In Illinois radon testing of a home for a real estate transaction must be performed by an IEMA licensed Radon Measurement Professional. Test minimum duration is a 48 hour test, but a 96 hour or longer test is preferred if time is not an issue. Testing not involved in a real estate transaction typically is for a 96 hour period and can be run for a longer duration if time is avaliable.
