Radon Test Results Information | Protech Environmental

We have made arrangements with AirChek, the world’s largest radon testing laboratory, to access their database through this page. Note: If you received an AirChek radon test from us and ordered a written report, the laboratory will also be mailing you a report package directly.

Be sure you have the serial number ready. Then click on the link below to display a table of tests from the database. If your kit number does not appear, it has not yet been analyzed, or was analyzed more than 30 days ago. Contact us to retrieve old data.

The database displays seven items of information for each kit: overall radon reading (pCi/l), test duration, start and end dates, date analyzed, notes, and moisture content of the charcoal in the kit. Before leaving the listing page, you will want to write down or cut and paste all this information.

Compare your radon reading to the EPA Action Level of 4.0 picoCuries per liter. If the reported value is:

4.0 or greater, you should fix the home or perhaps retest. For more guidance, contact us or the Michigan Radon Hotline.
<0.3, The radon level is too low to measure. (Congratulations!)
??????, No reading could be calculated. (See below)

The “Notes” column contains codes that define anything unusual that may make the reported result less precise than usual, or may even prevent calculation of a result:

S: Test too short.

X: Temperature below 30 or above 90 deg F

E: Excessive delay in arriving at lab

L: Test too long, but result representative of last 4 days

W: Excess moisture, usually in combination with an L code

M: Start or end time not provided; 12:00 noon assumed

U: Unsealed kit. Much of the radon may have escaped

P: Kit not fully sealed. Analysis generally not possible

F: Kit damaged or improperly used. Analysis not possible

I: Invalid Test. (Used in combination with another code.)

If “?????” appears in the Start Date and/or End Date column, and there are no other Notes, we will be able to recalculate once you give us the missing information.

Have A Question About Radon Treatment?

Sarah Worsham a year ago

Super quick and efficient service of installing a radon mitigation system in the house we were selling. The installers were very knowledgeable and explained the system and the information to pass on to the buyer's. Definitely would recommend.

By regulation, radon fans must be located outside of the conditioned space of the home.

The regulation stipulates that the exhaust must extend above the roofline. The idea is to keep the exhaust gas from coming back into the house or impinging on patios, walkways, play areas, etc. There are three basic requirements: The exhaust must be

(a) at least ten feet off the ground,
(b) above the eave (not necessarily the edge) of the roof, and
(c) either ten feet away from, or two feet above, windows.

As long as the system is running, the air exiting the pipe keeps rain and bugs out. The system exhaust must be vertical, and upward. The rest of the system is designed so that it pitches back down toward the suction point, so that any water in the system drains back into the soil. Caps and other diverters can cause freeze-up problems from condensation when it’s cold out. Did you know: radon systems can expel hundreds of gallons of water vapor each year?

PVC piping is the most suitable material for the job. Metal downspouts are not intended to be used for gas exhaust applications, and the joints cannot be permanently sealed (they require frequent re-sealing). Downspouts also tend to ice up in the winter, disabling the system just when you need it the most.

Our standard sump covers are transparent, so you can shine a flash light into the sump pit to verify that the sump is working.
