There are different test periods: weeklong, 90-day, and yearlong. Because many factors can influence radon levels in indoor air, a yearlong measurement is the preferred length since it gives more accurate results. But if you can only test for a short amount of time, do the testing during the winter months because all the windows and doors are closed, but do not do it during unusually severe storms or periods of unusually high winds. Alpha track detectors and electret ion detectors are the most common long-term testing devices. The test canister should be put in the lowest level of the home that you use. Put it in the basement if you use your basement. It should not be put in rooms that are high in moisture or that are drafty, such as kitchens, bathrooms, laundry rooms, or hallways. High humidity and drafty conditions can affect the results. Also, do not bother the devices while they are sampling. Experts recommend using two test kits as a way of determining if your test is accurate. If you find one canister has significantly higher levels than the other, you know that the test is inaccurate and inconclusive and has to be redone.
