1.18 	commissioners of health and education.

1.20 	buildings for the presence of radon shall and must report the results of its tests to the

2.12 	(c) If a radon test shows that a frequently occupied room has a radon level at or above 
2.13 	four picocuries per liter, a school district or charter school must mitigate or take corrective 
2.14 	action, and retest after corrective measures to show radon reductions. A school district or
