Upcoming Webinar: Radon Risk Requirements
The American Lung Association is offering a free one-hour webinar about radon risk reduction requirements for schools, “Considerations for Effective Radon Requirements for Schools.” Only 17 states have any radon requirements for school buildings. Including radon risk reduction strategies in school operation requirements is important in preventing radon-related lung cancer in students and staff. Bringing together experts from states with radon requirements for schools, this panel discussion will offer practical considerations for stakeholders seeking to develop and implement radon requirements for schools. When: September 16th, 1:00pm ET
