RECORDKEEPING REQUIREMENTS
Section 120.433 - General Administrative Requirements for Facilities Using Therapeutic Radiation Machines

Current through Register 1531, September 27, 2024

(A) Administrative Controls. The registrant shall be responsible for directing the operation of the therapeutic radiation machines which have been registered with the Agency. The registrant or the registrant's agent shall ensure that the requirements of 105 CMR 120.430 are met in the operation of the therapeutic radiation machine(s).

(B) Prohibition A therapeutic radiation machine which does not meet the provisions of 105 CMR 120.000 shall not be used for irradiation of patients.

(C) Training for Therapeutic Radiation Machine Authorized Users The registrant for any therapeutic radiation machine subject to 105 CMR 120.436 or 120.437 shall require the authorized user to be a physician who:

(1) Is certified in:
(a) Radiology or therapeutic radiology by the American Board of Radiology; or

(b) Radiation oncology by the American Osteopathic Board of Radiology; or

(c) Radiology, with specialization in radiotherapy, as a British "Fellow of the Faculty of Radiology" or "Fellow of the Royal College of Radiology"; or

(d) Therapeutic radiology by the Canadian Royal College of Physicians and Surgeons.

(2) Is in the active practice of therapeutic radiology, and has completed 200 hours of instruction in basic radiation techniques applicable to the use of an external beam radiation therapy unit, 500 hours of supervised work experience, and a minimum of three years of supervised clinical experience.
(a) To satisfy the requirement for instruction in 105 CMR 120.433(C)(2), the classroom and laboratory training shall include:
1. Radiation physics and instrumentation;

2. Radiation protection;

3. Mathematics pertaining to the use and measurement of ionization radiation; and

4. Radiation biology.

(b) To satisfy the requirement for supervised work experience, training shall be under the supervision of an authorized user and shall include:
1. Review of the full calibration measurements and periodic quality assurance checks;

2. Evaluation of prepared treatment plans and calculation of treatment times/patient treatment settings;

3. Using administrative controls to prevent misadministrations;

4. Implementing emergency procedures to be followed in the event of the abnormal operation of a external beam radiation therapy unit or console; and,

5. Checking and using radiation survey meters.

(c) To satisfy the requirement for a period of supervised clinical experience, training shall include one year in a formal training program approved by the Residency Review Committee for Radiology of the Accreditation Council for Graduate Medical Education or the Committee on Postdoctoral Training of the American Osteopathic Association and an additional year years of clinical experience in therapeutic radiology under the supervision of an authorized user. The supervised clinical experience shall include:
1. Examining individuals and reviewing their case histories to determine their suitability for external beam radiation therapy treatment, and any limitations/ contraindications;

2. Selecting proper dose and how it is to be administered;

3. Calculating the therapeutic radiation machine doses and collaborating with the authorized user in the review of patients' progress and consideration of the need to modify originally prescribed doses and/or treatment plans as warranted by patients' reaction to radiation; and,

4. Post administration follow up and review of case histories.

(d) Notwithstanding the requirements of 105 CMR 120.433(C)(1) and (2), the registrant for any therapeutic radiation machine subject to 105 CMR 120.436 may also submit the training of the prospective authorized user physician for Agency review on a case by case basis.

(e) A physician shall not act as an authorized user for any therapeutic radiation machine until such time as said physician's training has been reviewed and approved by the Agency.

(D) Training for Qualified Medical Physicist for Radiation Therapy. The registrant for any therapeutic radiation machine subject to 105 CMR 120.436 or 120.437 shall require the Qualified Medical Physicist to:

(1) Be registered with the Agency, under the provisions of 105 CMR 120.026, as a provider of radiation services in the area of calibration and compliance surveys of external beam radiation therapy units; and,

(2) Be certified by the American Board of Radiology in:
(a) Therapeutic radiological physics; or

(b) Roentgen-ray and gamma-ray physics; or

(c) X-ray and radium physics; or

(d) Radiological physics; or,

(3) Be certified by the American Board of Medical Physics in Radiation Oncology Physics; or,

(4) Be certified by the Canadian College of Medical Physics.

(E) Qualifications of Operators.

(1) Individuals who will be operating a therapeutic radiation machine for medical use shall possess a valid Massachusetts License as a Radiologic Technologists in Radiation Therapy.

(2) The names and the respective training records of all personnel currently operating a therapeutic radiation machine shall be kept on file at the facility. Information on former operators shall be retained for a period of at least two years beyond the last date they were authorized to operate a therapeutic radiation machine at that facility.

(F) Written safety procedures and rules shall be developed by a Qualified Medical Physicist and shall be available in the control area of a therapeutic radiation machine, including any restrictions required for the safe operation of the particular therapeutic radiation machine. The operator shall be able to demonstrate familiarity with these rules.

(G) Individuals shall not be exposed to the useful beam except for medical therapy purposes and unless such exposure has been ordered in writing by an authorized user meeting the requirements of 105 CMR 120.433(C) who is specifically identified on the Certificate of Registration. 105 CMR 120.433(G) specifically prohibits deliberate exposure of an individual for training, demonstration or other non-healing-arts purposes.

(H) Visiting Authorized User. Notwithstanding the provisions of 105 CMR 120.433(G), a registrant may permit any physician to act as a visiting authorized user under the term of the registrant's Certificate of Registration for up to 60 days per calendar year under the following conditions:

(1) The visiting authorized user has the prior written permission of the registrant's management and, if the use occurs on behalf of an institution, the institution's Radiation Safety Committee; and

(2) The visiting authorized user meets the requirements established for authorized user(s) in 105 CMR 120.433(C)(1) and (2); and
