Detekt Radon Short Term Test Kit

Detekt says the kit uses a charcoal adsorption method to capture radon from the air. The detector sits open in the room for the test period; at the end you seal it and send it to a certified laboratory in the included mailer. Detekt's own article on radon testing explains the principle: radon gas diffuses into a container where it is adsorbed onto activated charcoal, and after the exposure period the device is sealed and analyzed. Detekt adds that the kit screens your home's air with no electronics or technical setup, so nothing in it runs on power or shows a number.

The National Radon Safety Board describes the same method, which it codes AC for activated charcoal adsorption: an airtight container with activated charcoal is opened in the area to be sampled and radon in the air adsorbs onto the charcoal granules; at the end of the sampling period the container is sealed and may be sent to a laboratory, where the gamma decay from the adsorbed radon is counted. The board adds that charcoal detectors, depending on design, are deployed from 2 to 7 days, and that because charcoal keeps adsorbing and releasing radon, the method does not give a true integrated measurement over the exposure time.

The EPA names charcoal canisters among the passive detectors most commonly used for short-term testing, and describes passive devices as needing no power: they are exposed to the air in the home for a specified period of time and then sent to a laboratory for analysis. Detekt says its kit reports radon in picocuries per liter (pCi/L) to show whether a home exceeds the EPA action level of 4 pCi/L.

The exposure window is two to seven days. Detekt's product page says the kit measures radon over a two to seven day period, and its answers to common questions say the test requires 2-7 days of exposure time in your home, followed by lab analysis. Detekt's text does not say what happens to a sample left out for less than two days or more than seven, so follow the instructions in the box. The EPA says all radon tests should be taken for a minimum of 48 hours.

Detekt gives its result timing four ways, each counted from a different point. Its answers say a digital report arrives by email within 72 hours after the lab receives the test kit; that after you mail the sealed detector you will typically receive certified results within 3-5 business days; and that the whole process takes approximately 1-2 weeks. The product description says results are available in 2-7 days after testing. Add the exposure and the mail to any of these.

The EPA counts any test from two to 90 days as short-term. Because radon levels tend to vary from day to day and season to season, it says a long-term test, more than 90 days, is more likely to tell you a home's year-round average. After a first short-term result at or above 4 pCi/L, the EPA says to follow up with either a long-term test or a second short-term test, and it suggests considering a fix between 2 and 4 pCi/L.
