§ 8701. Definitions. As used in this article:

1. "Clinical" shall mean activities directly relating to the treatment
or diagnosis of human ailments.

2. "Specialty" or "specialty area" shall mean the following branch or
branches of special competence within medical physics:

(a) "Diagnostic radiological physics" shall mean the branch of medical
physics relating to the diagnostic application of radiation, the
analysis and interpretation of image quality, performance measurements
and the calibration of equipment associated with the production and use
of such radiation, the analysis and interpretation of measurements
associated with patient doses and exposures, and the radiation safety
aspects associated with the production and use of such radiation;

(b) "Medical health physics" shall mean the branch of medical physics
pertaining to the radiation safety aspects of the use of radiation for
both diagnostic and therapeutic purposes, and the use of equipment to
perform appropriate radiation measurements;

(c) "Medical nuclear physics" shall mean the branch of medical physics
pertaining to the therapeutic and diagnostic application of
radionuclides, excluding those used in sealed sources for therapeutic
purposes, the analysis and interpretation of performance measurements
associated with radiation imaging equipment and performance oversight of
radionuclide calibration equipment associated with the use and
production of radionuclides, the analysis and interpretation of
measurements and calculations associated with patient organ doses, and
the radiation safety aspects associated with the production and use of
such radionuclides; and

(d) "Therapeutic radiological physics" or "radiation oncology physics"
shall mean the branch of medical physics relating to the therapeutic
application of radiation, the analysis and interpretation of radiation
equipment performance measurements and the calibration of equipment
associated with the production and use of such radiation, the analysis
and interpretation of measurements associated with patient doses, and
the radiation safety aspects associated with the production and use of
such radiation.

3. "Medical physics" shall mean the branch of physics limited to the
field of radiological physics.

4. "Radiation" shall mean all ionizing radiation above background
levels or any non-ionizing radiation used in diagnostic imaging or in
radiation oncology.

5. "Radiological physics" shall mean diagnostic radiological physics,
therapeutic radiological physics or radiation oncology physics, medical
nuclear physics and medical health physics.

6. "Radiological procedure" shall mean any test, measurement,
calculation or radiation exposure for the purpose of diagnosis or
treatment of any medical condition of a human, including therapeutic
radiation, diagnostic imaging and measurements, and nuclear medicine
procedures.
