example, the school radon testing guide recommends that the school administration
conducts an informational meeting to provide an overview of scheduled radon
testing and address any questions/concerns to individuals responsible for radon
testing and representatives of parent and teacher organizations. In addition, in
Connecticut, it is recommended that two weeks prior to a scheduled radon testing, a
formal letter of radon testing notification is required to be sent to parents of students
and school employees, along with radon educational materials. Proper notification,
in a transparent and timely way, will encourage civil society stakeholders to voice
their concerns and participate in monitoring policy and program implementation.
3.3. State Radon Mitigation Requirements
In the United States, a radon level below 2 pCi/L is accepted as normal (Radon
Zone 3). Indoor Radon level between 2 and 4 pCi/L is designated as Radon Zone 2
and the USEPA suggests mitigation to be performed. Indoor radon level of above 4
pCi/L (Action Level) is categorized as Radon Zone 1 where mitigation is deemed
necessary because an increased risk for lung cancer has been observed at that
exposure level in smokers and non-smokers [25]. However, radon mitigation
requirements in most states varies substantially and often are not enforced (Table
1). For example, the statute of state of Colorado doesn’t require schools to mitigate,
so it’s up to the school district and its constituents to address mitigation issues [24].
