Ind. Admin. Code tit. 410, r. 5.1-1-24 – Certification of primary radon testers

Sec. 24. (a) A primary radon tester must have both a current, active tester license from the department and a current, active measurement certification from an EPA recognized proficiency program in order to test for radon-222, or represent or advertise that the individual can test for radon-222, in a building. If an individual loses or relinquishes their measurement certification through the EPA recognized proficiency program, their Indiana license will be immediately suspended, and will remain suspended until the national certification is renewed or the term of the Indiana license expires, whichever comes first.

(b) The requirements for all individuals seeking certification to test as a primary radon tester are as follows:

(1) Submission of a sworn affidavit that the individual has read and agrees to adhere to the following standards:
1. (A) For testing in residential buildings: ANSI/AARST "Protocol for Conducting Radon and Radon Decay Product Measurements in Homes" (ANSI/AARST MAH).
2. (B) For testing in multifamily buildings: ANSI/AARST "Protocol for Conducting Radon and Radon Decay Product Measurements in Multifamily Buildings" (ANSI/AARST MAMF).
3. (C) For testing in schools and large buildings: ANSI/AARST "Protocol for Conducting Radon and Radon Decay Product Measurements in Schools and Large Buildings" (ANSI/AARST MALB).
(2) Proof of successful completion of a measurement training course and exam and current certification by a proficiency program recognized by the EPA.
(3) Submission of a quality assurance plan meeting the requirements of ANSI/AARST "Radon Measurement Systems Quality Assurance" (ANSI/AARST MS-QA).
(4) Submission of a complete and accurate application form prescribed by the commissioner along with a fee of one hundred dollars ($100). An application will not be considered complete unless the required fee has been submitted.

(c) If using an instant readout device for radon-222 detection, evidence that the calibration and accuracy tests required by ANSI/AARST "Radon Measurement Systems Quality Assurance" (ANSI/AARST MS-QA) are being met shall be provided to the commissioner yearly. Primary radon tester licensees are not required to be licensed as a laboratory if they are only analyzing the results from their personal instant readout device or electret ion chamber detection devices.
