Minn. Stat. § 144.121, subd. 5, states,

(a) After January 1, 2008, an individual in a facility with x-ray equipment for use on humans that is registered under Minn. Stat. § 144.121 subd. 1, may not operate, nor may the facility allow the individual to operate, x-ray equipment unless the individual has passed a national examination for limited x-ray machine operators that meets the requirements of paragraphs (b) and (c) and is approved by the commissioner of health.

(b) The commissioner shall establish criteria for the approval of examinations based on national standards, such as the examination in radiography from the American Registry of Radiologic Technologists, the examination for limited scope of practice in radiography from the American Registry of Radiologic Technologists for limited x-ray machine operators, and the American Registry of Chiropractic Radiography Technologists for limited radiography in spines and extremities; or equivalent examinations approved by other states. Equivalent examinations may be approved by the commissioner, if the examination is consistent with the standards for educational and psychological testing as recommended by the American Education Research Association, the American Psychological Association, the National Council on Measurement in Education, or the National Commission for Certifying Agencies. The organization proposing the use of an equivalent examination shall submit a fee to the commissioner of $1,000 per examination to cover the cost of determining the extent to which the examination meets the examining standards. The collected fee shall be deposited in the state treasury and credited to the state government special revenue fund.

(c) The examination for limited x-ray machine operators must include:

(1) radiation protection, equipment maintenance and operation, image production and evaluation, and patient care and management; and

(2) at least one of the following regions of the human anatomy: chest, extremities, skull and sinus, spine, or ankle and foot. The examinations must include the anatomy of, and positioning for, the specific regions.

(d) A limited x-ray operator who is required to take an examination under this subdivision must submit to the commissioner an application for the examination, a $25 processing fee, and the required examination fee set by the national organization offering the examination. The processing fee and the examination fee shall be deposited in the state treasury and credited to the state government special revenue fund. The commissioner shall submit the fee to the national organization providing the examination.

Minn. Stat. § 144.121, subd. 5a, states,

(a) A limited x-ray operator may only practice medical radiography on limited regions of the human anatomy for which the operator has successfully passed an examination identified in subdivision 5, unless the operator meets one of the exemptions described in paragraph (b). The operator may practice using only routine radiographic procedures, for the interpretation by and under the direction of a licensed practitioner, excluding computed tomography, the use of contrast media, and the use of fluoroscopic or mammographic equipment.

(b) This subdivision does not apply to:
(1) limited x-ray machine operators who passed the examination that was required before January 1, 2008;
(2) certified radiologic technologists, licensed dental hygienists, registered dental assistants, certified registered nurse anesthetists, and registered physician assistants;
(3) individuals who are licensed in Minnesota to practice medicine, osteopathy, chiropractic, podiatry, or dentistry; and
