Radon Qualification Courses

The first step in applying for a Professional or Technician License is to complete an IEMA approved Qualification Course.

Application for License Exam

The second step is to apply for and pass an Illinois approved license/qualification exam.

IEMA is no longer providing radon qualifications examinations. In accordance with the Programmatic Conditions of the State Indoor Radon Grant that requires state grant recipients shall in the absence of an existing state-run process established under a state’s regulatory requirements for credentialing of radon service providers (e.g., state license), the required public list shall only be satisfied by referring consumers to the two currently-recognized, national radon proficiency programs, National Radon Proficiency Program (NRPP) and National Radon Safety Board (NRSB). IEMA in accordance with the Requirements for Issuance or Renewal of Licenses (32 Illinois Administrative Code 422.60) approves the qualification exams of the NRPP and NRSB. Those exams application processes can be found at:



Additional organizations who wish to provide radon qualification exams who are compliant with the credentialing requirements outlined in ISO/IEC 17024:2012, Conformity assessment — General requirements for bodies operating certification of persons, may contact the Agency at 217-782-1325 to submit their credentialing certification and exams for approval.

Application for Professional License 

The final step is to fill out the appropriate application, pay the appropriate fee and include all items listed in Section 422.60 of 32 Illinois Administrative Code 422.  For those applying for a Radon Professional or Laboratory Analysis License include a Quality Assurance Program as part of the license application.  Below are links to the applications for licenses.

Quality Assurance Program Guidance

To assist applicants IEMA provides guidance on writing Quality Assurance Programs.  The instructions in this guidance document describe the areas and information needed by the Agency to evaluate an applicant’s Quality Assurance Program for a professional license.  The regulations require licensees to develop and implement written policies and procedures, which ensure compliance with the Radon Industry Licensing Act and 32 Illinois Administrative Code 422.  The Appendices provide guidance and a sample Quality Assurance Program that an applicant may choose to use in their program.
