Illinois School Radon Screening Program


  In 2009, the Illinois General Assembly Passed Public Act 96-0417 

  •  Recommends that every occupied school building of a school district be tested every 5 years for radon.
  •  Recommends that new schools of a school district be built using radon resistant construction techniques.
  •  Allows a school district to maintain, make available for review, and notify parents and faculty of test results.
  •  Requires the district to report radon test results to the State Board of Education.
  •  Requires the State Board to prepare a report every 2 years of the results from all schools that have  performed  radon tests, to be submitted to the General Assembly and the Governor.
  •  Authorizes IEMA to allow school staff to test for radon if they have been trained to perform screening tests.
  •  Recommends that if the results of a radon screening test are found to be 4.0 pCi/L or above, the school district may hire a licensed radon professional to perform measurements before any mitigation decisions are made.
  • If radon levels of 4.0 pCi/L or above are found, it is recommended that affected areas be mitigated by a licensed radon mitigation professional with respect to both design and installation.
