loan

To all:

Was wondering if anyone has ran across any situations where the lender has made it mandatory for the radon ( after a radon test has been done ) to be at a certain level?

I am working with a realtor on a job where she stated that the loan originator ( from the Chicago area ) has noted that they will not guarantee the loan or give a interest rate lock until a radon system is installed in the house in question and provide a test where the radon level is at 2.0 pCi/L or lower.
