Types of Radon Testing

Radon air levels are measured in homes and commercial buildings two different ways. Passive testing involves using canisters or trays, which will absorb the radon gas. The amount of radon is calculated as a function of the radon absorption per exposure time. Active testing involves using a continuous run monitor for a minimum of 48 hours. The continuous run monitor takes real-time measurements using sensitive sensor technology. 

Passive Radon Monitoring

The pros of using passive radon monitor is that it does not require access to power, the sampling technique is easy, and the analysis is inexpensive. The cons are that the results may not be as accurate as continuous radon monitoring.
