In Illinois, radon testing of a home for a real estate transaction must be performed by an IEMA Licensed Radon Measurement Professional. The minimum test period is 48 hours, but 96 hours is preferred if time is not an issue. Testing not involved in a real estate transaction is typically 96 hours and can be run for a longer duration if time is available. Test results are available within 48 hours of test completion.
In Illinois, a homeowner may test their own home if it is their place of residence. This cannot involve a real estate transaction. It is for single family, owner occupied homes without boarders or apartments. Callaway and Associates, Inc. is licensed as an Analytical Lab which will allow us to provide a homeowner with test equipment to perform their own test. This is the same equipment we use for our professional level testing. Test results are available 48 hour after test equipment is returned to Callaway and Associates, Inc.
