CHAPTER 289RADIATION CONTROL
SUBCHAPTER FLICENSE REGULATIONS
RULE §289.256Medical and Veterinary Use of Radioactive Material

    (D) determined dosage or a notation that the total activity is less than 30 µCi (1.1 MBq);

    (E) the date and time of the dosage determination; and

    (F) the name of the individual who determined the dosage.

(y) Authorization for calibration, transmission, and reference sources.

  (1) Any licensee authorized by subsections (n), (o), (p) or (q) of this section for medical use of radioactive material may receive, possess, and use any of the following radioactive material for check, calibration, transmission, and reference use:

    (A) sealed sources, not exceeding 30 millicuries (mCi) (1.11 gigabecquerel (GBq)) each, manufactured and distributed by a person licensed under §289.252(o) of this title or equivalent NRC or agreement state regulations;

    (B) sealed sources, not exceeding 30 millicuries (mCi) (1.11 gigabecquerel (GBq)) each, redistributed by a licensee authorized to redistribute the sealed sources manufactured and distributed by a person licensed under §289.252(o) of this title or equivalent NRC or agreement state regulations, provided the redistributed sealed sources are in the original packaging and shielding and are accompanied by the manufacturer's approved instructions;

    (C) any radioactive material with a half-life not longer than 120 days in individual amounts not to exceed 15 mCi (0.56 GBq);

    (D) any radioactive material with a half-life longer than 120 days in individual amounts not to exceed the smaller of 200 µCi (7.4 MBq) or 1000 times the quantities in §289.202(ggg)(3) of this title; and

    (E) technetium-99m in amounts as needed.

  (2) Radioactive material in sealed sources authorized by this subsection shall not be:

    (A) used for medical use as defined in subsection (c) of this section except in accordance with the requirements in subsection (bbb) of this section; or

    (B) combined (i.e., bundled or aggregated) to create an activity greater than the maximum activity of any single sealed source authorized under this section.

  (3) A licensee using calibration, transmission, and reference sources in accordance with the requirements in paragraph (1) or (2) of this subsection need not list these sources on a specific medical use license.

(z) Requirements for possession of sealed sources and brachytherapy sealed sources. A licensee in possession of any sealed source or brachytherapy source shall:

  (1) follow the radiation safety and handling instructions supplied by the manufacturer and the leakage test requirements in accordance with §289.201(g) of this title and reporting requirements in §289.202(bbb) of this title; and

  (2) conduct a physical inventory at intervals not to exceed six months to account for all sealed sources in its possession. Records of the inventory shall be made and maintained for inspection by the department in accordance with subsection (xxx) of this section and shall include the following:

    (A) model number of each source and serial number if one has been assigned;

    (B) identity of each source and its nominal activity;

    (C) location of each source;

    (D) date of the inventory; and

    (E) identification of the individual who performed the inventory.

(aa) Labeling of vials and syringes. Each syringe and vial that contains a radiopharmaceutical shall be labeled to identify the radioactive drug. Each syringe shield and vial shield shall also be labeled unless the label on the syringe or vial is visible when shielded.

(bb) Surveys for ambient radiation exposure rate.

  (1) In addition to the requirements of §289.202(p) of this title and except as provided in paragraph (2) of this subsection, a licensee shall survey with a radiation detection survey instrument at the end of each day of use all areas where radioactive material requiring a written directive was prepared for use or administered.

  (2) A licensee does not need to perform the surveys required by paragraph (1) of this subsection in an area(s) where patients or human research subjects are confined when they cannot be released in accordance with subsection (cc) of this section or an animal that is confined. Once the patient or human or animal research subject is released from confinement, the licensee shall survey with a radiation survey instrument, the area in which the patient or human or animal research subject was confined.

  (3) A record of each survey shall be retained in accordance with subsection (xxx) of this section for inspection by the department. The record shall include the following:

    (A) date of the survey;

    (B) results of the survey;

    (C) manufacturer's name, model, and serial number of the instrument used to make the survey; and

    (D) name of the individual who performed the survey.

(cc) Release of individuals containing radioactive drugs or implants containing radioactive material.

  (1) The licensee may authorize the release from its control any individual who has been administered radioactive drugs or implants containing radioactive material if the total effective dose equivalent (TEDE) to any other individual from exposure to the released individual is not likely to exceed 0.5 rem (5 mSv). Patients treated with temporary eye plaques may be released from the hospital provided that the procedures ensure that the exposure rate from the patient is less than 5 mrem (0.05 mSv) per hour at a distance of 1 meter from the eye plaque location.

  (2) The licensee shall provide the released individual, or the individual's parent or guardian, with written instructions on actions recommended to maintain doses to other individuals ALARA if the TEDE to any other individual is likely to exceed 0.1 rem (1 mSv). If the TEDE to a nursing infant or child could exceed 0.1 rem (1 mSv), assuming there was no interruption of breast-feeding, the instructions shall also include the following:

    (A) guidance on the interruption or discontinuation of breast-feeding; and

    (B) information on the potential consequences, if any, of failure to follow the guidance.

  (3) The licensee shall maintain for inspection by the department, a record in accordance with subsection (xxx) of this section of each patient released in accordance with paragraph (1) of this subsection. The record shall include the following:

    (A) the basis for authorizing the release of an individual; and

    (B) the instructions provided to a breast-feeding woman. if the radiation dose to the infant or child from continued breast-feeding could result in a TEDE exceeding 0.5 rem (5 mSv).

(dd) Mobile nuclear medicine service. A license for a mobile nuclear medicine service for medical or veterinary use of radioactive material will be issued if the department approves the documentation submitted by the applicant in accordance with the requirements of subsections (f) and (n) of this section. The clients of the mobile nuclear medicine service shall be licensed if the client receives or possesses radioactive material to be used by the mobile nuclear medicine service.

  (1) A licensee providing mobile nuclear medicine service shall:

    (A) obtain a letter signed by the management of each client for which services are rendered that permits the use of radioactive material at the client's address and clearly delineates the authority and responsibility of the licensee and the client;

    (B) check instruments used to measure the activity of unsealed radioactive material for proper function before medical or veterinary use at each client's address or on each day of use, whichever is more frequent. At a minimum, the check for proper function required by this subparagraph shall include a constancy check;

    (C) have at least one fixed facility where records may be maintained and radioactive material may be delivered by manufacturers or distributors each day before the mobile nuclear medicine licensee dispatching its vans to client sites;

    (D) agree to have an authorized physician user directly supervise each technologist at a reasonable frequency;

    (E) check survey instruments for proper operation with a dedicated check source before use at each client's address; and

    (F) before leaving a client's address, survey all areas of use to ensure compliance with the requirements of §289.202 of this title.

  (2) A mobile nuclear medicine service shall not have radioactive material delivered from the manufacturer or the distributor to the client unless the client has a license allowing possession of the radioactive material. Radioactive material delivered to the client shall be received and handled in conformance with the client's license.
