concentrations can be reduced by a radon mitigation professional.
Residential real property may present exposure to dangerous levels of
indoor radon gas that may place the occupants at risk of developing radon-induced lung cancer. Radon, a Class A human carcinogen, is the leading cause of
lung cancer in nonsmokers and the second leading cause of lung cancer overall. A
landlord is required to provide the tenant with any known information on radon
test results of the residential real property.

or
(II) Make a reasonable effort to mitigate radon within one hundred eighty
days after being notified that a radon measurement professional has determined
the air concentration of radon is four picocuries per liter or more.
(b) On or after January 1, 2026, this subsection (3) does not apply to a lease
