144.121 X-RAY MACHINES; OTHER SOURCES OF IONIZING RADIATION.
    Subdivision 1. Registration; fees. The fee for the registration for x-ray machines and
other sources of ionizing radiation required to be registered under rules adopted by the state
commissioner of health pursuant to section 144.12, shall be in an amount as described in
subdivision 1a pursuant to section 144.122. The registration shall expire and be renewed as
prescribed by the commissioner pursuant to section 144.122.
    Subd. 1a. Fees for x-ray machines and other sources of ionizing radiation. A facility with
x-ray machines or other sources of ionizing radiation must biennially pay an initial or biennial
renewal registration fee consisting of a base facility fee of $132 and an additional fee for each
x-ray machine or other source of ionizing radiation as follows:

	(1)	medical or veterinary equipment		$ 106
	(2)	dental x-ray equipment		$ 66
	(3)	accelerator		$ 132
	(4)	radiation therapy equipment		$ 132
	(5)	x-ray equipment not used on humans or animals		$ 106
	(6)	devices with sources of ionizing radiation not used on humans or animals		$ 106
	(7)	sources of radium		$ 198

    Subd. 1b. Penalty fee for late registration. Applications for initial or renewal registrations
submitted to the commissioner after the time specified by the commissioner shall be accompanied
by a penalty fee of $20 in addition to the fees prescribed in subdivision 1a.
    Subd. 1c. Fee for x-ray machines and other sources of ionizing radiation. The initial
registration fee of x-ray machines or other sources of radiation required to be registered during the
last 12 months of a biennial registration period will be 50 percent of the applicable registration fee
prescribed in subdivision 1a.
    Subd. 2. Inspections. Periodic radiation safety inspections of the sources of ionizing
radiation shall be made by the state commissioner of health. The frequency of safety inspections
shall be prescribed by the commissioner on the basis of the frequency of use of the source of
ionizing radiation; provided that each source shall be inspected at least once every four years.
    Subd. 3. Exemption. Notwithstanding rules adopted by the commissioner under section
144.12, subdivision 1, clause (15), practitioners of veterinary medicine are not required to conduct
densitometry and sensitometry tests as part of any ionizing radiation quality assurance program.
    Subd. 4. Radiation monitoring. Whenever involved in radiation procedures, practitioners
of veterinary medicine and staff shall wear film-based radiation monitoring badges to monitor
individual exposure. The badges must be submitted periodically to a dosimetry service for
individual exposure determination.
    Subd. 5. Examination for individual operating x-ray equipment. After January 1, 1997,
an individual in a facility with x-ray equipment for use on humans that is registered under
subdivision 1 may not operate, nor may the facility allow the individual to operate, x-ray
equipment unless the individual has passed an examination approved by the commissioner of
health, or an examination determined to the satisfaction of the commissioner of health to be an
equivalent national, state, or regional examination, that demonstrates the individual's knowledge
of basic radiation safety, proper use of x-ray equipment, darkroom and film processing, and
quality assurance procedures. The commissioner shall establish by rule criteria for the approval of
examinations required for an individual operating an x-ray machine in Minnesota.
    Subd. 6. Inspection. At the time a facility with x-ray equipment is inspected by the
commissioner of health in accordance with subdivision 2, an individual operating x-ray equipment
in the facility must be able to show compliance with the requirements of subdivision 5.
    Subd. 7.[Repealed, 1999 c 86 art 2 s 6]
    Subd. 8. Exemption from examination requirements; operators of certain bone
densitometers. (a) This subdivision applies to a bone densitometer that is used on humans to
estimate bone mineral content and bone mineral density in a region of a finger on a person's
nondominant hand, gives an x-ray dose equivalent of less than 0.001 microsieverts per scan, and
has an x-ray leakage exposure rate of less than two milliroentgens per hour at a distance of
one meter, provided that the bone densitometer is operating in accordance with manufacturer
specifications.
(b) An individual who operates a bone densitometer that satisfies the definition in paragraph
(a) and the facility in which an individual operates such a bone densitometer are exempt from the
requirements of subdivisions 5 and 6.
