(a) Upon receipt of information that any person is or may be in violation of any of the provisions of this part or the rules and regulations adopted thereunder, the commissioner or the commissioner's designee may request that the person appear informally and show cause why enforcement action should not be taken. Show cause meetings undertaken pursuant to this section are informal, voluntary and are not contested cases within the definition of the Uniform Administrative Procedures Act, compiled in title 4, chapter 5.

(b) Whenever the commissioner has reason to believe that a violation of any provision of this part or regulation promulgated thereunder or orders issued pursuant thereto has occurred, is occurring, or is about to occur, the commissioner may cause a written complaint to be served upon the alleged violator or violators. The complaint shall specify the provisions or provision of this part or regulations or order alleged to be violated or about to be violated, the facts alleged to constitute a violation thereof, may order that necessary corrective action be taken within a reasonable time to be prescribed in the order and shall inform the violators of the opportunity for a hearing before the commissioner or the commissioner's designee. Any order shall become final and not subject to review unless the person or persons named therein request a hearing in writing, no later than thirty (30) days after the date the order is served.

(c) Whenever the commissioner finds that the public health, safety or welfare is threatened by radiation hazards and that immediate action is necessary to protect the public, an emergency order may be issued stating the issue of the emergency and directing immediate action as required to alleviate the situation. Immediate compliance with the order is required, notwithstanding any request for a hearing.
