Systemwide Radon Test Results Information

Radon test result summaries and test reports for Montgomery County Public Schools’ facilities can be accessed below. Within the summary table, information for each school includes:

  • the year when radon testing was performed
  • 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).
