A test is necessary to know whether your need a radon mitigation system. Considering that radon is invisible and cannot be smelled, you need special equipment to know if it is present.
There are two types of radon testing based on the devices used: passive and active.
There is no need for power to work with passive radon testing devices. Charcoal liquid scintillators, charcola canisters, electret ion chamber detectors and alpha-track detectors are examples of such devices. Generally speaking, passive radon devices, both short and long term, are inexpensive.
In contrast to passive testing, active testing uses devices that provide hourly readings as well as average results for the entire test period, thus requiring power to function. These devices, which include continues radon monitors and continuous working level monitors, tend to make this type of testing more costly.
