This Model Legislation provides for certification of persons who apply, or supervise the application of ionizing radiation to human beings for diagnostic or therapeutic purposes. It establishes minimum standards for the education, training, and experience of these persons. It would require examinations for certifications to be administered to licensed practitioners at the professional level and others at the technical level. All persons, both professional and technical, would be required to demonstrate competence in all aspects of the procedures they perform or supervise, but not all need be qualified to undertake all procedures. It would establish separate Medical and Dental Radiologic Technology Boards of Examiners made up of licensed practitioners, radiologic technologists, and other qualified individuals to be appointed by the Governor.
