Preparing questions about arranging a radon test
Learn essential steps for organizing radon testing in Illinois real estate, focusing on professional licensing and mandatory buyer disclosures for your home.
The short answer
Illinois sellers must provide the IEMA-OHS radon pamphlet and disclosure form before signing contracts. Because sellers lack a duty to investigate, buyers should prioritize independent testing. Arrange for licensed professionals, as IEMA-OHS mandates certification for radon testing services. Use this phase to confirm the professional's credentials and clarify testing protocols to ensure data accuracy during your transaction.
Verifying Professional Credentials
Illinois law requires radon testing to be conducted by licensed professionals. You must verify that your tester holds a valid IEMA-OHS license. Do not assume that general home inspectors are authorized to perform radon measurements. Always request the specific license number and confirm it remains active through official state resources.
Decision Question: Have you documented the testing company's IEMA-OHS license number, expiration date, and confirmed their credentials before finalizing your service agreement?
Evaluating Mandatory Disclosures
The Illinois Radon Awareness Act requires sellers to provide a specific pamphlet and disclosure form. This documentation is a legal prerequisite for the transaction. If the seller fails to deliver these materials, you are not receiving the legally mandated information regarding known hazards or necessary state-regulated disclosures.
Decision Question: Have you confirmed receipt of both the IEMA-OHS pamphlet and the Illinois Disclosure of Information on Radon Hazards form?
Clarifying Testing Protocols
Not all testing methods are identical. Ask your professional about the specific protocols they follow to ensure compliance with Illinois guidelines. Understand the duration of the test and how environmental conditions might impact results. This clarity helps prevent disputes regarding test validity after the report is generated.
Decision Question: What specific IEMA-OHS protocols will the tester follow for this property and how will they ensure the testing device remains undisturbed?
Planning for Contingency Dates
Radon testing is distinct from other property inspections. You must manage the time required for testing against your contract deadlines. If results show high levels, you will need time to interpret these with your legal representative. Do not wait until the final hour of your inspection window to coordinate testing.
Decision Question: Is the test scheduled to conclude at least three business days before your inspection deadline to allow for proper data review?

Common questions
Must a seller pay for my radon test?
No. The Illinois Radon Awareness Act requires the seller to disclose information and provide specific pamphlets, but it does not mandate that they cover the costs of a buyer-initiated test.
Can I use a DIY test kit for the real estate transaction?
Consult your attorney. Illinois law emphasizes the use of licensed professionals for testing in real estate transactions to ensure the data holds credibility during contract negotiations.
