  • the number of rooms most recently tested
  • the range (lowest reading–highest reading) of the most recent test results in pCi/L
  • a link to all the test reports for each facility

    Note: The U.S. Environmental Protection Agency (EPA) recommended action limit for radon is 4.0 picocuries per liter of air (pCi/L).
