Sec. 25. (a) A radon laboratory must have both a current, active laboratory license from the department and a current, active laboratory certification in order to manufacture monitors for radon-222, or represent or advertise that it can analyze passive monitors for radon-222, after they have been exposed to the atmosphere. If an entity loses or relinquishes its laboratory certification, its 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 entities seeking certification to manufacture or analyze passive radon monitors as a radon laboratory are as follows:

1. (1) Submission of a sworn affidavit that the entity has read and agrees to adhere to the following standards:

   1. (A) For instrumentation performance specifications: ANSI/AARST "Performance Specifications for Instrumentation Systems Designed to Measure Radon Gas in Air" (ANSI/AARST MS-PC).
   2. (B) For radon measurement quality assurance: ANSI AARST "Radon Measurement Systems Quality Assurance" (ANSI/AARST MS-QA).
2. (2) Proof of current certification by a proficiency program recognized by the EPA.
3. (3) Submission of a quality assurance plan meeting the requirements of ANSI/AARST "Radon Measurement Systems Quality Assurance" (ANSI/AARST MS-QA).
4. (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) 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.

(d) A radon laboratory's results of passive monitors analyzed for radon-222 shall be submitted to the commissioner annually following the procedures outlined in section 28(f) of this rule.
