, so we do not actually ever handle any testing devices. [All our post mitigation testing is included in the price and done through Airchek.]

  • Or Handled by a Radon Testing Home Inspector Or Handled by a Radon Testing Home Inspector

    If the customer wants a test done with a Continuous Radon Monitor device we STRONGLY recommend using a Home Inspector who is not affiliated with a Radon Mitigation Company and who does not receive a commission for steering jobs to a particular radon mitigation contractor. [See below for suggestions]

Types of Radon Gas Tests

This can get confusing quickly…but here is the gist of what you need to know.


Passive Testing Devices

These do not require electricity to function. They can be set by anyone and then mailed to a laboratory. They use methods like charcoal cylinders, alpha track devices, and scintillation measurements. Short term tests are placed out for at least 48 hours and then sent to a lab for analysis. These tests — when done by a top laboratory — are very accurate and they’re an approved testing method by the US EPA and the Colorado Department of Health. Most radon mitigation companies include these tests as post mitigation levels verification.


Popular Brands Include:

  • Airchek
  • Accustar
  • Lowe’s and Home Depot Radon Tests: First Alert, Kidde, Pro Lab Radon Kit

 ***Please note that not all of these kits include analysis. There are some that have a separate fee to get your test results [This is not the case with Airchek tests we provide.]

Active Radon Devices

These are powered Continuous Radon Monitors that are often the size of a shoebox. They’re set out by a technician who typically visits the home twice; once to place the device and a second time 48 hours later to retrieve the machine and read the results. They take hourly measurements and then produce an average radon level for the test period. The cost is usually $100 to $250 and are rarely included in any mitigation cost.

*** One small downside to these devices is that NRPP / AARST Calibration Policy [http://aarst-nrpp.com/wp/calibration/] requires annual calibration and sending the units off to a lab is a real hassle…not every unit out there and in service is properly calibrated and therefore not necessarily accurate.
