Minnesota home owners and real estate agents have learned how to navigate the state's new radon disclosure law.
Health experts pushed for the rule that requires home sellers to disclose any information they have about the presence of radon in their houses.
Minnesota Public Radio reports the odorless, colorless gas is the leading cause of lung cancer in non-smokers. An estimated 700 Minnesotans die from long-term radon exposure per year.
The local real estate industry was initially worried radon disclosure would make it harder to sell homes. But agents say they navigated the new law by resolving radon problems.
It usually costs around $1,500 to rid a home of radon.
