An Alpha Track testing device is a passive radon detector designed to measure the average radon level in your home over 91 to 365 days. The device contains a special film that records radon exposure over time. Once the test period ends, you mail it to our NELAP-approved laboratory for full analysis.
Place it in a central, frequently used area of the lowest lived-in level. Keep it away from exterior doors, open windows, direct sunlight, or high-moisture areas.
The device must stay in place for at least 91 days and can remain for up to 365 days. The longer the exposure period, the more representative the final reading will be.
Yes, and that’s exactly why long-term tests are valuable. They capture changes across winter, summer, and transitional seasons, giving the most accurate annual average.
You should receive your results within 1 - 2 business days, depending on shipping and lab volume. You can also track the test results and get a full analysis online at Radon.com.
