| Testing for radon is normally done using self testing kits (Figure 1 & 2) 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. If you would like to perform the tests yourself, read the Guidelines for Radon Measurements in the Home before placing the detectors.This guide tells you the steps for home radon testing, things to remember when testing and where to place, and not to place, detectors. |

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 radon related particles 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.
