Question & Answer
Review the question and all answer choices
All homes to be tested for radon
The Act does not require all homes to be tested for radon — testing is entirely voluntary and is left to the discretion of the buyer, who may choose to conduct radon testing as part of their due diligence after receiving the disclosure pamphlet.
Sellers to provide a radon disclosure pamphlet
Buyers to pay for radon mitigation
The Act places no financial obligation on buyers to pay for radon mitigation — mitigation costs are a negotiable item between buyer and seller, and the statute is silent on who bears mitigation costs, leaving it entirely to contract negotiation.
Radon levels below 4.0 pCi/L
The 4.0 pCi/L figure is the EPA's action level guideline recommending mitigation when radon levels exceed this threshold, but it is not a legal requirement under the Illinois Radon Awareness Act — the Act does not mandate that any specific radon level be achieved before a property can be sold.
Why is this correct?
The Illinois Radon Awareness Act (420 ILCS 46/25) specifically requires sellers of residential real property to provide buyers with the Illinois Emergency Management Agency's (IEMA) radon disclosure pamphlet titled 'Radon Guide for Real Estate Transactions,' and to disclose any known radon test results or radon mitigation systems in the property. The Act does not require the seller to test the property, does not require the buyer to pay for mitigation, and does not mandate that radon levels meet any specific threshold before a sale can close — it is purely an information and disclosure statute. Sellers who fail to provide the required pamphlet can face civil liability to buyers who suffer damages as a result of the non-disclosure.
Deep Analysis
AI-powered in-depth explanation of this concept
The Illinois Radon Awareness Act (420 ILCS 46/1 et seq.) reflects a public health policy decision to prioritize informed consumer choice over mandatory remediation — the legislature determined that requiring universal testing would be overly burdensome and that the most effective protection was ensuring buyers receive standardized information about radon risks and can make their own informed decisions about testing and mitigation. Radon is a naturally occurring radioactive gas that is the second leading cause of lung cancer in the United States after smoking, making disclosure particularly important in Illinois, which has significant geological radon potential in many counties. The Act's approach of mandating disclosure rather than testing or remediation represents a compromise between property rights, market efficiency, and public health — sellers are not required to test or fix, but buyers must be given the tools to make informed decisions. This disclosure-based model is consistent with Illinois's broader approach to real estate disclosures under the Residential Real Property Disclosure Act.
Knowledge Background
Essential context and foundational knowledge
Illinois enacted the Radon Awareness Act in 1992 following growing scientific consensus in the 1980s about radon's carcinogenic properties and the discovery that Illinois soils, particularly in the northern and central portions of the state, have elevated radon potential due to glacial deposits. The Act was modeled in part on federal EPA guidance and was administered by the Illinois Emergency Management Agency (IEMA), which developed the standardized disclosure pamphlet that sellers are required to provide. The Act has been amended over time to clarify disclosure requirements and to align with updated EPA guidance on radon action levels. Illinois's approach — requiring disclosure but not mandatory testing or remediation — has been adopted by many other states as a balanced public health policy.

Full conversation between instructor and student
Instructor
Hey there, welcome back to our real estate license exam prep podcast. Today, we're diving into a medium difficulty question about the Illinois Radon Awareness Act. How are you doing with the material so far?
Student
I'm doing okay, but this question about the radon act is a bit confusing. Could you clarify what it's asking?
Instructor
Absolutely. The question is asking what the Illinois Radon Awareness Act requires. We have four options: A) All homes to be tested for radon, B) Sellers to provide a radon disclosure pamphlet, C) Buyers to pay for radon mitigation, and D) Radon levels below 4.0 pCi/L. What do you think the correct answer is?
Student
I'm leaning towards B, since radon is a health hazard, and it seems like it would make sense for sellers to provide some kind of disclosure.
Instructor
That's a good start! The correct answer is indeed B. The Illinois Radon Awareness Act requires sellers to provide buyers with a radon disclosure pamphlet and disclose any known test results or mitigation. This is important because it's about disclosure, not about mandating testing or mitigation.
Student
Oh, I see. So it's not about whether the home has been tested or not, but rather about the information being shared?
Instructor
Exactly. This question tests your knowledge of Illinois-specific disclosure requirements, which are crucial for real estate professionals. It's about understanding that the law focuses on providing information, not imposing strict actions or thresholds.
Student
Got it. So why is option A wrong if it's about disclosure?
Instructor
Good question. Option A is incorrect because Illinois law does not require all homes to be tested for radon. Testing is recommended, but it's not mandatory unless required by local ordinance or a contractual agreement.
Student
And option C, why is that wrong?
Instructor
Option C is wrong because the law doesn't assign responsibility for radon mitigation costs to buyers. Payment for mitigation is usually negotiable between parties and depends on the contract terms.
Student
And option D, why isn't that the correct answer?
Instructor
Option D is incorrect because 4.0 pCi/L is the EPA action level guideline, not a requirement under Illinois law. The state law is about disclosure, not about setting a specific legal threshold.
Student
I see. To help remember this, you mentioned a memory technique. Could you share that with me?
Instructor
Sure! The acronym DISC can help. It stands for Disclosure, Information, State-specific, and Compliance. This helps to remember that the Illinois Radon Awareness Act is about providing information as a disclosure requirement, which is state-specific and in line with compliance.
Student
That's a great technique! Thanks for explaining it. I'll definitely use it to study for the exam.
Instructor
You're welcome! Remember, understanding disclosure laws is key in real estate practice. Keep up the good work, and let's move on to the next question. Keep studying, and you'll do great!
Remember 'RADON ACT = PAMPHLET, NOT TEST' using the acronym PAPER: Provide A Pamphlet, Everything else is Recommended (not required). Visualize a seller handing a buyer a pamphlet with a big 'P' on it, while a radon test kit sits on the counter with a question mark — the seller hands the paper, the buyer decides about the test. The pamphlet is the law; the test is a choice.
Remember that Illinois radon law focuses on DISClosure of information rather than requiring specific actions or testing.
For Illinois Radon Awareness Act questions, the answer will always involve 'disclosure' or 'pamphlet' — never mandatory testing, mandatory remediation, or specific radon level thresholds. The Act is a disclosure statute, not a testing or remediation mandate. When you see answer choices about testing requirements or specific pCi/L levels, eliminate them immediately because the Act does not impose those obligations on sellers.
Real World Application
How this concept applies in actual real estate practice
A seller in Naperville, Illinois is selling a ranch-style home with a finished basement. During the listing process, her real estate agent provides her with the IEMA radon disclosure pamphlet to give to prospective buyers. The seller had a radon test conducted three years ago showing levels of 5.2 pCi/L (above the EPA action level), but never installed a mitigation system. Under the Illinois Radon Awareness Act, she must disclose both the pamphlet and the known test result showing elevated radon levels to any buyer. The buyer, upon receiving this information, negotiates a $3,000 seller credit to install a sub-slab depressurization mitigation system — a negotiated outcome that the Act facilitates through disclosure without mandating.
