Article 7 - MEDICAL USES OF RADIOACTIVE MATERIAL
Section R9-7-702 - Definitions.
"Authorized medical physicist" means an individual who meets the requirements in R9-7-711. For purposes of ensuring that personnel are adequately trained, an authorized medical physicist is a "qualified expert" as defined in Article 1.
"Authorized nuclear pharmacist" means a pharmacist who meets the requirements in R9-7-712.
"Authorized user" means a physician, dentist, or podiatrist who meets the requirements in R9-7-719, R9-7-721, R9-7-723, R9-7-727, R9-7-728, or R9-7-744.
"Brachytherapy" means a method of radiation therapy in which a sealed source or group of sealed sources is utilized to deliver beta or gamma radiation at a distance of up to a few centimeters, by surface, intracavitary, intraluminal, or interstitial application.
"CT" means computerized tomography.
"High dose rate after loading brachytherapy" means the treating of human disease using the radiation from a radioactive sealed source containing more than 1 curie of radioactive material. The radioactive material is introduced into a patient's body using a device that allows the therapist to indirectly handle the radiation source during the treatment. For purposes of the requirements in this Article "pulse dose rate after loading brachytherapy" is included in this definition.
"Human research subject" means an individual who is or becomes a participant in research overseen by an IRB, either as a recipient of the test article or as a control. A subject may be either a healthy human, in research overseen by the RDRC, or a patient. "Institutional review board" (IRB) is defined in R9-7-704(B).
"Manual brachytherapy" means a type of brachytherapy in which the brachytherapy sources (e.g., seeds, ribbons) are manually placed topically on or inserted either into the body cavities that are in close proximity to a treatment site or directly into the tissue volume.
"Medical event" means an event that meets the criteria in R9-7-745.
"Medical institution" means an organization in which several medical disciplines are practiced.
"Medical use" means the intentional internal or external administration of radioactive material, or the radiation from it, to an individual under the supervision of an authorized user.
"Nuclear cardiology" means the diagnosis of cardiac disease using radiopharmaceuticals.
"PET" means positron emission tomography.
"Physically present" means that a supervising medical professional is in proximity to the patient during a radiation therapy procedure so that immediate emergency orders can be communicated to ancillary staff, should the occasion arise.
"Prescribed dosage" means the specified activity or range of activity of unsealed radioactive material as documented:
In a written directive; or
In accordance with the directions of the authorized user for procedures performed in accordance with the uses described in Exhibit A.
"Prescribed dose" means:
For gamma stereotactic radiosurgery, the total dose as documented in the written directive;
For teletherapy, the total dose and dose per fraction as documented in the written directive;
For manual brachytherapy, either the total source strength and exposure time or the total dose, as documented in the written directive; or
For remote brachytherapy after loaders, the total dose and dose per fraction as documented in the written directive.
"Radiation Safety Officer" (RSO) for purposes of this Article, and in addition to the definition in Article 1 means an individual who:
Meets the requirements in R9-7-710, or
Is identified as a radiation safety officer on:
A specific medical use license issued by the NRC or Agreement State; or
A medical use permit issued by a NRC master material licensee.
"Radioactive drug" is defined in 21 CFR 310.3(c) and includes a "radioactive biological product" as defined in 21 CFR 600.3, April 1, 2006, both of which are incorporated by reference, published by the Office of Federal Register, National Archives and Records Administration, Washington, DC 20408, and on file with the Department. These incorporated materials contain no future editions or amendments.
"Radioactive Drug Research Committee" (RDRC) means the committee established by the licensee to review all basic research involving the administration of a radioactive drug to human research subjects, taken from 21 CFR 361.1, April 1, 2006, which is incorporated by reference, published by the Office of Federal Register, National Archives and Records Administration, Washington, DC 20408, and on file with the Department. This incorporation by reference contains no future editions or amendments. Research is considered basic re-search if it is done for the purpose of advancing scientific knowledge, which includes basic information regarding the metabolism (including kinetics, distributions, dosimetry, and localization) of a radioactive drug or regarding human physiology, pathophysiology, or biochemistry. Basic research is not intended for immediate therapeutic or diagnostic purposes and is not intended to determine the safety and effectiveness of a radioactive drug in humans.
"Radiopharmaceutical" means any drug that exhibits spontaneous disintegration of unstable nuclei with the emission of nuclear particles or photons and includes any nonradioactive reagent kit or nuclide generator that is intended to be used in the preparation of any such sub-stance. For purposes of this Article radiopharmaceutical is equivalent to radioactive drug.
"Remote after loading brachytherapy device" means a device used in radiation therapy that allows the authorized user to insert, from a remote location, a radiation source into an applicator that has been previously inserted in an individual requiring treatment.
"Sealed Source and Device Registry" means the national registry that contains all the registration certificates, generated by both NRC and the Agreement States, that summarize the radiation safety information for the sealed sources and devices and describe the licensing and use conditions approved for the product.
"Stereotactic radiosurgery" means the use of external radiation in conjunction with a stereotactic guidance device to very precisely deliver a dose.
"Teletherapy" means therapeutic irradiation in which the sealed source of radiation is at a distance from the body.
"Therapeutic dosage" means a dosage of unsealed radioactive material that is intended to deliver a radiation dose to a patient or human research subject for palliative or curative treatment.
"Therapeutic dose" means a radiation dose delivered from a source containing radioactive material to a patient or human research subject for palliative or curative treatment.
"Treatment site" means the anatomical description of the tissue intended to receive a radiation dose, as described in a written directive.
"Unit dosage" means a dosage prepared for medical use for administration as a single dosage to a patient or human research subject without any further manipulation of the dosage after it is initially prepared.
"Written directive" means an authorized user's written order for the administration of radioactive material or radiation from radioactive material to a specific patient or human research subject, as specified in R9-7-707.
