Info Sheet

Structure Type is the type of construction used in your home. You can refer to our flowchart to help you choose. Please note that your structure type does not affect our ability to get results from your kit!

Test Floor is the level of your house where you had your kit exposed. For example, your basement would be “basement,” your first floor (ground level) would be “1st floor,” and so on. Please note that your test floor does not affect our ability to get results from your kit.

Only Short Term test kits use Closed House Conditions! First Alert, LabTech, and Kidde products all use Short Term kits.

  • All exterior doors and windows of the entire house are kept closed for at least 12 hours before testing and for the duration of the test. Entry and exit is fine, but doors should not be left open. Interior doors should be used as normal.
  • Heating and cooling systems can be run, provided that they are working in some sort of “re-circulation” mode where they are not having inside and outside air exchange.
  • If you normally run a dehumidifier, then you should run it during testing as normal!
  • Fans venting air to the outside (like stovetop or bathroom fans) should be used as little as possible.
  • Fans circulating air inside the house should be fine to use, but be careful not to expose the radon sampler to a lot of moving air! Make sure that your fan or vent is not blowing at the sampler, and avoid placing it right next to your fan or vent.

If you didn’t test under Closed House Conditions, that doesn’t invalidate your test, but be advised that your results may not be as accurate as they would have been if tested under these conditions. If your house met these requirements during your kit’s exposure, then mark “Yes” for Closed House Conditions!

If you’ve filled out the online form, it’s not necessary to send in a paper copy, though we recommend it just to be extra safe! Both request the same information, so only submitting one is sufficient. You can register your kit online here, or print off a new form here.

This is a space where you can note where your test was placed for testing, such as “living room” or “center of basement.” It can be as general or specific as you prefer – this is typically only for your own reference and does not affect our ability to get results.

The dates and times of your kit’s exposure are used to calculate your radon levels. Radon decays over time, meaning that when we receive your radon sampler, there is less radon present than when you tested! The information you provide on your info sheet (including the dates and times) helps us correct for the difference between when you tested and when our lab receives your kit and is necessary for the calculations portion of our analysis. Incorrect times and dates may lead to inaccurate results, so for best results, please ensure that the dates and times are as accurate as possible!

The test address is needed to correct for time zone differences between your home (or wherever you tested) and our laboratory. Radon decays over time, meaning that when we receive your radon sampler, there is less radon present than when you tested! The information you provide on your info sheet (such as the address) helps us account for the differences in your time zone and our lab’s zone.
