Radon Detection Starts With A Simple Test

Testing is relatively inexpensive, easy and is the only way to know whether you are at risk. These test typically do a good job of detecting radon gas and measuring radon gas concentrations.

Testing for radon is normally done using self-testing kits or electronic radon monitors. Inexpensive passive test kits are available for use in residences. Approved test kits must have passed the EPA’s testing program or be state-certified. Some of these tests measure radon levels over two to three days; others measure it over one to three months. Professional testers may use a method of active sampling that involves the use of a membrane filter and a battery-operated air pump to collect particulate matter to which the radon daughters are attached. After a predetermined time has elapsed, an alpha-particle detector is used to measure the radon level in pico curies per liter (pCi/L). This value is then converted and reported as working levels.
