Recent History

144.121 X-ray machines and facilities using 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 registered during last 12 months of a biennial registration period. 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.
