precautionary principle to minimize radiation doses and releases of radioactive
materials with using practical, cost-effective measures [4,36,37]. Therefore, we
recommend that a federally mandated maximum radon limit be established for
schools and other buildings with public access, as should guidelines regarding the
timeframe for initial testing and the frequency of re-testing for radon. States may
then work with the USEPA to develop a state-specific radon testing plans based on
the risk related to the specific geographic locations of the schools. The USEPA may
also offer standardized online radon testing training courses and materials for
school employees to reduce state costs and improve the consistency, accuracy, and
reproducibility of the test results.
Acknowledgments
The authors would like to extend our sincere appreciation to the staff working for
the radon programs in the states of Florida, Iowa, Illinois, Kansas, Ohio, Texas,
Virginia, and West Virginia for their guidance, advice and clarification on radon
testing in school policies in their states.
