Radon testing is done with a Continous Radon Monitor(CRM) that is placed in the property and can take from 2 to 5 days. At the end of the testing period the information is uploaded to a lab in Atlanta where the information is reviewed and certified. The radon monitor collects not only radon levels but also records temperature, humidity, barometric pressure and movement. The results of the test will then be e-mailed to the client.
