Radon law to take effect
When Cecil Keen moved into his Mankato home, he did a radon test in the basement.
“It was off the charts,” said Keen, a professor in the geography department at Minnesota State University.
Keen hired a contractor for $1,500 to mitigate the problem by installing a pipe and fan system to vent the deadly gas from under the basement slab out through the roof.
That experience and ongoing MSU research showing a majority of Mankato homes with high radon levels led Keen and others to successfully push for a state law that requires all new homes to be built with radon mitigation.
The new regulations go into effect June 1.
