New bill introduced in General Assembly...

I saw this little nugget:

Radon test before sale Senate Bill 659 (Clayborne, D-E. St. Louis) amends the Residential Real Property Disclosure Act to require that the seller must have residential property tested for radon before the sale. If it is above a certain level, the seller must mitigate, repair, or alter the premises to reduce the radon level or give the prospective buyer notice of the right to terminate the sale agreement without loss of any earnest money or down payment.

I don't know enough about the prevelance of radon so it's hard for me react. It would clearly increase transactional costs. Right now a Buyer certainly has the right to conduct a radon test at her expense but I don't see it often and it's not mandatory.
